EFFECTS OF GIBBERELLIC ACID, ACETYLTHIPROLINE, AND A MIXTURE OF AMINO ACIDS + SHORT-CHAIN PEPTIDES ON SCALLION YIELD

摘要

Scallion sets were soaked for 14 hours in aqueous solutions of gibberellic acid 3 (GA)(5, 10, 20, 30 mg-L~(-1)), acetylthioproline (AP)(100, 200, 300, and 400 mg-L~(-1)), and a glycine-rich commercial complex of ammo acids and short-chain peptides (APC)(1, 2, 3, and 4 g-L~(-1)). The same AP, APC, and GA rates were sprayed on the resulting plants 15 and 30 days after sprouting. As compared to non-treated control plants, scallion yield was significantly higher in scallions treated with GA, AP, and APC,regardless of rate. The highest yields were obtained with APC at the rate of 3 g.L~(-1), AP at the rate of 300 mg L~(-1) and GA at the rates of 20-30 mg-L~(-1).
