2007 Annual Report

1a.Objectives (from AD-416)
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.

1b.Approach (from AD-416)
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. (Documents Trust agreement with UH Hilo. 425 log 31540)

3.Progress Report
This report serves to document research conducted under a trust agreement between ARS and the University of Hawaii, Office of Research Services. Additional details of research can be found in the report for the parent CRIS 5320-21000-009-00D 'Assuring long-term preservation of tropical crops via genetic resource management. No significant research has been made for this project since funding was not received until August 2007.
