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