Abstract:
To date, the application of micropropagation technology for increasing the quality and
stock plants are world-wide recognition. By using tissue culture technique with
correlation of Cryptocoryne elliptica at certain salinity, these will improve the
productivity of stock plants. The objectives of this study were to determine the effect
of different concentrations of NaCl on the growth and chlorophyll content of C.
e/liptica cultures. C. elliptica cultures were treated with different concentrations of
NaCl at 0, 25, 50 and 100 rnM in B5 solid medium. The growth and chlorophyll
content were determined at 0, 1, 2, 7, 14 and 28 days of treatment periods. The
chlorophyll content of C. elliptica cultures were initially reduced and longer treatment
periods tend to increase the chlorophyll content. The chlorophyll content in control
plants was significantly higher than the treated cultures especially at higher
concentration of NaCl. Longer NaCl treatment periods significantly increased the leaf
length of C. el/iptica cultures.
