the growth of tissue culture plants
order to investigated the growth of tissue culture plants in 1
year-old `Kyoho’ grapevine (Vitis vinifera L.×Vitis labruscana
Bailey), shoot tip tissue culture and cutting plants were grown
in pot and the field of Viticulture Research Sta-tion, NCHU in
summer of 1996, and their growth of shoots, leaves and roots
were investigated in the period from spring to winter of 1997.
Observing the sections of leaf, stem and root via microscope.
It was found that the length and diameter of the shoot, length
of the internode, number of leaves, fresh weight and dry weight
of shoot, total area and weight of leaves of tissue culture
plants were longer, larger and more than those of cutting
plants. The fresh weight of shoot、leaves and root in tissue
culture plant was 1.5 times greater than those of cutting
plants. Tissue culture plants had dark green leaves, thickness
leaves, high levels of cholorophyll, and high levels of
photosynthetic rate. They also had delayed leaf-fall compared to
the cutting plants. By observ-ing the sections of leaf, stem and
root via microscope, it was shown that the array of cells was in
good order and tight. Tissue culture plants were good than those
of cutting plants.
