利用随机区组试验评估了孟加拉国吉大港大学苗圃内的银合欢落叶对森林作物种白格、黄金檀和农田作物种长豇豆、鹰嘴豆和木豆的他感作用。结果表明,凋落叶诱导抑制作物的萌发和生长,该抑制作用依赖于萃取物浓度、凋落物及受体物种类型。萃取物浓度越高则他感作用越强。受体植物的生长响应随应用的凋落叶而变化。低浓度(10g·m-2)凋落叶对农田作物嫩芽生长有促进作用,而其他浓度的凋落叶则呈现明显的抑制作用,施用的凋落叶浓度越大抑制作用也越大。但是不同处理所表现出的抑制趋势并不均一,根系生长受到的影响大于嫩芽。图3表4参34。
A randomized block trial was conducted to assess the effects of silver deciduous leaves in nurseries at the Chittagong University Nursery in Kuala Lumpur on species of white forest, golden sand and farm crops of asparagus bean, chickpea and pigeon pea. The results showed that litter leaf induction inhibited the germination and growth of the crop, the inhibition depends on the concentration of extract, litter and receptor species types. The higher the extract concentration, the stronger his sense of role. The growth response of recipient plants varied with the litter used. Litter leaves with low concentration (10g · m-2) could promote shoot growth in farmland, while litter leaves at other concentrations showed obvious inhibition effect. Larger concentration of litter leaves inhibited the growth of shoots. However, the inhibition tendency exhibited by different treatments was not uniform, and the root growth was more affected than the tender shoots. Figure 3 Table 4 Reference 34.
