Abstract
Variations in plant dry waight, leAf area., leaf arearatio, leaf dry , specific leaf weight, leaf nitrogen contents, relative growth rate, net assimilation rate and the interrelationships between these characters were obseived o six v&rieties of inung with diverse genetic makeup. The variety Sall.-32 responsive high tofertilization tended to show high 9pe.o.ic leaf weight. and leaf blade nitrogen contend in most of its growth stages iv. compared to other. varktics in the test. The specific loaf weight. and leaf nitrogen contents were highly significant and positively correlated with eaoh other au well as. with ea leulatrd not assimilation rate.
