| 摘 要： | 以山东淄博原山林场1986年定植的23 a生侧柏林分为研究对象,对来自全国37个种源的侧柏进行生长及开花特性研究。结果表明:胸径和每平方厘米胸高断面积的雄花数遗传力分别为0.816和0.823,遗传性状稳定。种源间生长指标存在明显差别,河北获鹿、河南禹县、山东平阴等种源的胸径分别为10.54、10.221、0.14 cm。不同种源开花指标差异显著,雄花的开花量普遍较大,雄花比例超过90%的有29个种源,甘肃徽县、山东益都等17个种源均超过96%,为富雄花种源。雌花的花量少,雌花比例高于20%的仅有北京密云1个种源,且种源间差别较大。

| Abstract: | Taking 23-year old stand planted in Yuanshan forest farm in 1986 as research object,the growth and the flowering characters of Platycladus orientalis of 37 provenances were analyzed.The results showed that the heritability of diameter at breast height(DBH) and number of male flowers per square centimeter were 0.816 and 0.823,respectively.Genetic characters were stable.Indices of growth among provenances were remarkably different,the DBH were 10.54 cm,10.22 cm,and 10.14 cm,respectively for those from the pro... |
