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).

Key words: tea shoot, chlorophylls, biosynthesis, precursors, shading, low illumination intensity
