The present study on phenology and reproductive biology of Nicotiana plumbaginifolia Vivane. was undertaken. It produces flower throughout the year and maximum flowering recorded in the month of February however minimum flowering was recorded in the month of April. The flowers are complete, actinomorphic with a long narrow floral tube of about 3-4.5 cm long and 1.5-2 cm wide. The flowers open at 7:00 am to 9:00 am in the morning while in evening the flower opens at about 5:30 pm to 6:00 pm.One flower produces an average 5,36,000 pollen grains. The higher pollen viability (85%) was recorded by Alexander’s stain while lower pollen viability (65%) was seen using 2,3,5-triphenyltetrazolioum chloride (TTC). The highest in vitro pollen germination in Brewbaker and Kwack’s medium is (53.45%) with longest pollen tube 415 um however lowest pollen germination (46.40%) is recorded in 15% sucrose solution. The flowers attracted the vide variety of insects for the pollination but bees and hawk moth were most significant pollinators. The fruit-set percentage is calculated as 45%.
