ABA Levels and Sensitivity in Developing Wheat Embryos of Sprouting Resistant and Susceptible Cultivars.
A sprouting-resistant and a sprouting-susceptible wheat cultivar were utilized to examine the role of ABA levels and sensitivity responses in wheat embryonic germination. Endogenous embryonic ABA levels were measured in both cultivars throughout grain maturation utilizing a new and sensitive ABA immunoassay. Embryonic ABA levels of each cultivar were similar with the sprouting-susceptible culti...
متن کاملResponse of cultivars of soybean to synthetic abscisic Acid.
This paper describes work to determine whether soybean cultivars differ in their physiological response to applied abscisic acid. ABA is a naturally occurring plant hormone that affects a number of physiological processes, including leaf abscission, leaf senescence, seed germination, bud dormancy, flowering, and tuberization (4). Usually, ABA is applied in various concentrations to whole plants...
متن کاملIsolation and characterization of Viviparous-1 genes in wheat cultivars with distinct ABA sensitivity and pre-harvest sprouting tolerance.
Pre-harvest sprouting (PHS) of wheat reduces the quality and economic value of grain, and increasing PHS tolerance is one of the most important traits in wheat breeding. Two new Vp-1B alleles related to PHS tolerance were identified on the 3BL chromosome of bread wheat and were designated Vp-1Bb and Vp-1Bc. Sequence analysis showed that Vp-1Bb has a 193 bp insertion and Vp-1Bc has a 83 bp delet...
متن کاملSalt Sensitivity of Two Wheat Cultivars at Different Growth Stages
To determine salt sensitivity for wheat at various growth stages, a factorial experiment arranged as randomized complete block design was conducted in the ambient environment at the National Salinity Research Center, Yazd, Iran. Treatment were two cultivars of wheat (Kavir & Roshan) and salinity imposed at emergence, tillering, stem elongation, spike emergence and one week after anthesis. A con...
متن کاملThe 7 ’ - Methyl Group of Abscisic Acid I s Critical for Biological Activity in Wheat Embryo Germination ’
Wheat (Triticum aestivum 1.) embryo germination is inhibited by natural (S)-(+)-abscisic acid (ABA). In this report we have determined critical structural features of the ABA molecule, particularly the methyl and ketone groups of the ABA ring, required for inhibitory activity. To examine the ring residues a series of new optically active ABA analogs have been synthesized in which the 4’-keto, 7...
