Physiological And Biochemical Responses Of Maize (Zea Mays L.) Cultivars Under Salinity Stress, Nosheen Iftikhar, Shagufta Perveen, Baber Ali, Muhammad Hamzah Saleem, Mohammad Khalid Al-Sadoon

Turkish Journal of Agriculture and Forestry

Salt stress is a serious threatening factor for cereal crops such as maize (Zea mays L.) by affecting their growth and development. In the current era, the requirement for staple crops is increasing, so it is important to screen out salt-tolerant genotypes. For this purpose, a pot experiment was designed within three replications on ten different genotypes of the maize. The plants were planted in plastic pots and salt stress (0, 40, 70, 100 mM) was maintained. The salt stress induced a noticeable reduction in plant growth traits (shoot length, root length, shoot, root fresh and dry weight, and leaf …

Evaluation Of Arginine Decarboxylase (Fvadc) And Spermidine Synthase (Fvspds) Genes Of Woodland Strawberry (Fragaria Vesca L.) In Nicotiana Tabacum, Ákos Mendel, Erzsebet Kiss

Turkish Journal of Agriculture and Forestry

A comparative analysis was performed under in vitro conditions using Nicotiana tabacum lines overexpressing the genes of arginine decarboxylase (FvADC) and spermidine synthase (FvSPDS) enzymes. The transgenic and native lines were tested under controlled conditions and exposed to long-term treatment of arginine (150 mg/L), putrescine (10 mg/L), and spermidine (10 mg/L). Chlorophyll and lignin contents of the samples were measured spectrophotometrically, while proline, putrescine, spermidine, and spermine contents were determined using high-performance liquid chromatography methods. The experimental results showed that the arginine decarboxylase enzyme affects polyamine metabolism. As it is involved in several other biosynthetic pathways, this effect is significant …

Local Organic And Inorganic Amendments To Improve Table Grape Production In Mediterranean Vineyards Of Southern Türkiye, Semi̇h Tangolar, Simone Priori, Serpi̇l Tangolar, Meti̇n Turan, Erhan Akça

Turkish Journal of Agriculture and Forestry

In the Mediterranean Region, calcareous soils are generally considered to be of low fertility. The use of large amounts of chemicals and irrigation to compensate for low productivity reduces the producer’s net profit and degrades physical and chemical properties of the soils. As a result, the selection of adaptable genotypes is important in agriculturally limited lands. Grapevine is one of the leading crops in the Mediterranean Basin due to its high tolerance to abiotic conditions. However, the fact that the grapevine grows in extreme soils does not mean that such crop does not respond to a good nutritional program, especially …

Effects Of Nutrient Solution Strength, Pgpb, And Mycorrhizal Inoculation On Growth,Yield, And Quality Of Strawberry, Masoud Haghshenas, Sander H. Van Delden, Mohammad Javad Nazarideljou

Turkish Journal of Agriculture and Forestry

Strawberry (Fragaria × ananassa Duch) cultivation is not without difficulty since its root environment is sensitive to many biotic and abiotic stresses. In addition, production is often phosphate limited, even at relatively high phosphorus levels, as the high fruit yields greatly exceed the capacity of the phosphorus supply by the root system. Arbuscular mycorrhizal fungi (AMF), plant growth promoting bacteria (PGPB), and combinations of both are known to mitigate stress and enhance nutrient uptake, particularly phosphorus. Therefore, we studied the effects of AMF (Glomus mosseae, and Glomus intraradices), PGPB (Azospirillum lipoferum DSM1691, and Pseudomonas fluorescens DSM 50090), and their combinations …

Turkish Journal of Agriculture and Forestry

Using a bioinformatics approach to identify binding pockets between proteins is a preferable method before modifying the genome to delineate host interactions with viruses. Based on extensive proteomics data in numerous databases, several interaction prediction methods are available to identify binding sites between viruses and hosts at the individual residue level, but little is known about the interaction prediction strategy for plant viruses. Begomoviruses, belonging to the family Geminiviridae, constitute a group of circular single-stranded (ss) DNA viruses that encode multifunctional proteins responsible for viral replication, causing severe diseases in multiple host plants. These viruses usually escape through plant defense …

Turkish Journal of Agriculture and Forestry

Organic carbon performs essential functions in soils. Soils act as sources or sinks of atmospheric organic carbon. Agricultural management influences soil organic carbon, impacting climate change. One of the crops most vulnerable to climate change is coffee. Brazil is the world's largest coffee producer, with a predominance of management under a conventional system, with sloping terrain and the absence of conservationist practices. The absence of conservationist practices results in an increase in soil loss rates due to water management and carbon emissions, as well as a reduction in coffee production. This paper aimed to estimate soil and organic carbon losses …

An Evaluation Of Sonderegger Pine Morphology, Kelsey Denise Shoemaker

Master's Theses

Sonderegger pine (Pinus x sondereggeri H.H. Chapm.), the naturally occurring hybrid of longleaf (Pinus palustris Mill.) and loblolly pine (Pinus taeda L.), is considered a producer of poor-quality wood due to observations of stem forking and a high number of large-diameter branches at maturity. Because landowners generally decline planting Sonderegger pine seedlings, nursery workers cull putative hybrids from longleaf pine seedling stock during lifting and processing. However, over the past 100 years, very few studies have quantified stem quality of Sonderegger pine. To gain a better understanding of the early growth and development of Sonderegger pine, evaluations of height, diameter …

Sustainability In Action: Green Infrastructure As A Marker Of Sustainable Urban Development, Brianna Nadine Santiago

