花药体细胞植株,集芽接树和实生树的优点于一体,是一种幼态自根无性系,表现出许多优良性状: 1.生长快。比母体芽接树快9—20％,大致可提早一年开割投产。 2.产量高。海垦1和海垦2花药体细胞植株头两割年平均单株产量分别为母体无性系的131％和143％。 3.发育阶段从老态回复到幼态。表现在:和实生苗一样有一条粗壮的主根及一轮侧根;茎干圆锥度大,酷似实生树;取1.5年生植株的芽片芽接,抽生的嫩枝与砧木夹角小。这和老态型(抽生嫩枝与砧木夹角大)有明显差别,植株性状整齐一致;抗逆性强,经济寿命长,可排除砧木对接穗的不良影响。因此花药体细胞植株是一种很有发展前途的新一代种植材料。
Anther somatic cell plant, set the budding tree and the advantages of the real tree in one, is a juvenile root system, showing many excellent traits: 1. Fast growth. 9-20% faster than the parent budding tree, which can be put into operation roughly one year ahead of schedule. 2. High output. The average yield per plant of the first two year cuttings of Nongken 1 and Nankin 2 anther somatic plants were 131% and 143% of that of maternal clones respectively. 3. Developmental stage from the old state to the juvenile state. The performance is as same as the seedling, there is a stout main root and a lateral root. The stem has a great conicity and resembles a real tree. Take shoot bud sprouts of 1.5 years old plants, and the angle between the young shoots and rootstocks is small. This and the old state (shoots shoots and the angle between the rootstocks) have significant differences, plant traits neat; strong resistance, long economic life, you can rule out the adverse effects of rootstock scion. Therefore, anther somatic cell plant is a promising new generation of planting materials.
