Role of methyl jasmonate and salicylic acid applications on bloom delay, flowering and fruiting of ‘Elberta’ Peach
Peach (Prunus persica L. Batsch.) is produced in most areas of Iran, where flowering is hindered by temperature. Using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. The objective of this study was to determine the effects of methyl jasmonate (MJ) and salicylic acid (SA) on peach bloom delay and yield. This study evaluated the applications of MJ 0 (contro...
متن کاملEffects of gibberellic acid on primary terpenoids and delta-tetrahydrocannabinol in Cannabis sativa at flowering stage.
Plants synthesize an astonishing diversity of isoprenoids, some of which play essential roles in photosynthesis, respiration, and the regulation of growth and development. Two independent pathways for the biosynthesis of isoprenoid precursors coexist within the plant cell: the cytosolic mevalonic acid (MVA) pathway and the plastidial methylerythritol phosphate (MEP) pathway. However, little is ...
متن کاملMeasurement of Indole-3-Acetic Acid in Peach Fruits (Prunus persica L. Batsch cv Redhaven) during Development.
The amount of indole-3-acetic acid (IAA) was measured in peach fruits by gas chromatography-mass spectrometry-selective ion monitoring using an isotope dilution assay with [(13)C(6)]IAA as an internal standard throughout the growing season. Ethylene evolution of the fruit was also measured. IAA levels were 25 nanograms per gram fresh weight, 18 days after anthesis. Both IAA levels and rates of ...
متن کاملThe DELLA-CONSTANS Transcription Factor Cascade Integrates Gibberellic Acid and Photoperiod Signaling to Regulate Flowering.
Gibberellin (GA) and photoperiod pathways have recently been demonstrated to collaboratively modulate flowering under long days (LDs). However, the molecular mechanisms underlying this collaboration remain largely unclear. In this study, we found that GA-induced expression of FLOWERING LOCUS T (FT) under LDs was dependent on CONSTANS (CO), a critical transcription factor positively involved in ...
متن کاملAn Effect of Gibberellic Acid on the Flowering of Xanthium, a Short Day Plant.
vinelanidii. The related compounds tested, phenoxyacetic acid, phenylpropionic acid, orthoand parachlorophenoxyacetic acids, inhibited the test organism to lesser degrees. Protection from the inhibition produced by 2 x 10-2 MI phenoxyacetic acid and phenylpropionic acid was afforded by molar ratios of 1: 1 and 2: 1 respectively', magnesium to the agents. Considerable protection, though not comp...
