Karakteristik Dan Viabilitas Serbuk Sari 38 Ragam Tanaman Kamboja (Plumeria spp.) Di Bali

Abstract

This research aimed to know the characteristic and viability of 38 frangipani varieties’ pollen (Plumeria spp.) in Bali. The observation of pollen’s character used acetolysis method, whereas the observation of pollen’s viability used 1 % color of aniline blue. The measurement was done by micrometry. The result of the observation toward 38 frangipani varieties showed the variety of the length of polar axis between 36,48 ± 4,91 – 57,87 ± 3,89 µm, diameter of equatorial  between 30,18 ± 4,64 – 55,24 ± 5,52 µm, index P/E between 0,85 ± 0,10 – 1,42 ± 0,13, and also pollen’s viability in the amount of 21,51 %. The highest percentage of pollen’s viability was found in variety of P. alba L. 'Snow White' in the amount of 42,31 whereas the lowest was found in variety of P. rubra L. 'Red Ajanta'. Based on index P/E, the pollen of frangipani could be divided into group subpheroidal to prolat. Based on the length of polar axis, the pollen of frangipani could be divided into group media to magna.
