The basic and strategic research programs in litchi aim at developing technologies for enhancing productivity, quality, facilitating processing and value addition for increased net returns. The present literature has been, therefore, reviewed to clear the concepts and approaches involving the use of PGRs paving way for future litchi production. Physiological changes such as heavy fruit drop or early abscission in litchi might be due to the lack of hormones needed for the embryo and fruit development, lack of pollination and/or fertilization etc. |
