Morphological Observation on Flower Bud Differentiation and Influences of Storage Conditions on the Quantity of Flower Buds of Narcissus tazetta var.chinensis
摘要
Abstract
Paraffin cutting method was used to observe the developing process of the flower bud differentiation of Narcissus tazetta var. chinensis ' JinZhanYinTai' variety. The results showed that the flower bud differentiation process lasted about two months from bract primordia differentiation in early July to carpel primordia formation in mid-September. The process could be divided into 7 phases; leaf bud formation, inflorescence primordium differentiation phase, spathe primordia information phase, sepal differentiation phase, petal differentiation phase, stamen differentiation phase and pistil differentiation phase. The phase of petal differentiation was relatively long, a-bout 20 days. In terms of changes in the external growth of flower bud, it grew much faster in the late stage than in the early stage of differentiation. Data showed that the number of inflorescence increased after the July in virtue of smoke and sustained high temperature.关键词