FIU Undergraduate Research Journal

The current form and pace of urbanization is an ongoing threat to sustainable urban development. As these problems span social, environmental, and economic realms, it is imperative that any proposed solution is able to address these problems holistically. Although a number of silver-bullet solutions such as electric vehicle adoption have been introduced, they do not respond to the problems with an integrated approach. Tackling this problem will require a solution that can be changed and applied on a case-by-case basis. Therefore, the development of green infrastructure is the most efficient solution when responding to the problems threatening urban sustainability. The …

The Need For A Chainsaw Safety Training Program For Female Forest Landowners, Patrick Hiesl, Janet Steele, Susan T. Guynn

The Journal of Extension

Female forest landowners (FFLO) are increasing in numbers but have been marginalized in technical training programs in the past. We conducted chainsaw safety training programs geared towards FFLO and compared program evaluation results with results from male-dominated chainsaw training workshops. FFLO are limited in their technical knowledge at the beginning of a workshop, are more likely to own different types of chainsaws than male participants, and generally liked having a women-only workshop. The takeaway is that FFLO strive in a women-only environment and that more women-focused extension training programs are needed to provide with a safe and inclusive learning environment.

The Biltmore Forest School And The Establishment Of Forestry Education In America, Dan Barry Croom

Journal of Research in Technical Careers

The Biltmore Forest School, despite its unusual existence within the affluent Biltmore Estate, played a crucial role in the early 20th-century American forestry movement. Founded by Carl A. Schenck and supported by George Vanderbilt II, the school aimed to educate foresters and promote sustainable forest management. However, many aspects of the Biltmore experiment failed due to the new and untested nature of forestry science in America. This experiment exposed a fundamental divide in forestry education, with Gifford Pinchot advocating for conservation-centered teaching while Schenck believed in the economic viability of lumber production. Ultimately, the Biltmore Forest School offered valuable vocational …

Quemando Leña En Guatemala: Salud, Sostenibilidad Y Costumbres, Sydney Underhill

World Languages and Cultures Senior Capstones

In the Central American country of Guatemala, firewood is an important fuel source. Eighty-eight percent of households in rural areas use wood stoves and open fires to cook and heat their homes. This tradition has fundamental roots in the culture and customs of Guatemala. Unfortunately, these methods contribute to air pollution. Consequently, it also results in smoke inhalation, which causes health problems. Additionally, the massive agriculture of other crops decreases the amount of firewood available to these households, affecting the sustainability of the resource. Some communities resist changing their use of firewood due to the profound nature that firewood holds …

Environmental Factors Associated With Triploid Aspen Occurrence In Intermountain West Landscapes, James A. Walton

All Graduate Theses and Dissertations, Fall 2023 to Present

Polyploidy is common among plants and can contribute to physiological and morphological differences, altering how plants respond to environmental changes, promoting genetic diversification and even species radiation. Quaking aspen (Populus tremuloides), a keystone species associated with high plant and animal diversity is frequently found in mixed diploid/triploid populations in the Intermountain West. Triploid aspen carries an extra chromosomal copy, whereas the diploid type contains two chromosomal copies. High mortality rates and widespread population declines in aspen are of increasing concern in the Intermountain West, and often ascribed to changing climates and drought stress events. The goal of this …

Winter Roost Selection Of Eastern Red Bats And Impacts Of Non-Growing Season Prescribed Fire On Foraging Activity Of Forest Roosting Bats In Tennessee, Ashley D. Epstein

Masters Theses

With an increase in wind energy development and continued deforestation and habitat degradation, eastern red bats (Lasiurus borealis; LABO) and other migratory foliage roosting bats (hoary bat [Lasiurus cinereus; LACI], silver-haired bat [Lasionycteris noctivagans; LANO]) are at risk of severe population declines, potentially leading to the need for protection under the Endangered Species Act. While studies have been done examining the ecology of these species, there is still a lack of research on winter roosting and foraging behaviors. This research aims to fill some of those knowledge gaps by 1) Examining roost use (i.e., trees vs. litter) …

Evaluation Of Regression Methods And Competition Indices In Characterizing Height-Diameter Relationships For Temperate And Pantropical Tree Species, Sakar Jha

Masters Theses

Height-diameter relationship models, denoted as H-D models, have important applications in sustainable forest management which include studying the vertical structure of a forest stand, understanding the habitat heterogeneity for wildlife niches, analyzing the growth rate pattern for making decisions regarding silvicultural treatments. Compared to monocultures, characterizing allometric relationships for uneven-aged, mixed-species forests, especially tropical forests, is more challenging and has historically received less attention. Modelling how the competitive interactions between trees of varying sizes and multiple species affects these relationships adds a high degree of complexity. In this study, five regression methods and five distance-independent competition indices were evaluated for …

Callaghan, Mariana Cárdenas, Matthew W. Chmielewski, Nicole J. Fenton, Hannah Holland-Moritz, Samantha Hopkins, Mélanie Jean, Bier Ekaphan Kraichak, Zoë Lindo, Amelia Merced, Tobi Oke, Daniel Stanton, Julia E. Stuart, Daniel Tucker, Kirsten K. Coe

Michigan Tech Publications, Part 2

Bryophytes, including the lineages of mosses, liverworts, and hornworts, are the second-largest photoautotroph group on Earth. Recent work across terrestrial ecosystems has highlighted how bryophytes retain and control water, fix substantial amounts of carbon (C), and contribute to nitrogen (N) cycles in forests (boreal, temperate, and tropical), tundra, peatlands, grasslands, and deserts. Understanding how changing climate affects bryophyte contributions to global cycles in different ecosystems is of primary importance. However, because of their small physical size, bryophytes have been largely ignored in research on water, C, and N cycles at global scales. Here, we review the literature on how bryophytes …
