摘要
脱落酸(ABA)处理可以显著地提高寒光苹果果实的着色程度,同时使果实的一些重要品质提高。ABA处理促进了果皮花青苷合成和叶绿素降解,提高了果皮苯丙氨酸解氨酶(PAL)的活性。研究表明,ABA处理改变了果实成熟过程中内源激素含量之间的动态变化和平衡,即ABA处理降低了果实中赤霉素(GA3)的含量,改变了果实中生长素(IAA)与玉米素(ZR)之间的动态含量平衡。
ABA treatment promoted highly color formation of skin and enhanced some important qualities tor Hanguang apple. ABA treatment was favorable for accumulation of anthocyanin content and reduction of chlorophyll content,and aslo improved PAL activity. The study showed that ABA treatment played a role on altering content and balance among hormones during maturation of the fruits. ABA treatment increased ABA content while decreased GA3 content in the fruits. In addition, ABA treatment altered the balance between IAA and ZR content in the fruits.
