An essential course for fruit specialization in the department, which deals
with physiological processes and changes such as water relations, water
absorption and its relationship to osmotic potential and water potential,
metabolic processes: photosynthesis, respiration, plant nutrition
(fertilization) and its relationship to physiological activity, the role of
growth regulators and hormones in growth, development, and differentiation Photo
physiology: the relationship of light and heat to flowering and the role of
plant hormones in light responses such as flowering, the ties of
phytochrome to flowering and the vital rhythm of plants, internal growth
factors, plant hormones and their relationship to environmental influences,
dormancy physiology and the relationship of environmental changes to the
phenomenon of dormancy of buds and seeds in fruit trees, and finally the units
of coldness And break the inactivity in the fruit trees.
Successfully completing this course, the student will be able to:
1. The student explains the water relations. for fruit trees.
2. Explains the metabolic processes and the factors affecting them
3. Distinguish between methods of plant nutrition (fertilization) and
their effects on physiological activity
4. Distinguish between the effects of environmental factors on different
physiological processes such as growth, development, differentiation, flowering
in different fruit trees and the factors affecting them.
5. Determine the relationship of plant hormones to the physiology of
trees and the interaction between them and environmental factors such as heat
and light with physiological phenomena such as dormancy and breaking dormancy,
and link theoretical information to the problems that orchids suffer from.
