Disrupting The Heteronormative Mindset In Teacher Preparation Through Inclusive Children's Literature, Denise I. Donahue

USF Tampa Graduate Theses and Dissertations

Because of discrimination that presents itself through bullying based on identity, and the lack of positive LGBTQIA+ representation within classroom lessons, there is a need for a higher quality of preparation for teachers in order to create inclusive environments.

All teachers, particularly new teachers, need to know how to effectively work with diverse learners to meet their needs academically, emotionally and socially. This includes preparing teachers to instruct students and work with families who include LGBTQIA+ members. LGBTQIA+ students are often marginalized, discounted, harassed or invisible. (Kosciw, Greytak, Zongrone, Clark, & Truong, 2018). There is a need for a higher …

But, I Don’T Believe It’S About Race’: Challenging Fallacies Of Race And Racism Amongst Early Childhood Educators In Ontario, Beverly-Jean J. Daniel, Kerry-Ann Escayg

Journal of Curriculum, Teaching, Learning and Leadership in Education

There is the continued belief that children do not see race and that they are racially innocent. This belief is evidenced in early childhood environments and influences the practices of the instructors in these settings. However, research continues to show that children do see and react to varying markers of race. This research project focused on early childhood educators’ interpretations of children’s racially coded behaviours and interactions. The results revealed four central themes: racial evasiveness; racial dis-ease; parental role in promoting racism; and limited educational preparation. This study contributes to the growing body of research on children, race, and early …

Politicizing Early Childhood Education And Care In Ontario: Race, Identity And Belonging, Zuhra E. Abawi, Rachel Berman Dr.

Journal of Curriculum, Teaching, Learning and Leadership in Education

The Early Childhood Education and Care (ECEC) landscape, much like the K-12 education system in Ontario, is largely encompassed by bias-free, neutral and colourblind narratives of identity and social location (Author 1, 2018). These discursive practices portray young children and early learning settings as raceless and equal spaces that engage children in interactions and discussions of race and identity are inappropriate. Education in Ontario and Canada as an entity is marked by myth of the Canadian nation-state (Thobani, 2007) through celebratory, themed, recognition-based initiatives that mark differences, while leaving the status quo of whiteness unchallenged and intact (DiAngelo, 2018). The …

Characterization Of The Semi-Permeable Layer In Seed Of Elymus Nutans, Jing Zhou, Yanrong Wang, Xueqing He

IGC Proceedings (1977-2023)

A semi-permeable layer of the seed coat exists in many species which allows controlled water uptake and gas ex-change, while preventing solute transport (Beresniewicz et al. 1995). This layer could act as a barrier to apoplastic permeability and radicle emergence (Salanenka et al. 2009). It could also restrict the tetrazolium viability test and the electrical conductivity vigour test applied to evaluate seed quality (Yan and Wang 2008; Zhou and Wang 2012). An earlier study reported that semi-permeable layers exist in grass species, but recently research has shown that the layer was not found in seeds of oat (He …

White Clover Seed Production Response To Irrigation, Ana L. Pereira, Ariel Pimienta, Pamela Aguirre, Marita Ferriso, Virginia Pravia

IGC Proceedings (1977-2023)

White clover is more sensitive to soil water restriction compared to other perennial legumes, due to its shallow root system and poor stomatal control. Its undetermined growth is influenced by soil water content and seed production is reduced when vegetative growth is not restricted through irrigation management. Restricting the amount of soil available water during the bloom stage reduced plant vegetative growth and increases seed production (Clifford, 1986). In Uruguay, there is not a defined rainy season, and annual average ranges between 1100 and 1300mm. However, due to higher water demand during late spring and summer, a water deficit period …

Does Scarification Time Affect Hydrotime Model Parameters Of Vicia Angustifolia Seed Germination?, Xiaowen Hu, Tingshan Li, Yanrong Wang

IGC Proceedings (1977-2023)

Hard seed, also classified as physical dormancy, is very common in forage legumes (Baskin and Baskin 2004). Many methods, based on scarifying seed coat have been developed such as mechanical scarification, chemical scarification to soft hard seed (Baskin and Baskin 1998). Hydrotime is a way to describe the relationship between water potential (Ψ) and seed germination rates and percentages (Bradford 1990) The hydrotime model has proven to be useful for understanding the physiological mechanism of seed germination and has been suggested as a tool to describe seed germination time in relation to water condition (Alvarado and Bradford 2002). …

Production Of Alfalfa Seed In Italy, Alessandra Sommovigo, Domenica Iraci Capuccinello, Marta Giannini

IGC Proceedings (1977-2023)

