Cross - Artificial Pollination on Hibiscus Rosa-Sinensis L.

The study was focused on pollination of Hibiscus rosa-sinensis L. The study area is situated at Therkkumedu, Salem district. The study initiated from May 2016 to February 2017. Flowering initiation, fruit set, fruit intiation and maturation of fruits, seed production and germination was observed from september 2016 to February 2017. Natural pollination of Hibiscus rosa-sinensis L. resulted 0 % fruit set, because there are no any pollinators or insect visitors. In controlled pollination treatments one type of pollination were examined. That is cross pollination, resulted better results and moreover it confirms the pollination take place by hand pollination. This method is give 100 % result Hibiscus rosa-sinensis L. Naturally the pollination and fruit set is very rare in Hibiscus rosa-sinensis L. Artificial cross-pollination was followed in two different character of Hibiscus rosa-sinensis L. mother plants. Both are Red colour with contrast flower character. The result positive in one type of mother plant, result negative in another type of mother plant. Because the flower character is entirely different.
