SH1和Y-1中间砧对长富苹果营养生长的比较研究
The comparative study of vegetative growth of 'Nagafu 2' apple on SH1 and Y-1 dwarfing interstocks
摘要
Abstract
[Objective]This experiment was to comparatively study the vegetative growth of ''Nagafu 2'' apple on SH1 and Y-1 dwarfing interstocks,and which could offer theoretical basis for selecting and employing dwarfing interstocks in different places.[Methods]The ''Nagafu 2'' apple on SH1 and Y-1 dwarf interstocks were used to investigate the growth potential of branches and leaves and analyze.[Results]The growth of shoots of Y-1 dwarf apple trees was significantly shorter than SH1 trees.And its short branch rates (64.43%) was higher than that of SH1 interstock(44.45%),but the protortion of long branch(10.50%) was lower than SH1 interstock apple trees(19.21%).The internode length was also shorter than SH1 interstock trees,shorter 80.51%.Leaf thickness,SLW(specific leaf weight) and carotenoid content were higher than SH1,but had no significant difference.[Conclusion]Y-1 dwarf interstocks was more beneficial to lower the growth potential of ''Nagafu 2'' apple,and increased its leaf thickness and SLW,which could improve the nutrient accumulation.Moreover,it also could increase carotenoid content,which could improve ability of photoprotection.关键词
