摘  要：
以太子山林场管理局马尾松嫁接无性系种子园为研究对象,探讨雌雄球花在树冠中的分布及雌雄配子比例。结果表明:各无性系单株间马尾松雌雄球花数差异均达显著性水平,雄球花为291.61~1 549.69个/株,平均值为1 009.09个/株,变异幅度大;雌球花为135.40~636.39个/株,平均值为343.91个/株,变异幅度较大;雌雄球花比值变异幅度也较大(0.14~1.07)。不同无性系马尾松单株花粉产量间存在极显著性差异,平均单个马尾松花粉囊产花粉16 513.33粒,平均单株马尾松花粉产量为3.75×1011粒,全园花粉产量为2.03×1015粒。平均单个马尾松雌球花生产胚珠177个,平均单株马尾松产胚珠60 872.07个,全园产胚珠3.29亿个,种子园马尾松雌雄配子比例为1∶6.16×106;全年种子产量可期望达到约4 115.53 kg。

摘  要：
Distributions of both male cones and female cones in a tree crown and the ratio of female-male gamete were studied in Pinus massoniana clone seed orchard located in Taizishan,Hubei Province. The results showed that there were significant differences among the quantity of both male cones and female cones in the tree crown. The average number of male cones was 1 009. 09,ranging from 291. 61 to 1 549. 69 per tree whereas the average number of female cones was 343. 91,ranging from 135. 43 to 636. 39 per tree. The ratio of male cones to female cones was ranged from 0. 14 to 1. 07 for different clone mother trees. The average pollen number per sac, the average pollen per tree and all pollen in seed orchard was 16 513. 33,3. 75×1011and 2. 03×1015,respectively. There was a significant difference for pollen yield among different clone trees. The average ovule number per female cone,average ovule number per tree and all ovule in seed orchard was 177,60 872. 07 and 3. 29 billion, respectively. The ratio of pollen to ovule for the seed orchard of P. massoniana studied was about 1 to 6. 16×106. The seed yield in this seed orchard could theoretically reach to 4 115. 53 kg.
