油茶是一种异花授粉植物,实生繁殖的油茶实际是一种杂合体,遗传基础十分复杂。油茶实生林优劣两极分化突出,我站通过十三年观察,油茶实生林的优劣分化总趋势是劣向分化的多,优向分化的少。同一片试验林,在同样管理条件下,800多株油茶经八年分别单株测定产量,60%的植株,仅提供了30%的产量;个体平均产量低于总体平均单株产量一倍;而10%的良株及优株确提供了20%以上的产
Camellia oleifera is a cross-pollination plant, the actual propagation of Camellia is actually a hybrid, the genetic basis is very complex. The standpoint of the pros and cons of the actual plantation of Camellia oleifera stands out prominently. The total tendency of the pros and cons of the actual plantation of Camellia oleifera is inferior to the more differentiated and less well differentiated. Under the same management conditions, over 800 Camellia oleifera cultivars were tested individually for yield for eight years and 60% for the same test plant, which provided only 30% of the total yield. The individual average yield was less than twice the overall average single plant yield. And 10% of strains and excellent indeed did provide more than 20% of the production
