对异花玉兰的冬芽种类、拟花蕾、分枝习性及成枝规律等因子进行了观测,并对冬芽和拟花蕾进行解剖,结果表明:①当年生枝上有休眠芽、叶芽和拟花蕾3种;②叶芽与拟花蕾外均包被着3~4层芽鳞状托叶,最外层薄革质,外面密被短柔毛,内层纸质-膜质,外面疏被长柔毛;③分枝习性基本为预生分枝呈单阶无歧生长规律.
對異花玉蘭的鼕芽種類、擬花蕾、分枝習性及成枝規律等因子進行瞭觀測,併對鼕芽和擬花蕾進行解剖,結果錶明:①噹年生枝上有休眠芽、葉芽和擬花蕾3種;②葉芽與擬花蕾外均包被著3~4層芽鱗狀託葉,最外層薄革質,外麵密被短柔毛,內層紙質-膜質,外麵疏被長柔毛;③分枝習性基本為預生分枝呈單階無歧生長規律.

Some results of the Yulania varians T.B.Zhao,Z.X.Chen et Z.F.Ren are studies in this paper,which do some observation of the characteristics of buds,similiar flower buds,branches of buds and anatomy in winter. The results as followings:1) there are three types of buds on the spring branches of present year, such as latent buds,leaf buds and similar flower buds;2) the stipule like bud scales can be found in similar flower buds and leaf buds and they are three to four layers. The most outside layer is thin,coriaceous and densely covered by short fluff, and the others are paper or membranous texture and sparsely covered by white,long fluff.3)the ramification belongs to prolepsis,behaving the regularing of single step without branch.
