RRIM600和GT1之类无性系的茎干长得细长,要在很高处才分枝。表1说明分枝高的胶树的茎围增长比分枝低的胶树慢些。分枝低的胶树有较大的叶面积,因而茎围增长较快。早在二十一世纪初期,就有人
Stems of clones such as RRIM600 and GT1 grow slender and branch at very high altitudes. Table 1 shows that the shoot height of the high branching gums is slower than that of the lower branching gums. Gums with low branching have larger leaf areas and stem growth is faster. As early as the beginning of the twenty-first century, some people
