种子园的花粉管理是种子园经营管理的最重要的基础工作。该管理工作包括促进花芽分化到促进授粉结实等一系列措施。管好种子园的花粉,可使交配按最有效的方式进行,使子代群体获得最大的遗传增益。一、种子园基本情况研究选用1979年嫁接的马尾松初级种子园,面积为5.3公顷,共收集56个优树无性系,株行距4×4米,园内单株平均高5.2米,平均冠幅3.7 x 3.7米,平均胸径9.2厘米。1984
The pollen management of the seed orchard is the most important basic work of seed garden management. The management includes promoting flower bud differentiation to promote pollination and a series of other measures. Control the pollen in the seed orchard can make the mating work in the most efficient way and maximize the genetic gain for the progeny population. First, the basic situation of the seed orchard Selected grafted Masson pine primary seed orchard in 1979, an area of 5.3 hectares, collected a total of 56 superior tree clones, spacing of 4 × 4 meters, the average height of 5.2 meters in the park, the average crown 3.7 x 3.7 m, average diameter of 9.2 cm. 1984
