The book summarizes present scientific knowledge in plant physiology with regards to plant production. The authors, mainly professors of plant physiology at agricultural universities in Czechoslovakia, present the individual fields of plant physiology with regard to the demands of agricultural practice and education of students and doctorani at these universities.
The first chapters discuss metabolism ie. photosynthesis, respiration, mineral and heterotrophic nutrition, and water regime of plants. What follows is a discussion of the physiology of plant growth, development and movements, and finally resistance of plants against unfavourable abiotic and biotic effects.
The book shows how to increase the yield of crops by manipulating photosynthesis and also studies the possible flow of photosynthetic products to the commercially valuable parts of the biomass. Rational plant production, however, cannot do without knowledge of plant nutrition and water regime as a theoretical basis for fertilization and irrigation. The reader will find this knowledge detailed as well as information about the ecological and physiological principles of the resistance of plants against drought, frost, heat, diseases and other unfavourable effects.
