Yield-related Analysis Based on Morphological Traits of Young Tea Plant

摘要: 为探讨茶树单株产量与形态学性状的相关性，本文对38个杂交一代单株（金萱×英红九号）的11个形态学性状进行实地调查。结果表明：修剪物重量、百芽重、发芽数和一级分枝数的变异系数都超过30%，有较大的变异选择空间；发芽数、叶面积、树高与单株产量存在显著的正相关，而百芽重则与单株产量存在显著的负相关。由于茶树各形态学性状间存在着复杂的相关关系，发芽数、叶面积、树高和百芽重对单株产量的决定系数仅为64.1%，在进行单株性状选择时，还需同时统筹考虑二级分枝数对各性状的正向间接效应，以及一级分枝数所带来的负向间接效应。Abstract: To investigate the relationship between the yield and morphological traits of a single tea plant, the field data collected from 38 first-hybrid-generation plants of Jinxuan（Camellia sinensis） and Cuiyu（Camellia sinensis）involved with 11 morphological traits showed that pruning weight, one-hundred-bud weight, the numbers of germinative buds and primary branches had a greater variation in choice, and the coefficient of variation（CV）of which were more than 30%. The morphological traits, such as germinative number, leaf area and plant height, had significant positive correlations with the individual plant yield, but a significant negative correlation would be revealed for one-hundred-bud weight. Because of complex relationship among different morphological traits, the decision coefficient of germinative number, leaf area, plant height and one-hundred-bud weight to the individual plant yield was only 64.1%. Therefore, the indirectly positive effects from the secondary branches as well as negative effects from the primary branches to the other morphological traits should be coordinately considered during the plant trait selection.
