| 摘 要： | 樟子松种子园无性系间的花粉量、种子产量均存在着差异,这种差异,是由樟子松无性系本身的遗传基因决定的.种子园中,往往少数无性系控制着园内50%以上的花粉量和种子产量.由于部分无性系种子产量低,育苗、造林时这些家系则容易丢失.为减少家系的丢失数量,育苗时,应改善圃地的环境条件,增加土壤肥力,加强除草等抚育措施,提高育苗水平.

| Abstract: | There were differences in amount of pollen and seed among clones of Pinus syloestris vat. Mongolica, which was controlled by genetic genes. It happened that over 50 percent of the amount of pollen and seed was dominated by minority clones in the orchard. Some clones produced too little seeds to be kept in nursery or plantation. In order not to lose clones measures should be taken to improve soil fertility, tending, nursery condition and cultivation. |
