摘要
叶斑现象常是园艺植物重要的性状,并能够大大提高植物的观赏价值和经济价值。加强中国的斑叶植物资源调查,收集和利用研究,不仅可以丰富遗传理论,保护斑叶植物遗传资源,还可以增加市场的花色品种。该文调查了龙门山地区野生和部分苗圃的斑叶植物,发现了18科24属29种34类未利用的斑叶观赏植物;而且植物的斑化现象与植物的科属特性有关,草本植物比木本植物多,单子叶植物比双子叶植物多。斑叶植物以耐荫植物居多。调查显示不同科属的植物有不同的叶斑表现,同一科属的植物也可以出现不同的叶斑类型。
Leaf variegation is an important trait for the horticulture plant. It can improve the economic and ornamental value. The investigation, collection and application of the variegated plants can not only enrich the genetic theory, protect the plant genetic resource, but also increase the plant variety on the market. This paper reports the investigation results： there are 18 families, 24 genera, 29 species, 34 types of variegated ornamental plants in Nongmen Mountain Area. The leaf variegation has some relationship with plant families and species. Liliaceae has more leaf variegations than others. Herbaceous plant has more variegation than woody plant. The leaf variegations in dicotyledon are more than that in Monocotyledon.
