- This aims of the research was to determine the structure and pollen viability of RangdaCoconut (Cocos nucifera L. “Rangda”) stored at different time and temperatures. Pollen sampleswere collected from Gianyar, Klungkung and Negara. The experiment was conducted at theLaboratorium of Forensic and the Laboratorium of Plant Development and Structure, UdayanaUniversity, from October 2012 to January 2013. Pollen structure was analyzed with acetolysemethod, while pollen viability was analyzed in-vitro. The results showed that the structure of thepollen of “Rangda” coconut was circular, media, monosulcate, Subferoidal-Prolat, Sferoidal.Pollen viability of “Rangda" coconut was low (less than 3%). Pollen stored in the freezer has thebest viability, which continually increased until the 2nd weeks, then declined after that, whiepollen viability stored at room temperature tend to decline up to the fourth weeks.Keywords: structure, viability, pollen, time, storage
