葉綠素含量的變化在果樹中的體現

葉ye綠lv素su含han量liang的de多duo少shao，是shi果guo樹shu光guang合he作zuo用yong效xiao率lv的de衡heng量liang依yi據ju。因yin為wei葉ye綠lv素su是shi光guang合he作zuo用yong的de主zhu要yao場chang所suo，葉ye綠lv素su含han量liang多duo，直zhi接jie表biao明ming果guo樹shu的de光guang合he作zuo用yong強qiang
，同tong時shi也ye預yu示shi著zhe果guo樹shu的de產chan量liang高gao。但dan是shi果guo樹shu在zai不bu同tong時shi期qi
，其qi葉ye綠lv素su含han量liang是shi不bu同tong的de
，不bu同tong果guo樹shu，其qi葉ye綠lv素su含han量liang也ye是shi不bu同tong的de。葉ye綠lv素su含han量liang可ke代dai表biao葉ye片pian光guang合he效xiao能neng，反fan映ying植zhi株zhu營ying養yang水shui平ping。因yin而er對dui於yu葉ye綠lv素su含han量liang的de測ce量liang以yi及ji研yan究jiu有you一yi定ding的de意yi義yi，通tong過guo對dui果guo樹shu的de生sheng長chang過guo程cheng中zhong的de葉ye綠lv素su含han量liang的de測ce量liang以yi及ji了le解jie對dui於yu果guo樹shu的de光guang合he速su率lv以yi及ji養yang分fen的de累lei積ji有you一yi定ding的de幫bang助zhu，果guo樹shu生sheng長chang過guo程cheng中zhong的de葉ye綠lv素su含han量liang的de測ce量liang可ke以yi使shi用yong葉ye綠lv素su測ce量liang儀yi來lai進jin行xing側ce量liang，同tong時shi也ye可ke以yi使shi用yong浸jin提ti法fa以yi及ji分fen光guang光guang度du計ji來lai進jin行xing測ce量liang，本ben文wen就jiu是shi通tong過guo對dui葡pu萄tao生sheng長chang過guo程cheng中zhong的de葉ye片pian葉ye綠lv素su含han量liang來lai進jin行xing了le解jie，以yi此ci判pan斷duan葡pu萄tao的de生sheng長chang過guo程cheng。

，它(ta)的(de)主(zhu)要(yao)變(bian)化(hua)規(gui)律(lv)是(shi)：(1)快速增長期：在葡萄開始展葉時，葉片葉綠素含量極低，僅為0.0131 mg/cm2，隨著葡萄的生長
，葉綠素含量在慢慢的增加
，直到葡萄展葉後30d葉綠素含量就開始急速上升
，且增長量較為均勻，日增0. 0011 mg/cmz。(2)緩慢增長期：suizheputaoyepiandejixushengchang，qizhongdeyelvsuhanliangzengchangdesudujianghuimanmandejiangdi，zhanyehoudaoyidingdetianshuzhihou，yelvsuhanliangdezengchangsudujianghuibianman，tongguoceliangyijibijiaofaxianyelvsuhanliangderizengzuiduowei0.00013mg/cm2。
