柘树属一新变种—金脉柘树

A new species of Cudrania tricuspidata(Carr.) Bur.var.auratovariegata

在泰山发现自然生长的全株叶片沿叶脉银白或金黄色的柘树,经嫁接和组织培养的子代植株或再生芽均保持原有形态特性,其为柘树属一新品种(变种)。

All of leaves of Cudrania tricuspidata （Cart.） Bur. var. auratovariegata, which is growing in natural condition, is found in Tai mountain that it has slivery white or yellow nervures. However, both of its filial plants and regenerated buds by grafted or tissue culture possess of intrinsic morphological characters. So we think that it is a new breed （variety） of Cudrania.
