In order to relief exported Ficus microcarpa leaves chlorisis and defoliation under dark stress during storage,with F.microcarpa(cion was Thailand banyan) as material and suppling light with fluorescent lamps(28 W),we investigated the effects of different supplemental lighting time lengths(0-12 h·d^-1) on growth and photosynthesis in leaves of F.microcarpa after 28 d simulative storage.The results showed that:(1)When the time of simulative storage was 28 d,the defoliation rate and chlorisis index of F.microcarpa which were supplemental lighting for 0 h·d^-1 were 89.64% and 0.52,respectively.While the treatments with supplemental lighting for 8-12 h·d^-1 significantly decreased defoliation rate and chlorisis index.As compared with supplemental lighting 0 h·d^-1,defoliation rate of the treatments with supplemental lighting for 8-12 h·d^-1 were 35.7%,39.19% and 26.08%,respectively.And chlorisis index were 0.25,0.28 and 0.19,respectively.(2)With the extending supplement lighting time length,relative water content(RWC) of F.microcarpa leaves decreased significantly,while the specific leaf weight(SLW) increased significantly.The Chl a,Chl b,Chl(a+b),carotenoid content,Chl a/b content,net photosynthetic rate(P_n) and stomatal conductance(G_s) increased with the extending supplement lighting time length and the treatments with supplemental lighting for 8-12 h·d^-1 were significantly higher than that of other treatments.While intercellular CO₂(C_i) decreased.(3)Correlation analysis indicated that a significant positive correlation was found between F.microcarpa leaf defoliation rate and chlorisis index during simulative storage.Defoliation rate and chlorisis index were significantly negatively correlated with chiorophyll content and P_n,while they were significantly positively correlated with C_i.And P_n was significantly positively correlated with chiorophyll content and C_i.However it had an outstanding negative correlation to C_i.The study indicated that the measures of supplemental lighting time could significantly decreased F.microcarpa leaf defoliation rate and chlorisis index during storage.The better effect of supplemental lighting time was 8-12 h·d^-1 which were supplied by 28 W fluorescent lamp.Considering the cost,the fittest supplemental lighting time of F.microcarpa should be 8 h·d^-1.And the long time of dark storage condition destroyed photosynthetic system in leaves of F.microcarpa and made them photosynthetic rate decrease.It was the major reason that photosynthetic pigment content which non-stomatal limitation factor decreased.
