植物繁衍后代一般有两种途径,即有性生殖和无性生殖。前者是通过雌性和雄性生殖细胞的结合产生种子,由于森林树种多数是异花授粉植物,其遗传组织成分是不同的。用种子繁殖的后代,个体间有很大的差异,容易产生变异,不能保持种的真实性或类型;后者是利用植物部分割裂的营养体(根、茎、叶)繁殖,形成独立的植物。凡是 There are two general ways in which plants multiply offspring: sexual and asexual reproduction. The former produces seeds through the combination of female and male germ cells. Since the majority of forest tree species are allotroot pollinated plants, their genetic tissue composition is different. Progeny that breed with seeds vary greatly among individuals and are prone to mutation that can not maintain the authenticity or type of the species; the latter is propagated using vegetative bodies (roots, stems, leaves) that are partially fragmented by plants and form independent plants . all
