The objective of the works was to investigate the effects of
temperature and relative humidity in simulated shipping,
pretreat- ment on the appearance of Ficus microcarpa L.F.var.
nitida Ho dur- ring and after transportation. After 7 and 14
days in 25 and 15℃,leaf yellowing and dropp- ing of Ficus
microcarpa L.F.var.nitida Ho occured, after 10 and 23 days
commercial quality lost, respectively. Plant had only few
foliar abscission and showed good appearance one month after
si- mulated shipping at 10℃. The relative humidity did not
affect the quality of plants in the shipping.One month in
ambient temp- erature and environment after being in 10℃,the
plants recovered and graw normally again and had a fair growing
quality. Plants were chilled when exposed to 5℃ for 3-4 days,
with symptons of necrosis at the margin of young leaves, leaf
wilt and brown necrotic spots on the olderfoliar.Anatomical
examina- tion revealed cell collapse appeared in the parenchyma
cells of epidermal tissue of leaves.Plants pretreated with STS
at or above the concentration of 0.5 mM occured the necrosis
on the leaves. The higher concentration of STS was used, the
more serious the symptoms of necrosis occured.Irrigation
with STS solution at 4 and 2mM before shipping had the effect
of preventing abscission during transportation. However, one
month in ambient temperature after 10℃ storage the appearance
quality had no significant di- fference between treated and
untreated plants.Those plants being removed all leaves could
not recover until two months in ambient temperature. Package in
polyethylene bags with 0.05 and 0.09 mm thickness could
effectively delay the abscission of leaves and mantained
agood appearance during and after the shipment. Post-shipment
acclimatization did not showed any significant effects on
keeping quality of Ficus microcarpa L.F.var.nitida Ho .However,
the acclimatization increased the content of chlorophy- ll a
and b as well as the ratio of chlb/a.
