摘要:
Pollen, from pellets gathered by bees, was used to pollinate kiwifruit flowers artificially. Pollen was applied at a number of rates after suspending in an aqueous medium or mixing with one of three different diluents to get a powder formulation. Resulting fruit size was less at lower rates of pollen application. At such low rates (generally < 1.0 mg/flower), a linear relationship was detected between pollen application rate and final fruit size, in some seasons. Some powder formulations (e.g., that usingLycopodiumspores) seemed less effective than the aqueous suspension. However, the best formulation for pollination of kiwifruit was made with an inert powder. This formulation effectively set fruit at rates of pollen as low as 0.037 mg/flower, although at this rate fruit size was reduced as a result of inadequate seed set.
