Improving essential oil content and yield of ajowan organs under water stress by application of salicylic acid and abscisic acid
This research was carried out in 2014 and 2015 to assess the effects of salicylic acid (SA)(0 and 1 mM) and abscisic acid (ABA) (0 and 50 µM) on essential oil content and yield ofajowan (Carum copticum L.) organs under different irrigation intervals (I1, I2, I3, I4: irrigationafter 70, 100, 130 and 160 mm evaporation, respectively). Plants were sprayed by SA and ABAat vegetative and reproductiv...
متن کاملPattern of Variations in Abscisic Acid Content in Suspensors, Embryos, and Integuments of Developing Phaseolus coccineus Seeds.
Free abscisic acid (ABA) content in suspensors, embryos, and integuments was determined during seed development of Phaseolus coccineus. A highly specific and sensitive solid-phase radioimmunoassay based on a monocional antibody raised against free (S)-ABA was used for ABA quantification. Very small amounts of ABA were detected in the suspensor during initial stages of development; later two pea...
متن کاملAbscisic Acid Accumulation in Developing Seeds of Phaseolus vulgaris L.
Free and bound abscisic acid (ABA) in the pod, seed coat, and embryo were determined separately throughout seed development of Phaseolus vulgaris L. cv. ;Taylor's Horticultural.' An internal standard method of gas-liquid chromatography was used for ABA quantification. In the embryo, two peaks of free ABA occurred at days 22 (1.18 micrograms per gram or 5.5 micromolar) and 28 (1.74 micrograms pe...
متن کاملLeaf Abscisic Acid Accumulation in Response To Substrate Water Content: Linking Leaf Gas Exchange Regulation with Leaf Abscisic Acid Concentration
Quantitative differences in leaf abscisic acid (ABAL) among four cultivars of red maple (Acer rubrum L.) and one freeman maple (Acer ×freemanii E. Murray) cultivar were investigated. This study tested the hypothesis that ABAL concentration can be used to compare the effects of water stress on the gas exchange response of fi ve different maple genotypes, including four red maple cultivars [‘Summ...
متن کامل(+)-abscisic Acid content of spinach in relation to photoperiod and water stress.
Levels of (+)-abscisic acid present in the long-day plant spinach (Spinacia oleracea L., cv. Savoy Hybrid 612) grown under different photoperiodic regimes were measured in purified extracts by optical rotary dispersion. When plants were transferred from short to long days, the abscisic acid content increased 2- to 3-fold. This rise in the level of abscisic acid took place during the 1st long da...
