不同家系海南大叶种茶苗期生长差异分析OA

In order to understand the growth differences of Camellia sinensis var.assamica from different families at seedling stage in Shuiman Township of Wuzhishan City,and provide a certain basis for subsequent germplasm resource screening,this paper measured the seed germination rate,germination time,plant morphology,leaf morphology,biomass of tea seedling,and conducted a variance analysis on various growth indicators.The results showed that the coefficient of variation of growth indicators of Camellia sinensis var.assamica from different families varied,ranging from 4.58% to 37.27%,with abundant variation and great potential for breeding.The germplasm resource with the highest germination rate was ZZ1-3(89.06% ),and the germplasm resource FX2 had strong growth,with a plant height of 10.40 cm,a ground diameter of 1.94 mm,an average number of 3.20 leaves,a leaf length of 7.09 cm,a leaf width of 3.68 cm and an aspect ratio of 1.93.
