BOTANICAL physiology is one of the most instructive branches of science, because it provides an excellent test of a student's capabilities and is particularly suitable for inculcating the spirit of ...

If the evaporation is uniform on a flat exposed leaf, forced convection will also be nearly uniform, and the leaf temperature will vary with the square root of the distance from the leading edge. Then ...

WITHIN the pages of his elementary text-book Prof. Macdougal has collected together a very large number of experiments—so large, indeed, that forty-eight laboratory periods do not by any means exhaust ...

Inexpensive, easy-to-use temperature controllers are able to provide reliable set temperatures for the detailed observation of developmental rates in response to different temperature treatments. A ...

Description: Basic physiological processes of higher plants, particularly as related to the influence of environmental factors on growth, metabolism, and reproduction. Laboratory experiments involve ...

A factorial experiment was designed to study the effects of Mg2+, K+, and Na+ on the growth and biochemistry of Chlorella sorokiniana. Raising Mg2+ or K+ concentration in the nutrient medium increased ...
