桂林种质圃中猕猴桃分类群的观察和测试

本项工作始于1980年冬,几年来共收集了猕猴桃物种和变种32个,定植于种质圃者27个种。另收集了中华猕猴桃、美味猕猴桃、金花猕猴桃等经济价值较大的优良类型28个。猕猴桃各分类群果实的营养成分差异很大,维生素C含量高的可达1013.98mg/100g果实,低的仅为8.8mg/100g果实;不同种和变种的种子发芽率为1.5—51.62％;幼苗形态特征、物候期以及植株长势等均有明显差异。

OBSERVATION AND ANALYSIS OF ACTINIDIAS PLANTED IN GUILIN GERMPLASM ORCHARD

This subject was started in the winter of 1980. Thirty-two taxa of Actinidia have been collected, and twenty-seven taxa (including varieties) were planted in the germplasm plot. Twenty-eight good forms of some taxa from the field have also been selected and planted in the plot. The nutrient content in fruits of different taxa were considerable different, the highest content of vitamin C in fruits was 1013.98mg/ 100g. The germination rate of seeds of different taxa varied from 1.5% to 51.6%. There were considerable differences in morphological characteristics of seedling, phe-nophase and growth too.
