Genetic Analysis Of Kafirins And Their Phenotypic Correlations With Feed Quality Traits, In Vitro Digestibility, And Seed Weight In Grain Sorghum, C. Hicks, S. R. Bean, G. L. Lookhart, Jeffrey F. Pedersen, K. D. Kofoid, M. R. Tuinstra

Department of Agronomy and Horticulture: Faculty Publications

Twenty-three entries of grain sorghum (Sorghum bicolor (L.) Moench), including eight inbred lines (five males and three females) and 15 hybrids, were evaluated to determine the proportion of γ, αII, and β-αI-kafirins and their association with contents of crude protein, fat, and starch; protein digestibility; in vitro dry matter disappearance; and seed weight. The male lines included three normal-seeded lines (TX2737, TX435, and P954063) and two large-seeded lines (Eastin1 and PL-1). Female lines consisted of three common U.S. seed parent lines (Wheatland, Redlan, and SA3042). The lines and their hybrids were grown under dryland conditions at two locations in …

Seed Physiology, Production & Technology: Germination, Emergence, And Yield Of 20 Plant-Color, Seed-Color Near-Isogenic Lines Of Grain Sorghum, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Although there is growing demand for sorghum [Sorghum bicolor (L.) Moench] with white seed and tan plant color, there is limited information on the overall agronomic fitness of sorghum with these characters. A set of experiments was conducted to evaluate the combined effects of plant color and seed color on sorghum germination, emergence, and agronomic performance. Twenty near-isogenic lines with red seed/tan plant (RT), red seed/purple plant (RP), white seed/ tan plant (WT), white seed/purple plant (WP) phenotypes were tested under field and laboratory conditions. Plant color X seed color interactions were not significant. Purple plant color phenotypes had higher …

The Origin Of The 'Wild Orchards' Of Central Anatolia, Henk Woldring, Rene Cappers

Turkish Journal of Botany

Palynological investigations have revealed that the deforestation of Central Anatolia started c. 4000 BP. At present, most of the land is cultivated and only small patches of woodland occur in remote mountain areas. These woodlands are dominated by deciduous oaks ( Quercus L. spp.) or locally by junipers ( Juniperus L. spp.). A pattern of scattered fruit trees, the so-called wild orchards, characterizes the cultivated fields. Another type of arboreal vegetation is found on isolated rock outcrops in the fields. Surveys of the vegetation types show that oaks are uncommon among the fields and on the rock outcrops. By contrast, …

Pollen Flora Of Pakistan - Xxviii: Resedaceae, Anjum Perveen, Mohammad Qaiser

Turkish Journal of Botany

The pollen morphology of 4 species belonging to the 3 genera of the family Resedaceae was investigated using a light microscope and scanning microscope. Pollen grains usually radially symmetrical, isopolar, sub-prolate, rarely prolates pheroidal, tricolpate or tricolporate. Tectum reticulate. However, apertural type and pollen shape are the most significant pollen characters for delimiting the genera. On the basis of apertural types 2 distinct pollen types are recognized, namely, I: Tricolpate-type and II: Tricolporate-type.

Heavy Metal Accumulation And Detoxification Mechanisms In Plants, Abdul R. Memon, Di̇ğdem Aktoprakligi̇l, Ayli̇n Özdemi̇r, Anastassiia Vertii

Turkish Journal of Botany

Toxic metal contamination of soil, aqueous waste streams and groundwater causes major environmental and human health problems. The most commonly used methods for dealing with heavy metal pollution are still extremely costly. Phytoremediation is the use of plants to extract, sequester and/or detoxify pollutants and is a new and powerful technique for environmental clean-up. Plants are ideal agents for soil and water remediation because of their unique genetic, biochemical and physiological properties. Considerable advances have been made in recent decades in developing endemic or genetically engineered plants for the remediation of environmental clean-up. In the present review, current knowledge about …

A Study On The Autecology Of Reseda Lutea L. (Resedaceae) Distributed In Western Anatolia, Yunus Doğan

Turkish Journal of Botany

The aim of this study was to determine the autecological characteristics of Reseda lutea L. (Resedaceae) distributed in Western Anatolia. The chemical and physical analysis was carried out on soil and plant samples collected from 54 different localities in Western Anatolia. The results show that the plant generally prefers sandy-loam and sandy-clayey-loam textural soils, with a slightly alkaline or medium alkaline pH. They prefer non-saline, calcareous soils which are poor in potassium and phosphorus, but the nitrogen content of the soils was found to vary greatly. The soil and plant analysis results were evaluated statistically and correlations were established.

The Low Above-Zero Temperature Effect In The Zone Of Roots On Nitrate Reductase Activity In Pea Organs In The Process Of Vegetating, G. G. Vasilieva, N. V. Mironova, A. K. Glyanko

Turkish Journal of Botany

Experiments with pea (Pisum sativum L.) cv. Marat) in a phytotron chamber showed that the process of nitrate assimilation in pea organs depends on temperature in the zone of the roots and on the phase of development of the plants. The potential of tissues of different organs for nitrate reduction was compared to the amount of nitrates which they accumalated. A decrease in nitrate reductase activity during certain phases of development is assumed to be related to the process of formation and functioning of nodules.

