【摘要】 研究3个橡胶品系根、茎、叶水浸液对花生、西瓜、玉米3种受体作物种子及其幼苗生长的影响。结果表明,橡胶树根、茎、叶及其3种不同品系间(种内)的他感作用存在明显的差异。抑制作用强度为:叶>茎>根;热研7-33-97>海垦1>热研88-13。由此可见,胶园间作时,应当考虑橡胶树不同品系间他感作用的差异。更多还原

【Abstract】 The allelopathic effects of aqueous extract of root, stem and leaf from 3 strains of rubber trees (He-vea brasiliensis) on the seed germination and seedling growth of peanut, watermelon, maize were investigated.The results showed that the allelopathic effects of different organs and strains of rubber trees were significant-ly different, and the inhibiting intensity was in the following order: leaf>stem>root>; reyan 7- 33- 97>haiken1>reyan 88- 13. In conclusion, the different allelopathic effects of different strains should be taken into con-sideration during the intercropping period in rubber plantation.更多还原
