Summary
Pollen of theSolanum phureja clone IVP48 was stored with silica gel desiccant at −15°C for periods ranging from one month to five years. When used to pollinate anotherS. phureja clone there was a significant negative correlation of pollen age with the number of seeds produced per berry. The frequency of berry production and number of seeds per pollination, however, did not show significant negative correlations and berry production varied unpredictably with pollen of different ages.
Each year of pollen storage reduced the average number of seeds produced per berry to about 60 per cent of the preceding year's.
