Flowering Behaviour in Different Species of Solanum
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 4
Abstract
In the present study, flowering behavior of various selected species of Solanum was traced. Comparison was made between the cultivated S. melongena varieties Haritha and Surya and the wild variants of Solanum viz., S. viarum, S. incanum, and S. gilo. The flowers of S. gilo and S. incanum opened between 5 a.m. and 6 a.m. as well as 6 a.m. and 7 a.m. respectively. Seasonal influence on the time of anthesis was prominent in the flowers of S. viarum. Here, the flowers opened between 11 a.m. and 11.30 a.m. during September – October period and between 6 a.m. and 7 a.m. during the rest of the year. In the wild variants S. viarum and S. incanum, anthers dehisced between 9 a.m. to 10 a.m. and 9 a.m. to 12 a.m. respectively depending on weather conditions. In S. gilo, the anthers dehisced nearly 30 minutes before flower opening. The change in the color of the stigmatic surface from glossy green to deep yellow at the time of initiation of stigmatic receptivity is a unique feature of S. gilo. In other wild variants of Solanum, the stigmatic surface at the time of peak stigmatic receptivity was observed to be moist plumpy and glossy green. Protandry is observed in S. gilo. While all other species were protogynous.
