The present study was conducted on ten mango cultivars namely Alphonso, Bangalora, Kalepad, Himayuddin, Sendura, Mulgoa, Neelum, Rumani, Banganapalli and Swarnarekha and seasons are main and off-season at Kanyakumari and Tenkasi.  The stem along with bud sample was collected during the month of October and November and conducted to examine the relation between internal structure of leafy and reproductive bud. During main season. Among ten mango cultivars, Bangalora and Swarnarekha have well developed at kanyakumar during main season for stage I, whereas Tenkasi, Alphonso and Bangalora well developed buds during the main season in stage I was observed. During off-season observed at kanyakumari Neelum and Alphonso had well developed for vegetative bud in stage I. At Tenkasi cultivars Kalapad and Bangalora had well developed for vegetative bud in stage I. The climatic factors prevailing at Kanyakumari during the main and off seasons for the months of August to September low temperature (19⁰C to 21⁰C) and high humidity (85 to 90%) and main season for the month of October to November, low temperature (21⁰C to 23⁰C) and humidity (80 to 85%). Whereas reproductive stage observed mango cultivars, Alphonso, Bangalora, Kalapad, Neelum and Swarnarekha had well developed reproductive buds in stage II & III during main season at kanyakumari. During off-season, cultivars of Himampasand, Kalapad, Alphoso, Neelum and Swarnarekha had well developed reproductive bud for stag II & III was favoured different stages of bud differentiation in the ten cultivars of mango.
