橡胶树不同长势砧木对不同栽培品种(接穗)生长等的影响

Effect of Rootstocks with Different Growing Situations to Growth of Various Rubber Tree Varieties(Scion)

通过在大、小砧木上同时芽接两个不同橡胶树品种,研究不同长势砧木对接穗生长的影响,以及同一接穗品种生长在不同的处理组合间的差异,结果表明:砧木对接穗生长高度因砧木大小、处理接穗品种组合不同而不同,大砧木上两两组合接穗的生长高度均比小砧木上的生长高度要高;同一时期大砧木上接穗茎粗要比小砧木上接穗茎粗粗,且增长要快,不同长势砧木对接穗茎粗增长的影响因接穗品种不同而不同,同一品种接穗茎粗增长也因处理组合不同而有差异;不同长势砧木对接穗叶蓬生长及平均叶蓬距的影响因品种而异,同一品种叶蓬生长及平均叶蓬距因芽接处理组合的不同而不同。

Through grafting the buds of two different rubber tree varieties to large or small rootstocks at the same time,the effect of rootstocks with different growing situations to the growth of the scion as well as the differences in the growth of the same scion among different treatment combinations were studied.The results showed that the growth height of the scion depended on the size of the rootstock and the combination of scion variety,and the growth height of the scion on the large rootstock was higher than ...
