Effects of D-ring modified gibberellins on flowering and growth in lolium temulentum
摘要:
The modified gibberellins, 16-methyl-16,17-dihydro-GA(5), 16,17-methano-16,17-dihydro-Gh(5), 16,17-methano-16,17-dihydro-GA(3) and several halogenated derivatives of 16,17-methano-16,17-dihydro-GA(3) and GA(5) were prepared and tested for bioregulating properties in Lolium temulentum. The effects ranged from the promotion of both stem elongation and flowering, the promotion of flowering but not elongation, and vice versa, the inhibition of stem elongation combined with the promotion of flowering, and the inhibition of both.
