Research Project: IMPROVING FLOWERING OF LONGAN AND LYCHEE TREES IN HAWAII Project Number: 5320-21000-012-01
Project Type: Trust

Start Date: Oct 01, 2006
End Date: Aug 31, 2011

Objective:
1) Optimize chlorate-induced flowering & fruit production in longan; 2) Determine the long-term effect of chlorate application on longan fruit quality; 3) Determine floral induction for "Kaimana" Lychee; 4) Evaluate new lychee cultivars for Hawaii; and 5) Stimulate off-season flowering of lychee.

Approach:
1) Foliar applications of alternative chemicals to chlorate will be evaluated & fruit thinning experiment will be conducted; 2) Soil chlorate levels, plant nutrition, flowering & fruit quality will be evaluated on longan tree after repeated application of chlorate; 3) Artificial cool temperatures will be used to determine floral induction for "Kaimana" lychee; 4) Molecular markers will be used to identify lychee that flower & fruit in Hawaii; and 5) Grafting experiments will be used to transmit floral stimuli from longan to lychee and between lychee cultivars with different floral initiation requirements.
