Different Floral Diversities of Garcinia indica Species and the Correlation of Their Functionality in Sexual Reproduction | Chapter 3 | Advanced Research in Biological Science Vol. 7

 Type Garcinia shows high variety of sexual systems as most class are dioecious in nature. Stated sexual plans of Garcinia include gynodioecious, androdioecious, monoecious and andromonoecious. Garcinia indica (Thouars) Choisy was reported as optional apomictic polygamodioecious species. G. indica exhibits abundant diversity in decorative types. As a result, orderly research of distinct floral types visualized on different types of G. indica plants was accomplished, with the aim of associating their functioning with intercourse reproduction. The study completed activity at Kokum Plot, BSSKVV, Dapoli. It revealed that the male plants maybe categorised into four floral types - androecious, functional men, andromonoecious and hermaphrodites. The flowers on female plants exhibited abundant variation in number and animation of stamens/staminodes. Each category granted significant difference in phenology, decorative morphology, and irritant types. In December, the percentage of staminate flowers (79.13±2.93%) in androecious timbers was significantly higher than working males (58.61±8.60%) or andromonoecious shrubs (56.36±2.77%) (p ≤ 0.01). As female plants started blooming, all male morphotypes bore significantly higher numbers of staminate flowers and carpellate flowers were considerably reduced. Irritant viability was maximum in androecious flowers at 90.11±1.10% and minimum at 64.70±2.09% in having male and female traits trees. Former studies reported that the female flowers bore well-developed female gametophyte, but shapely embryo incident was not observed. So, the fruit formation maybe apomictic. In present investigation; a round embryo was visualized in more than 60% of female and andromonoecious flowers between 8-24 hours afterwards anthesis but further enlightening stages like were not detected. G. indica shows usual Garcinia type of embryogenesis with the fetus appears as a long hypocotyl-radicle stalk with continuing on cotyledons.