Using Upper Boundary Constraints To Quantify Competitive Response Of Desert Annuals, Laura M. Lessin, Andrew R. Dyer, Deborah E. Goldberg

Faculty Publications

Using a target-neighborhood approach with six annual dicot species in the Negev Desert of Israel, we tested whether neighborhood biomass constrained the upper limit of plant performance and if the slope of the upper boundary was correlated to species trait means, such as relative growth rate (RGR) and seed mass. Target individuals were measured in early spring and then collected at the onset of the dry season along with all naturally occurring neighbors within a 5-cm radius of the target. Using a minimum of 50 samples for each of the six target species, we found no significant relationships between target …

Inventory Of Parks Division Lands For Threatened And Endangered Species Habitats And Exemplary Natural Communities, Steven B. Rolfsmeier

In addition, the Program maintains a statewide database on natural communities and rare and imperiled species. This information is used to inform conservation decision-making, including land management decisions, with a goal of conserving Nebraska’s flora and fauna, our natural legacy. The two main objectives of this inventory project were first to improve the Nebraska Game and Parks Commission’s knowledge of threatened and endangered species and their potential habitat on Parks …

Aquatic Plants Of Nebraska, Michael P. Gutzmer, Robert B. Kaul

University of Nebraska State Museum: Programs Information

More than 100 species of aquatic plants grow in Nebraska. Some are entirely submersed for their whole lives, others produce floating leaves and flowers, and still others stand upright, with only their lower stems in water. Examples of these are shown here in this publication.

Vigorous and diverse colonies of aquatic plants are usually a sign of healthy and stable aquatic environments. In fact, the plants themselves stabilize the shorelines, underwater soils, and water chemistry. Waters rich with aquatic plants are rich with aquatic animals and waterfowl, which find cover, breeding habitat, and abundant food. Non-alkaline waters have more aquatic …

Using The Green Flagellate Euglena Gracilis Klebs As Physiological Dosimeter: Is A Long-Term Bioassay More Significant Than A Short-Term One?, Roman A. Danilov, Nils C. A. Ekelund

Turkish Journal of Botany

The use of short-term tests with E. gracilis Klebs in order to assess toxicity cannot be viewed as absolutely preferable. At least in the case with wastewater from the pulp and paper industry, 7 day-tests could lead to more explanatory and significant results.

Recognition Of Bromus Richardsonii And B. Ciliatus: Evidence From Morphology, Cytology, And Dna Fingerprinting (Poaceae: Bromeae), Paul M. Peterson, Jacques Cayouette, Yasas S. N. Ferdinandez, Bruce Coulman, Ralph E. Chapman

Aliso: A Journal of Systematic and Floristic Botany

Since our goal was to determine characteristic differences between Bromus richardsonii and B. ciliates, a discriminate analysis (DA), principal components analysis (PCA), multidimensional scaling (MDS), bivariate analysis, and an amplified fragment length polymorphisms (AFLP) analysis were undertaken on 93 herbarium specimens and 31 field-collected populations. A cytological survey of B. ciliates, B. richardsonii, and B. mucroglumis confirm previous reports that the first species is diploid (2n = 14) and the latter two are tetraploid (2n = 28). All taxa were correctly classified in the DA and important characters for each of the species were identified. Bromus …

Insertion Of An Antimicrobial Gene Into Agrobacterium And Its Further Use In Transforming Tobacco, Ekrem Gürel

Turkish Journal of Botany

In the present work, we first describe the transfer of a novel gene, designated 5W, into the LBA4404 Agrobacterium tumefaciens strain using pPCV91 plasmid through a triparental mating system. The 5W gene was recently isolated from macadamia, a native nut tree species of Australia, and has been shown to have an antimicrobial effect against certain fungi in vitro. Secondly, this gene was tranferred into tobacco (Nicotiana tabacum cv. Xhantii) using leaf explants to develop a system which could then be used for transferring this antimicrobial peptide into sunflower cultivars.

Pollen Flora Of Pakistan-Xxxi Capparidaceae, Anjum Perveen, Mohammad Qaiser

Turkish Journal of Botany

The pollen morphology of 14 species belonging to seven genera viz., Cadaba Forssk., Capparis L., Cleome L., Dipterygium Decaisne, Gynandropsis DC., Maerua Forssk., of the family Capparidaceae, was investigated using a light microscope and scanning microscope. The results confirm the eurypalynous nature of the family. However, palynology is significantly helpful at the specific level. Pollen grains usually radially symmetrical, isopolar, sub-prolate to prolate, generally tricolporate, often tetra-colporate. Tectum generally spinulose, or striate-rugulate, or rugulate-reticulate often sub-psilate.

The Effect Of Glycinebetaine On The Heat Stability Of Photosynthetic Reactions In Thylakoid Membranes, Yagut M. Allakhverdieva, Mahir D. Mamedov, Ralphreed A. Gasanov

Turkish Journal of Botany

Heat inactivation of various photosynthetic electron transport reactions were investigated in the presence/absence of glycinebetaine (betaine) in unstacked thylakoid membranes from spinach. The activity of Photosystem II (PS II) is more sensitive to heat than that of Cytochrome bf (cyt.bf) and Photosytem I (PS I) complexes. The data obtained clearly demonstrated the protection of PS II and PS I electron transfer by betaine under high temperatures. The phenomena observed are probably related to the stabilization of the higher-order structures of PS II and PS I by betaine.
