摘要：

Seedlings of green gram [Vigna radiata (L.) Wilczek] cultivar KM-2 were sprayed with different concentrations of triacontanol (TRIA) (0, 0.5, 1.0, and 2.0 mg dm(-3)) at 15 and 25 days after sowing. Foliar spray of 0.5 mg dm(-3) TRIA significantly promoted the plant height, fresh mass, and contents of chlorophylls, saccharides, starch, soluble proteins, amino acid and phenols. Leaf nitrate content was reduced by 0.5 and 1.0 mg dm(-3) TRIA with a corresponding increase in nitrate reductase activity. TRIA of 0.5 mg dm(-3) stimulated the onset of flowering, pod production and retention, but less number of pods and seeds per plant were observed at 2.0 mg dm(-3) treatment.
