which lower than those of diploid plants.
This evident indicated a negative correlation between chloroplast number and ploidy level.
Morphological characters of tetraploid plantlets had higher average number of leaves than those
of control. In case of root length, tetraploid plantlets was significantly lower than that of
control. Cytological observation of root tip revealed that tetraploid plantlets had chromosome
number (2n=4x=76) two times higher than those of control (2n=2x=38).
