根据2个产地154个无性系种子园种子播种品质测定、研究、分析认为：①各产地单桂平均种子产量的多少主要是由单果平均重和球果数量等因子决定的；②各无性系间种子产量和播种品质差异极大，这些差异为结实优良无性系的再选择提供了理论依据；③两产地均有50％以上的无性系千粒重有随树龄的增长而呈上升的趋势；④经相关分析，发芽率与发芽势、单果重两因子均达显著水平，而与千粒重、出税率等因子则相关性较差；⑤在评定无性系优劣时，除考虑生长量、结实量而外，发芽率等播种品质也是一个不容忽略的主要因子。
According to the measurement and research on the seed sowing quality of 154 clonal seed orchards in 2 producing areas, the results showed that: (1) the average seed yield per unit area was mainly determined by the average weight of individual fruit and the number of cones; (2) Seed yield and sowing quality are very different, these differences provide a theoretical basis for the re-selection of the sturdy and excellent clones; (3) the 1000-grain weight of clones with more than 50% of the two producing areas has a tendency to rise with the increase of the age; (4) The results showed that the correlation between germination rate and germination potential and single fruit weight reached significant level, but the correlation coefficient was not significant with 1000-grain weight, tax rate and other factors; ⑤In evaluating clonal quality and abundance, Germination rate and other planting quality is also a major factor can not be ignored.
