Pistil Development in Citrus Flowers

1. Ringing and defruiting of branches as well as ringing alone favored pistil development in flowers above the ring and hence increased the percentage of perfect flowers in Eureka lemon. 2. Ringing and defoliation together and defoliation alone resulted in poorer pistil development. 3. A positive correlation exists between the fluctuation in starch content of the shoots and the percentage of perfect flowers formed throughout the year.
