Viability and Storage of Lily Pollen

The study was conducted to estimate the pollen viability of eight lily genotypes and to identify their optimum storage conditions. Pollen viability was assessed by in vitro germination, FCR (fluorochromatic reaction) test, and in vivo assays. Pollen grains were stored in the dark chamber where the room temperature was maintained at 4, -20, or –70 oC for 1 year. The highest percentage of pollen germination in L. henryi, L. lancifolium, L. Oriental ‘Casa Blanca’ , L. formolongi ‘F1 August’ and ‘Raizan’ was observed when pollen grains were stored at temperatures lower than –20 oC from FCR test and in vitro study. On the other hand, the lowest percentage was found in pollen of ‘Connecticut King’ , ‘Barbaresco’ , and ‘Kissproof’. These cultivars have shown poor germination rate of 10% or lower under four storage conditions. The best storage condition seemed to be low temperature of –20 oC or lower. Pollen grains of ‘Raizan’ , ‘Casa Blanca’ , ‘Casa Blanca’, and L. lancifolium, after 1 year storage (except for room temperature) still had sufficient capacity for fruit set after crosspollinations. Highly significant correlations were found among the FCR test, in vitro germination, and fruit set test.
