| 摘 要： | 目的]研究大蒜套种石榴控制石榴枯萎病的可能性。方法]在实验室条件下,采用不同浓度的0.2倍MS培养液和蒸馏水培养的大蒜根系分泌物,测定其对枯萎病菌和枯草芽孢杆菌生长的影响。结果]MS培养液和蒸馏水培养的大蒜根系分泌物均不能有效抑制枯萎病菌菌丝的生长。而同样2种方式培养的大蒜根系分泌物却对枯草芽孢杆菌的增殖具有较强的促进作用,且蒸馏水培养大蒜根系分泌物效果要优于MS培养液培养的根系分泌物。结论]石榴园套种大蒜结合枯草芽孢杆菌施用有望作为控制石榴枯萎病蔓延的一种方式。

| Abstract: | Objectives] This paper aims to explore the possibility to intercrop garlic with pomegranate tree to control pomegranate wilt.Methods] Root exudates of garlic is cultivated in 1/5 concentration of MS solution and distilled water is examined in lab to test their effect to growth of mycelia of pomegranate wilt pathogen(Ceratocystis fimbriata)and multiplication of Bacillus subtilis.Results] The result shows that garlic root exudates whatever cultivated in MS solution or distilled water could not inhibit or promote mycelia growth of C.fimbriata.However,garlic root exudates cultivated in both methods effectively promote multiplication of B.subtilis.Conclusions] It is suggested that intercropping garlic with pomegranate tree by combining application B.subtilis could be a promising way to prevent pomegranate wilt spread in practice. |
