摘要：

In order to characterize pollen viability and germinability by biochemical parameters, an introductory investigation was made of the germinability in vitro of pollen of 2 apple cultivars, 'Golden Delicious' and 'Starkrimson', partially self-incompatible and totally self-incompatible, respectively. Best results of percent germination were obtained for both cultivars after 120 min incubation in Petri dishes at 30°C in a medium containing 0.2 M sucrose, 20 μg/ml H3BO3, 300 μg/ml Ca(NO3)2 · 4H2O. Optimum pH was 6.0 for 'Starkrimson' and 7.0 for 'Golden Delicious'. © 1979.
