| Summary: | This aims of the research was to determine the structure and pollen viability of Rangda<br />Coconut (Cocos nucifera L. “Rangda”) stored at different time and temperatures. Pollen samples<br />were collected from Gianyar, Klungkung and Negara. The experiment was conducted at the<br />Laboratorium of Forensic and the Laboratorium of Plant Development and Structure, Udayana<br />University, from October 2012 to January 2013. Pollen structure was analyzed with acetolyse<br />method, while pollen viability was analyzed in-vitro. The results showed that the structure of the<br />pollen of “Rangda” coconut was circular, media, monosulcate, Subferoidal-Prolat, Sferoidal.<br />Pollen viability of “Rangda" coconut was low (less than 3%). Pollen stored in the freezer has the<br />best viability, which continually increased until the 2nd weeks, then declined after that, whie<br />pollen viability stored at room temperature tend to decline up to the fourth weeks.<br />Keywords: structure, viability, pollen, time, storage
