Improvement of pear production (M. Quinet)

Parthenocarpy induction by spraying plant hormones is a common practice in pear tree ‘Conférence’ orchards. However, flower pollination and fertilization increased ‘Conférence’ fruit size but pear flowers are not attractive to insects. In order to improve pear production, our project aims to better highlight the pear tree reproduction and focuses on the pollination and parthenocarpy processes in the’ Conférence’ cultivar.
