This course will create awareness of the potential role and their applications of plant growth regulators in Horticultural and agricultural industries. In addition this course will equip students with pre requisite knowledge and skills necessary for the manipulation of plant growth and development processes by using these plant bio-regulators.
Objectives:
At the completion of the course, students will be able to :
Introduction, History, classification of growth regulators (PGRs), Biosynthetic pathways, Source sink relationship in relation to PGR, Occurrence and role of growth regulators in plants, Chemical nature of plant regulators and its relation with physiological activities, Theories of action and interactions of growth regulators, Interrelationships between growth regulators and other organic and inorganic plant substances, Applications in horticulture; growth, propagation, parthenocarpy, flower and fruit thinning, control of pre-harvest drop, fruit maturity, dormancy and storage, seed treatment and weed control, Uses in vegetable and flower nursery, Advances in PGR's.
Practical:
Relevant field and Laboratory studies, surveys and assignments, Study of effects of PGRs in propagation, physiology, growth, flower manipulation, ripening and yield of different horticultural plants.
Learning Outcomes:
Students must have knowledge of various plant growth regulators and their application for growth manipulation.
