INTRODUCTION
In recent years, insufficient pollination has been found to be one of the important limiting factors for low yield in many field and orchard species (Shivanna & Sawhney 1997). Some species require management of pollinating agents, while others need artificial means of pollination, one of which is pollen supplementation (Hopping and Jerram 1980a 1980b), involving three major steps: (1) pollen collection; (2) pollen storage; (3) pollen deposition on receptive stigmas.
