孙胜华同志: 您提出在单色品种的山茶花中有时会开出复色花朵,正如您所说,这是山茶花发生自然变异的现象,又称芽变。变异是一切生命物质的属性,是生物界广泛存在的普遍现象。生物的变异是多种多样的,概括起来可分为遗传的变异和不遗传的变异,遗传的变异是指变异发生后能够遗传给后代,观赏植物中的许多变种,变型,均属这类变异,如绿色黄杨变为金心黄杨,单瓣牡丹变成重瓣牡丹。无香味的仙客来变为有香味的仙客来等。又如您提到的山茶“赤丹”鲜红的花瓣中 Comrade Sun Shenghua: You proposed that the monochromatic flowers of the camellia in monochromatic varieties sometimes open up. As you said, this is a phenomenon of natural variation of the camellia, also known as bud transformation. Variation is the property of all living things and is a widespread phenomenon in the biological world. Biological variation is diverse, can be broadly divided into genetic variation and non-genetic variation, genetic variation refers to the mutation can be passed on to future generations, ornamental plants in many varieties, variants, are such variations , Such as green boxwood into the heart of the boxwood, single peony into double peony. Unscented cyclamen into a scented cyclamen and so on. In another example, you mentioned camellia “reddish” red petals
