Abstract:
Pollen of six apple cultivars were used as materials,effects of medium components and storage conditions on pollen viability of them were studied.The results showed that ‘Mollie’ had the highest pollen viability in all six tested cultivars,followed by ‘Redchief’,with the lowest one for ‘Bramley’.The viability of pollen increased at the beginning and then declined with prolong of storage time,reaching its maximum value in 2 to 4 months.Dry and refrigerated storage were more favorable conditions to the pollen storage of tested apples.The most important ingredient of culture medium to the pollen germination was agar concentration and that to the pollen tube growth was boric acid concentration.The mediums with different ingredient combination were necessary to match with pollen germination or tube growth of the distinctive apple cultivars.
