苹果树的树干上没有树枝,上面长满了短小幼嫩的果枝。这是在离不远的农业试验站十年研究的成果。新品种并不是通过改变遗传因子而获得。这种新奇的样本是六十年代在发现。是赤红色品种的加拿大亚种长时期进化的产物。这种变种的特点是在树杈上长出的不是平常的那种长枝,而仅仅是短小的嫩枝。实验站的科 No branches on the trunk of an apple tree, covered with short young fruiting branches. This is the result of a decade of research at an agricultural pilot station. New varieties are not obtained by changing genetic factors. This novelty sample was discovered in the sixties. It is the product of the long-term evolution of the Canadian subspecies of the crimson variety. The characteristic of this variant is that it is not the usual long branch grown on a tree branch, but only a short branch. Experimental Station Branch
