greater the leaf area
in plant, maximum plant growth and photosynthetic
ability which provide greater dry and fresh weight to
plant (Khan and Khalil, 2010). In the present study,
different leaf areas at different temperature levels were
observed in Panicum species. Panicum coloratum
showed maximum leaf area as compared to other species
of it proved that it have more tolerance for heat (Figure
3). Maximum leaf area in Panicum coloratum showed
that it give up highest fresh and dry matter as compared
to other Panicum species because increasing leaf area
result in forceful photosynthetic ability and plant growth
