落葉劑與剪葉處理對於大豆成熟期、產量及品質之影響

Abstract

本試驗於大豆R6(full seed)時期以三種不同濃度(1D, 2D, 3D)落葉劑，和剪除上半部，下半部及全部葉片處理TNG 4，TNG 15，KS 8與M34-1等四品系（種），探討落葉劑及剪葉處理對提早成熟期之效果與其對產量、品質之影響，並評估提早成熟期與產量之關係，以供栽培及育種參考，To evaluate the relation between accerating harvest and yield reduction of soybeans, 3 concentrations of paraquat and 3 defoliation treatments (including cutting of upper 50%, lower 50% and whole leaves) were applied at R6 (full seed) growth stage.
