Apple Tree Responses To Deficit Irrigation Combined With Periodic Applications Of Particle Film Or Abscisic Acid, Khalid M. Al-Absi, Douglas D. Archbold
Apple Tree Responses To Deficit Irrigation Combined With Periodic Applications Of Particle Film Or Abscisic Acid, Khalid M. Al-Absi, Douglas D. Archbold
Horticulture Faculty Publications
The objective of this study was to determine if the application of two antitranspirant compounds would moderate water deficit stress effects on physiological responses of “Granny Smith”, “Royal Gala” and “Golden Delicious” apple (Malus domestica Borkh.) trees on MM106 rootstock that occur during deficit irrigation. Uniform trees were grown in pots under water supply regimes of 30%, 60%, and 80% depletion of available water (DAW) before irrigation to runoff and received applications of kaolin particle film (PF) or abscisic acid (ABA) at 0, 30 and 60 days. At 120 days, genotype and deficit irrigation affected nearly all leaf traits, …
Role Of Fatty Acid Omega-Hydroxylase 1 And Abscisic Acid In Potato Tuber Suberin Formation, Meg Haggitt
Role Of Fatty Acid Omega-Hydroxylase 1 And Abscisic Acid In Potato Tuber Suberin Formation, Meg Haggitt
Electronic Thesis and Dissertation Repository
Suberin is a complex biopolymer composed of two distinct but covalently-linked domains. The first domain is composed of polymerized phenolic monomers, whereas the second domain is predominately fatty acid derivatives esterified with glycerol. Deposited in specialized cells during development or in response to abiotic stress, suberin functions as a barrier to water loss and pathogen attack. In potato, more than 65% of suberin monomers undergo ω-hydroxylation, representing a major class of fatty acids in the final biopolymer. The ω-hydroxylation reaction is catalyzed by Cytochrome P450 (CYP) proteins, of which few have been characterized to date. In 2009, CYP86A33 from potato …
Effects Of Abscisic Acid (Aba) On Germination Rate Of Three Rangeland Species, Turmandakh Badrakh
Effects Of Abscisic Acid (Aba) On Germination Rate Of Three Rangeland Species, Turmandakh Badrakh
Theses and Dissertations
Seeds sown in the fall to restore sagebrush (Artemisia spp.) steppe plant communities could experience high mortality when they germinate and seedlings freeze during the winter. Delaying germination until the risk of frost is past could increase seedling survival. We evaluated the use of abscisic acid (ABA) to delay germination of Elymus elymoides, Pseudoroegneria spicata, and Linum perenne. The following treatments were applied: uncoated seed, seed coated with ABA at 2.2, 4.4, 8.8, 13.2, and 17.6 g of active ingredient kg-1 of seed, and seed coated with no ABA. The influence of seed treatments on germination were tested at five …
A Bioinformatics Approach To Addressing The Responses Of Rice Aleurone Cells To Hormones Abscisic Acid And Gibberellic Acid, Kenneth Arthur Watanabe
A Bioinformatics Approach To Addressing The Responses Of Rice Aleurone Cells To Hormones Abscisic Acid And Gibberellic Acid, Kenneth Arthur Watanabe
UNLV Theses, Dissertations, Professional Papers, and Capstones
The hormone abscisic acid (ABA) is biosynthesized by higher plants in response to various abiotic stresses such as drought and antagonizes the growth and germination-promoting hormone gibberellic acid (GA). The seed is a model system for studying desiccation tolerance and germination. The thin layer of cells surrounding the seed, the aleurone layer, plays a direct role in seed germination and an indirect role in desiccation tolerance. The goal of my research is to address the molecular mechanism underlying the responses of rice aleurone cells to ABA and GA, by taking a genomics approach. An accurate and complete annotation of the …
Relationships Between Some Endogenous Signal Compounds And The Antioxidantsystem In Response To Chilling Stress In Maize (Zea Mays L.) Seedlings, Nevzat Esi̇m, Ökkeş Atici
Relationships Between Some Endogenous Signal Compounds And The Antioxidantsystem In Response To Chilling Stress In Maize (Zea Mays L.) Seedlings, Nevzat Esi̇m, Ökkeş Atici
Turkish Journal of Botany
This study investigated the correlation between endogenous levels of some signal compounds [nitric oxide (NO), salicylic acid (SA), abscisic acid (ABA)] and the antioxidant system in response to chilling stress in maize (Zea mays L.). Seedlings grown for 12 or 19 days under normal conditions (24/20 °C) were exposed to chilling stress (10/7 °C) for 2 days. The levels of NO, SA, ABA, hydrogen peroxide (H2O2), superoxide anion (O2.-), and malondialdehyde (MDA) were determined in leaves of seedlings harvested on day 14 and day 21. In the same seedlings, the activities of superoxide dismutase (SOD), peroxidase (POX), catalase (CAT), and …
