【摘要】 用AgNO3,ABT生根粉 2号、3号处理香木莲插穗的试验表明 :不同处理对香木莲生根率、根长、根径、生根条数等都有促进作用 .用综合指标评定得出最佳处理组合是ABT30 0 5g/kg,其次是ABT2 0 0 5g/kg .在塑料大棚中 ,平均温度 2 4℃ ,平均相对湿度 93 %的条件下 ,香木莲插穗生根率 1 0 0天时可达 89%.从生理上看处理后的插穗其光合速率、蒸腾速率均高于对照 .更多还原

【Abstract】 The authors have treated cutting branches of Manglietia aromatica by using silver nitrate, ABT rootage powder number 2 and number 3 then planting the treated branches in a greenhouse. The average temperature is 24 ℃ and the relative humidity is 93% in the greenhouse. The trial sample shows that the treatment cuttages have significant functions for rootage rate, root diameter,and the number of bourgeon root. After integrated analysis of the cuttages, the result is that ABT 3 of strength of 0.05 g/kg has the best treatment effect and then ABT 2 of strength of 0.05 g/kg has secondly treatment effect. When planting the treated branches for 100 days,the rootage rate of cuttages reaches to 89%. Both the photosynthesis rate of cuttages and the transpiration rate of cuttages are higher than contrast cuttages by physiological test.更多还原
