When stomata are covered by dust what effects on photosynthesis?
Answers
the process of photosynthesis will get slow
Dust cover on leaves is considered to affect photosynthesis directly, mainly by shading leaf surface, increasing leaf temperature and plugging stomata. This study was carried out to make clear these physical effects of dust on photosynthesis. Four classes of JIS Z 8901 dust (Carbon-Black and Kanto-loam powder Coarse, Fine, Ultrafine), which were different in particle size and had pH values around neutrality, were applied to upper surfaces of leaves of kidney bean and cucumber plants at various densities. These two species were different in stomatal density. Both net photosynthetic rates and leaf temperatures of dusted leaves and clean leaves were measured at the same time, over a range of light intensities.
The following results were obtained both
