Effect of Soil Types Upon Growth and Variation in Oats (Classic Reprint) - Softcover

Inhaltsangabe

Excerpt from Effect of Soil Types Upon Growth and Variation in Oats<br/><br/>It has long been contended by various investigators that soils and climate are the main causes of environmental variations among plants. But it is not yet definitely known whether differences in amount of plant food or other soil conditions produce important permanent changes in habit; that is, mutations. Of the two factors, climate seems to be the more effective in producing variations in physical structure as well as chemical composition of the plant. This matter has received considerable attention by investigators especially in connection with the protein content in wheat. The study of the effect of environment upon the morphology and anatomy of plants has received relatively little attention. It perhaps more properly belongs to the realm of the ecologist but the problem is so closely related to plant breeding as to be practically inseparable.