Alfalfa (Medicago sativa) is considered the largest cultivated forage species in the temperate areas in the world and in Italy covers about 700,000 ha. This species is important for the ability to produce a good quality forage with low input. Alfalfa seed production is spread throughout Italy, France and Spain (Fig. 1). In Italy, about 47% of forage area is planted with alfalfa and the Italian regions where alfalfa seed is mainly produced are Emilia Romagna, Marche and Tuscany (Fig. 2). In 2012 the area for the production of alfalfa seed was 20,906 ha with a seed production …

The Italian Catalogue Of Herbage Varieties, M. Giolo, Giovanni Corsi, N. Mugueta, F. Sorgoni, Pier Giacomo Bianchi, Renzo Torricelli, Mario Falcinelli

IGC Proceedings (1977-2023)

With 3.4 million hectares, permanent grassland covers 25.8% of Italian U.A.A. (Usable Agricultural Area). Most of this is located in hilly and mountainous areas and is important for the stability of the soil even if their productivity is low. Alfalfa and annual forages cover 1.8 million hectares (C.R.P.A. 2010). Italy’s large longitudinal extension (between latitudes 35° and 47° N), delivers a great variety of climates (Fig. 1). The northern regions bordering the rest of Europe differ greatly from the southern regions surrounded by the Mediterranean Sea.

Criteria For The Registration Of Medicago Polymorpha L. And Lolium Rigidum Gaud. Varieties In A Voluntary Register In Italy, Luciano Pecetti, Giovanni Corsi, Federico Sòrgoni, Pier Giacomo Bianchi, Mario Falcinelli, Renzo Torricelli

IGC Proceedings (1977-2023)

Extensive and semi-extensive livestock systems in Southern Europe rely largely on permanent pastures, the productivity of which could be improved by sowing adapted species. Native forage species are a valuable tool for Mediterranean livestock production, owing to their specific adaptation to the harsh environment (featuring prolonged and severe spring-summer drought) and their generally good tolerance to grazing. Annual, self-reseeding species are able to cope with the prevailing drought stress by terminating the vegetative phase and setting seed before the onset of the stressful period, and enhance the durability of the sward by their self-reseeding capacity and subsequent seedling regeneration. Subterranean …

Trinexapac-Ethyl Application Increased Seed Yield Of Diploid Red Clover (Trifolium Pratense L.), Dave Monks

IGC Proceedings (1977-2023)

Red clover (Trifolium pratense L.) is a perennial legume grown for forage that, when grown with a seed yield focus in New Zealand, averages 260 kg seed/ha (Clifford, 1979). One way to shift the production focus from biomass to seed yield is the use of plant growth regulators (PGRs). Prior work with PGRs in legume seed production has centred on the gibberellin biosynthesis inhibitors paclobutrazol, uniconazol and cycocel that aim to increase the harvest index of a crop by reducing the ratio of vegetative to reproductive biomass. Inhibiting gibberellin synthesis decreases cell division and cell enlargement; reducing the length …

Nitrogen Uptake And Utilisation In Red Fescue (Festuca Rubra Var. Rubra) For Seed Production, René Gislum, Birte Boelt

IGC Proceedings (1977-2023)

Application and utilisation of nitrogen (N) is important from both an agronomic and environmental point of view. Increased utilisation of applied N will increase seed yield and the amount of N removed in the harvested straw and seed and concomitantly lower the amount of N than can potentially leach to ground and surface water. From an agronomic viewpoint it is important to understand the relationship between higher N uptake and seed yield. We know from several field experiments that the current year has a large impact on the uptake and utilisation of applied N due to soil available water, temperature …

Effect Of Gamma Irradiation On Seed Germination Traits Of Bromus Inermis, Ghasem Ali Dianati Tilaki, Arezu Alizadeh, Behnam Naserian Khiabani

IGC Proceedings (1977-2023)

Ionizing radiation technology and in particular gamma radiation is developing as a useful treatment in crop production. Gamma rays cause different physiological and morphological responses in cells and tissues that appear as an increase in germination speed, germination capacity and growth of the leaves (Amjad and Anjum 2007). Several reports on the stimulatory affects on plant growth when exposed to irradiation techniques with radioactive rays at low doses are available (Charbaji and Nabulsi 1999; Moussa 2006). Seed treatment with low doses of gamma rays resulted in a significant increase in germination traits, plant vigor and yield attributes of wheat (Melki …

Germination Of Tropical Forage Seeds Stored In Ambient And Controlled Temperature And Humidity Conditions, Michael D. Hare, Supaphan Phengphet, Theerachai Songsiri, Naddakorn Sutin, Eduardo Stern

IGC Proceedings (1977-2023)

