Print on Demand. This book explores a series of experiments on the role of temperature in the development of barley. The author studies the development of the barley plant under high and low temperatures, varying the supply of nutrients to understand the relationship between temperature and nutrition on plant growth. The findings reveal a direct correlation between temperature and nutrient availability, impacting the plant's growth and development. These findings contribute to our understanding of the environmental factors that influence plant growth and development, providing valuable insights for optimizing crop production. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

Riassunto

Excerpt from Formative Effect of High and Low Temperatures Upon Growth of Barley: A Dissertation

Gutzeit (5) repeated aderhold's work and found by a rather extensive set of experiments that exposures to temperatures below zero had no effect on stem or shoot production in kohlrabi, beets, or various other plants. He did find, however, that a period at +4° C. During germination and early growth caused about 30 per cent Of Certain beets to produce shoots very early the first year. Some of the shoots produced only very short stems, and the plants were otherwise normal, while other shoots grew continuously and early produced flowers and seeds. Beets of exactly the same kind when kept at 22° C. During germination and early growth showed no shoot production the first year. Only such beets as were pre disposed to early shoot production could be thus forced by low temperatures, so hereditary characters as well as temperature enter in as determining factors. Gutzeit suggests that this temperature response? Explains Why early seeding of beets causes much premature shoot production, whereas late seeding gives little or none. On the basis of other experiments Conducted by himself, as well as data from the literature, gutzeit concludes that low temperatures during germination and early growth favor stem formation, while high temperatures at this time inhibit stern formation.

Appel and gassner (2) noted in the experimental fields of summer cereals at the Agricultural Experiment Station at Dahlem, Germany, a peculiar sickness, the plants becoming light green, and the older leaves turning yellow. Since neither animal nor plant pests seemed to be attacking the cereals, an explanation for their condition was sought in unfavorable soil and weather relations. Greenhouse experiments conducted by appel and gassner led them to attribute the peculiar conditions of these summer cereals to a too high germination temperature.
