Vitis labruscana Bailey) plants in PE house and out house were
used as material. During the growing period,the growth of
shoots, leaves and fruit were investigated. Additionally,the
quality and anthocyanin of fruit, and the cross section,
cholorophyll content and photosynethetic rate of leaves were
compared in both cultural systems . It was found that the
temperature of early spring was elevated higher in the PE house.
The higher temperature was fit for bud break and shoot growth.
The harvest time of PE house grape was a month earlier than that
of out house. However, the microclimate in the PE house somewhat
different from that in the out of house would result in certain
disadvantages in shoot growth and fruit quality. Shorter shoots,
thinner leaves, less fresh and dry weights, lower percentage of
shoot lignification, lower photosynthetic rate, lower total
soluble solids, firmness and coloration of berries were observed
in the PE house grape.
