摘要:
为探索梨树生长势调控途径，选用矮生型和普通型2种类型梨树为试材，对树体生长发育，激素类物质代谢调控，以及利用嫁接技术对2种类型间的互作机制等进行了试验研究。结果表明：普通型与矮生型梨树在生长发育上存在差异，矮生型在整个生长季节只出现1个生长高峰；2种类型相互转接对抑制生长具一定的作用；在生长期间，使用6-苄基腺嘌呤（BPA）、赤霉素（GA3）涂抹处理普通型梨树，对新梢生长有明显的促进作用；此外，生长素转运抑制剂NPA处理能够显著降低普通型梨树的生长势，矮化调节作用明显。以上结果表明，梨树生长势受内部物质的调控，NPA对梨树生长势具一定的调节作用。
Abstract:
In order to explore the growth potential regulation pathway of pear tree，selecting the standard tree and dwarfed tree as the test materials.The difference in the growth，hormonal metabolism and interactions between standard tree and dwarfed tree were investigated.The results showed that there was difference in the growth between standard tree and dwarfed tree，the dwarfed tree only a growth peak in the whole growing season；the intergraft of two types had certain effect to the shoots growth；the period of growth，the standard and dwarfed tree treated by BPA and GA3 treatment promoted growth of shoots；in addition，the NPA treatment could significantly reduce the growth of standard tree and dwarfed tree.The results showed that the pear tree growth potential was regulated by the endogenous hormones，the NPA had a modified for pear tree growth potential.
