gibberellic acid การใช้

• Repressor of GA responses and involved in gibberellic acid mediated signaling.
• Gibberellic acid slows postharvest degreening of  Oroblanco citrus fruits.
• They used several combinations of treatments which included chilling, gibberellic acid, and mechanical scarification.
• Gibberellic acid is a dihydroxylated gibberellin.
• The mutants could not produce full-grown tendrils, it seems that gibberellic acid converts grapevine flower buds into tendrils.
• Examples of plant hormones that are subjected to ion trapping are abscisic acid, gibberellic acid and retinoic acid.
• Gibberellic acid controls cellular differentiation, so its block is needed for maintenance of meristematic cells and for their proliferation.
• This drought tolerance mechanism is stimulated by a decrease in gibberellic acid concentration and an increase in abscisic acid concentration.
• Gibberellic acid, the plant growth hormone, is available from a mail-order nursery that also sells small, inexpensive trees and shrubs.
• There he studied under E . J . Corey and completed his thesis on the total synthesis of gibberellic acid.
• The fruit's size has not been shown to increase appreciably by girdling the vines or by applying gibberellic acid when the berries set.
• The 19-carbon gibberellins, such as gibberellic acid, have lost carbon 20 and, in place, possess a five-member lactone bridge that links carbons 4 and 10.
• But because farmers now spray trees with gibberellic acid and another compound called 2, 4-D to delay maturity, the San Joaquin season stretches into April.
• Gibberellic acid has also been used for the same purpose, but it is harder to acquire than colloidal silver and can be difficult to dissolve into solution.
• Beside cytokinin and auxin, " R . fascians " acts on other hormones : in particular, it can block abscisic acid and gibberellic acid synthesis in infected plants.
• :As a side-note ( kind of ), the use of a gibberellic acid ( GA3 ) supplement can aid in the germination of older dormant seeds that would otherwise have difficulty germinating.
• Gibberellic acid is sometimes used in laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain Creston valleys, it is also used as a growth replicator in the cherry industry.
• With the availability of molecular genetics in Arabidopsis and rice the mutant genes responsible ( " reduced height ( rht ) ", " gibberellin insensitive ( gai1 ) " and " slender rice ( slr1 ) " ) have been cloned and identified as cellular signalling components of gibberellic acid, a phytohormone involved in regulating stem growth via its effect on cell division.
