OBSERVATION ON THE FLORAL ORGANOGENY OF PEANUT

In this paper, the process of floral organogeny of the peanut of 7 cultivars belonging in four cultivated forms (Spanish,Valencia Virginia and Hirsutum) has been observed. The results are as follows.1.Different types have different growing states for the lateral buds.2. Different types undergo diffrent developmental times for the floral organ-formative.3. All varieties coincide in the floral organogeny process. The whole process comprises 9 successive phase.the differentiation stage of the bud,of the calyx, of the stamen and carpel, of the corolla, of the ovule and semet, of the megasporocyte and microsporocytes,the meiosis of microspores and megaspores, the formation of embryo sac and maturation of pollen and the anthesis.
