| 摘 要： | 研究了遮阳网遮荫处理对鸠坑、龙井43、水古新梢叶绿素生物合成前体物质和新梢叶绿素积累的影响。结果显示：遮荫降低光照强度,茶树新梢叶绿素含量显著增加;同时叶绿素生物合成的前体物质δ-氨基酮戊酸（aminolevulinic acid, ALA）、卟啉胆色素原（porphobilinogen, PBG）、尿卟啉原Ⅲ（Urogen Ⅲ）等含量降低,而原卟啉Ⅸ（protoporphyrin Ⅸ, ProtoⅨ）、镁原卟啉Ⅸ（magnesium protoporphyrin Ⅸ, Mg-ProtoⅨ）、原叶绿素酸酯（protochlorophyllide, Pchlide）含量升高。

| Abstract: | Effects of light-shading on accumulation of chlorophylls and their biosynthetic precursors in tea cultivars Jiukeng,Longjing43,Shuigu were investigated using dark light-shading net.It showed that light-shading increased the accumulation of chlorophylls in tea shoots,accompanying decrease in levels of aminolevulinic acid(ALA),Porphobilinogen(PBG) and urogen Ⅲ and increase in levels of protoporphyrin Ⅸ(Proto Ⅸ),magnesium protoporphyrin Ⅸ(Mg-Proto Ⅸ) and protochlorophyllide(Pchlide). |

| Keywords: | tea shoot chlorophylls biosynthesis precursors shading low illumination intensity |
