Influence of Temperature on Pollen Tube Growth and Initial Fruit Development in ‘d’Anjou’ Pear1

Abstract

Pollen tube growth in styles of ‘d’Anjou’ pear ( Pyrus communis L.) is largely dependent on prevailing temp. At 21°C the process was completed within 24 hr, while at 15.5° and 10° growth was completed by 72 and 120 hr respectively. The initial fruit development 14 days following pollination was greatly influenced by day temp (ranging from 13° to 23.4°) during an thesis.
