EFFECTS OF QUALITY OF POSTHARVEST SHOOTS ON FLOWERING AND FRUITING OF LITCHI CHINENSIS 'SHUIDONGHEIYE'
Six-year-old trees of Litchi chinensis Sonn. Shuidongheiye, were used to study the effects of flushing time of terminal shoots and the number of shoots remaining on a postharvest pruning cut on flowering and fruiting of the cultivar. The results of the study showed that the flowering rate of postharvest shoots, which terminally flushed between 25 August and 10 September, 11 September and 25 September, 26 September and 11 October 2008 and thereafter, was 93.33, 85.92, 45.44 and 0%, respectively. All the trees in treatment 1 (one shoot left/pruning cut), treatment 2 (two shoots left/pruning cut) and the control (CK; no shoot-thinning after pruning; 3.55 shoots/pruning cut) produced flowers. The yield of the trees in treatments 1, 2 and the CK was 7.66, 20.85 and 23.76 kg, respectively; the flowering rate of postharvest shoots was 95.46, 89.77 and 78.07%, respectively; the length of postharvest shoots was 57.99, 42.07 and 31.37 cm, respectively; the diameter of postharvest shoots was 0.92, 0.73 and 0.58 cm, respectively; the number of compound leaves of postharvest shoots was 25.6, 16.7 and 12.7, respectively; fruit number/postharvest shoot was 4.09, 5.59 and 3.55, respectively; and fruit number/pruning cut was 4.09, 11.19 and 12.61, respectively. It can be concluded that the best time for the last postharvest flush to grow out is between the end of August and mid-September in Nanning, Guangxi, China.
