Experiments on the effects of growth hormone and ethylene on leaf abscission
The natural regulation of abscission is effected by the inhibitory action of growth hormone supplied from the leaf (or fruit) and the promotional action of ethy
Concentration or potency assay of cytokinin-like substances by the radish cotyledon weight gain method
Cytokinins have the effect of promoting cotyledon enlargement in radish. Over a range of concentrations (0.05 to 50 pp M for 6-BA agonist), cotyledon weight gai
Experiments on the effects of the ripening action of ethylene
Ethylene is one of the five major endogenous hormones and the only gaseous hormone. Almost all plant tissues have the potential to produce ethylene. Ethylene ha
The "triple reaction" experiment with yellowing pea seedlings
Ethylene is a gaseous hormone that has multiple effects on plant metabolism, growth and development. Treatment of yellowing pea seedlings with ethylene gas inhi
Observational experiments on Hill's reaction
Hill reaction (Hill reaction) is a reaction in which isolated chloroplasts of green plants decompose water in the presence of light, releasing oxygen and at the
Observations on the water loss phenotype of isolated leaves of plants and experiments on the determination of their water loss rate
The water loss phenotype of isolated plant leaves and its water loss rate are two important physiological indexes for the study of drought tolerance traits in p
Experiments for the determination of free proline in plants
Plants grown under normal environmental conditions have low levels of free proline, but under adversity (e.g., drought, cold, salt, etc.) the free proline conte
Experimental colorimetric determination of inter-root pH
While absorbing nutrients, the plant root system overflows H+, OH-, HCO3- and other organic substances, which changes the inter-root pH, and thus affects the in