Storage of tropical forage seeds in the humid tropics is crit-ical in order to safeguard germination. Storing Mulato hybrid brachiaria (Brachiaria ruziziensis x B. brizantha) seed under ambient conditions could be safely done for 8-12 months in Thailand, but rapid deterioration in viability occurred with longer storage, with seed being totally non-viable after 20 months storage (Hare et al. 2008). However, Mulato seeds kept in cold storage (10°C and 40% RH) for 3 years still maintained 80% germination. Similar results were found in northern Australia (Hopkinson and English 2005) where loss of viability of Panicum maximum, …

Advances In Nutrient Management Of Grass Seed Crops, René Gislum, Birte Boelt

IGC Proceedings (1977-2023)

Nutrient management of herbage grass seed crops is just as complex as for other agricultural crops when the aim is to optimise economic net return and minimise environmental impact. The use of economic optimum nitrogen (N) application rate (ECO-N) defined as the N application rate that maximise net return for the seed grower is an easy and applicable method for seed growers. Besides the economic advantages of implementing ECO-N there is an additional positive environmental effect as ECO-N is lower than the N rate that maximises seed yield and a lower N application rate will concomitantly lower the potential risk …

Effects Of Storage Conditions On Endophyte And Seed Viability In Pasture Grasses, David E. Hume, Stuart D. Card, M. Philip Rolston

IGC Proceedings (1977-2023)

Several important temperate pasture grasses have co-evolved with mutualistic Epichloë fungal endophytes. These endophytes impart beneficial attributes to their host as they enhance the fitness of the grass when under biotic and abiotic stresses. The asexual species of these fungi (formerly classed as Neotyphodium) are obligate symbionts, and efficiently colonise newly formed tillers and infect seed by direct colonisation of the embryo. These endophytes are strictly seed transmitted. Survival of the fungus in this seed is therefore critical for the dissemination of endophyte-infected seed to grassland farmers. Longevity of endophyte in stored seed is primarily determined by the length …

Managing Seed Dormancy In Forage Legumes And Grasses: An Update, Yanrong Wang, Xiaowen Hu

IGC Proceedings (1977-2023)

Seed dormancy is a common feature of the majority of forage species. It usually causes problems both to the grower and the seed analyst. Many methods have been developed to break dormant seed over the time, and efficacy of a method usually varies with species and cultivars. The objective of this paper is to review and summarise important methods used for seed dormancy breaking in forage legume and grass species, and the mechanisms involved.

Restoring North America’S Sagebrush Steppe Ecosystem Using Seed Enhancement Technologies, Matthew D. Madsen, Kirk W. Davies, Chad S. Boyd, Jay D. Kerby, Daniel L. Carter, Tony J. Svejcar

IGC Proceedings (1977-2023)

Rangelands occupy over a third of global land area, and in many cases are in less than optimum condition as a result of past land use, catastrophic wildfire and other disturbance, invasive species, or climate change. Often the only means of restoring these lands involves seeding desirable species, yet there are few cost effective seeding technologies, especially for the more arid rangeland types. The inability to consistently establish desired plants from seed may indicate that the seeding technologies being used are not successful in addressing the primary sources of mortality in the progression from seed to established plant. Seed enhancement …

Comprehensive Evaluation Of Wild Elymus L. Germplasm In Inner Mongolia, Juan Qi, Wen-Xia Cao, Ting Jiao, Xiao-Peng Pu, Wei-Hong Yan

IGC Proceedings (1977-2023)

Grassland degradation is increasing in severity and is an important global issue in the 21st century. Increasing research is being conducted on how to solve these problems (Niu and Jiang 2004). Restoration and revegetation of degraded grassland and the establishment of artificial pastures are important in addressing degradation. Successful restoration requires the identification of species and seed sources that are adapted to the ecological conditions of the restoration site. Elymus L. is a large genus that contains about 150 species distributed across a wide range of ecological sites across temperate and subtropical regions of the world (Dewey 1984; Love 1984). …

Fatty Acid Analysis Of The Transgenic Tobacco Expressing A Delta 6-Desaturase Gene From Microula Sikkimensis, Shujuan Wu, Lijing Zhang, Xiaolong Chen, Xiumei Miao, Decao Niu, Hua Fu

IGC Proceedings (1977-2023)

γ-Linolenic acid (GLA, 18:3^{Δ6, 9, 12}) and octadecatetraenoic acid (OTA, 18:4^{Δ6, 9, 12, 15}) are important polyunsaturated fatty acids (PUFAs), which have been proved to be benefit for human health (Fan and Chapkin 1998; Whelan 2009). Currently, fish are the predominant source of PUFAs. However, with the growth of world’s population and the more nutrition requirements, fishery resources are shrinking. Alternative sources of PUFAs are being investigated (Truksa et al. 2009). The major oil crops do not contain GLA and OTA, only several plant species contain these important fatty acids in their leaf lipids and …
