摘要
用 HPLC 分析了茶树细根和新梢中的内源生长素(IAA)和脱落酸(ABA),结果表明,茶树细根中的 IAA 和 ABA 在休眠期均处于高峰,进入生长期后其含量明显下降,IAA/ABA 的比值愈小,细根的生长强度愈大,新梢伸育过程中,IAA 和 ABA 的含量以茶芽萌动期达到最高值,并随新梢伸育而降低。新梢生育受 IAA 和 ABA 含量水平的影响,更受 IAA/ABA 的比值所支配,比值大,生长强度也大。
The contents of IAA and ABA in rootlets and shoots of tea plant wereanalyzed with HPLC.The results indicated that during the dormant periodthe contents of IAA and ABA in rootlets was at high value but obviouslywent down when entering into the growth period.It was noted that thelower the ratio of IAA to ABA,the more active of the rootlets growth.The results also indicated that the contents of IAA and ABA in tea shootsreached to a top value during the shoot germinating period and decreasedwith the growth of shoots.The growth of tea shoots was related to thecontents,especially the ratio of IAA to ABA.In opposition to rootlets,the higher the ratio,the more active of the growth of tea shoots.
