本文研究了4个茶树品系春梢伸育过程中芽叶、叶位及节茎的粗纤维含量的变化规律。茶树春梢节茎的粗纤维变化曲线具有明显的粗纤维陡增现象,并且在品系中有较大的差异,提出了粗纤维含量陡增期的概念和以陡增期(陡增时期及陡增幅度)在品种之间的差异作为鉴定品种“持嫩性”的数量化指标,同时在4个品系中获得了节茎粗纤维含量与节茎长度之间的相关性分别为:y=3.364 2+11.43 87 x(r=0.986 1,极显著)、y=3.482 1+14.290 7 x(r=0.750 9,显著),y=21.696 9+9.880.5 x(r=0.952 2,极显著),y=31.964 6+7.529 3 x(r=0.859 3,显著),这些结果为茶树品种“持嫩性”的感官鉴定提供了理论依据。

The study is based on four tea strains. The results show thatthere is a sharp rise of RFC (rude fibre content) in the change curve of stem,and the sharp rise of RFC in the curve varies with strains. Therefore the dif-ference of sharp rise of REC in the curve of stem (including the time ofchange and the extent of change) between varieties can be used as the quantityparameters to determine the young-maintaining characteristic of shoots. The re-sults also show that the correlations between RFC and stem length in the fourstrains are respectively y=3.3642+11.4387 x (r=0.9861,most significant),y=3.4...
