1989年在佐治亚大学生态所温室用缺速效磷的灭菌河沙土,在328个无菌盆栽中研究了棉花等7种作物接种G.etunicutum等5种VAM真菌孢子混合液后的生长反应情况,每立方厘米无菌土中接入3个混合孢子为+VAM处理, 对照不接,对比法排列,生长期70多d.结果表明,+VAM处理的棉花、玉米、大豆、西红柿的苗干重分别比各自的对照高947%.74.2%,27.8%和124.9%,而西瓜和油菜则无显著反应(t检验);G.macrvcarpum菌种可能有较强的孢子生产能力.
In 1989, the growth responses of five VAM fungal spores mixed with G. etunicutum to seven kinds of crops such as cotton were studied in 328 sterile potted plants using the short-acting phosphate-sterilized river sand in the Greenhouse of the University of Georgia. Three mixed spores per cubic centimeter of sterile soil access + VAM treatment, the control is not connected, the contrast method, the growth period of more than 70 d.The results showed that, + VAM treated cotton, corn, soybean, tomato seedling weight Respectively, were 947%, 74.2%, 27.8% and 124.9% higher than their respective controls, while watermelon and canola showed no significant response (t-test). G.macrvcarpum strains may have strong sporulation capacity.
