POLLEN STUDIES IN KIWIFRUIT (ACTINIDIA DELICIOSA CHIVE.)
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
In the present study difference in the shape and size of the pollen grains was observed under different condition. Maximum length of pollen (186.5µ and 119.47µ in both male and hermaphrodite plants respectively) was recorded under dry condition and the pollen were look like bar shaped structure. When the pollen grains are hydrated, they took the spherical shape. Male flower pollen grains contain trinucleate pollens where as hermaphrodite pollen grains contain shriveled inner cell content. The pollen of both male and hermaphrodite flower shows 100 % viability on the day of anthesis under natural condition. The pollen grains remain viable for 3 days but in pistillate flowers there is a rapid decrease in the viability compared to male pollen grains under natural condition. The maximum pollen germination (91.60%in male flower and 25.20% in hermaphrodite flower) and longest pollen tube (2483.10µ and 550.02µ in male and hermaphrodite flower respectively) was recorded with the combination of 0.5% boric acid and 15% sucrose solution.
