将MM_(106)和M_9砧上的首红元帅苹果植株采取不修剪、冬剪(定植当年),和夏剪(定植后12周)等处理以研究修剪和砧木对植株第一个生长季节期间的根系和枝梢间的干重分布的影响。在定植后最初6周期间,冬剪促进了新梢干重增加,降低了新根干重。然而,到12周时新根干重和新梢干重间则几乎无差异。夏剪导致了新梢生长的显著
The first red marsh apple plants on MM_ (106) and M_9 anvil were treated with no pruning, winter pruning (the year of planting) and summer pruning (12 weeks after planting) to study the effect of pruning and rootstocks on the growth of plants during the first growing season The effects of dry weight distribution between roots and shoots. During the first 6 weeks after colonization, winter shears promoted the increase of shoot dry weight and decreased the dry weight of new roots. However, there was almost no difference between the new root dry weight and the shoot dry weight by 12 weeks. Summer cut led to the growth of new shoots significantly
