,Induction of α-Amylase Synthesis in Aleurone Cells of Barley Grains by Gibberellin,l kinds of plant hormones—auxins, gibberellins and cytokinins—has been rapid in recent years. This experiment is designed to acquaint you with the mechanism of action of one kind of hormone, specifically the gibberellins.

Factors Influencing Enzyme Activity, by the enzyme catalase: $$
m H_2O_2 {mathop{longrightarrow}limits^{Catalase}} H_2O+{1over 2}O_2$$ Activity will be assayed in crude enzyme extracts prepared from spinach leaves by a macro-manometric procedure.
Effects of Auxin and Cytokinin on Morphogenesis in Callus Tissue, new structures and functions and losses of former ones, and temporary spatial and temporal discontinuities and changes in rate. Of course it is quite appropriate to speak of development of individual organs as well as whole plants.
Role of Phytochrome in the Germination of Light-sensitive Lettuce Seeds,ehavior of seed plants literally throughout their ontogeny. Furthermore, phytochrome is by no means restricted to seed plants. It has definitely been identified in certain liverworts and green algae, for example, and there is evidence for the speculation that it probably occurs in all green plants.
Chemical Breaking and Induction of Bud Dormancy,ons which would be adverse or lethal to plants in an active state of growth. Thus, in the case of annual plants, dormancy of seeds is commonplace. In biennials and perennials, dormancy of the buds of established plants and of their seeds and storage organs (e.g. bulbs, corms and tubers) are typical events in the life cycles.

Effects of Ethylene on the Development of Legume Seedlings,velopment in numerous ways. The reason for the hesitation was that ethylene is unique among endogenous growth regulators in being a vapor at physiological temperatures. Thus the metabolism, transport and action of ethylene possess features and involve problems not commonly encountered in hormone biochemistry and physiology.
