Observation on Flower Bud Differentiation of Crape Myrtle in Red Soil Environment

Flower bud differentiation is a key component of plant blooming biology and understanding how it works vital for flowering regulation genetic breeding, increasing the number quality flowering. Red soil most widely covered type in world, also suitable crape myrtle planting. The flower buds (Lagerstroemia indica) planted red were employed as experimental materials this study, distinct periods identified using stereomicroscopy paraffin sectioning. We optimized steps dehydration, transparency, embedding, sectioning staining when employing sections. When seen under microscope, optimization can make cell structure sections obvious, tissue complete, clear natural. process divided into 7 based on anatomical observations external morphology internal during differentiation: undifferentiated period, start inflorescence calyx petal stamen pistil period. time concentrated from end May to mid-June. Crape complicated process, specific regulatory mechanism affecting elements need be investigated further.
