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
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
Experiments on the growth of pollen tubes and their orientability
Mature pollen falling on the stigma will germinate and grow pollen tubes, and pollen germination can also occur when appropriate conditions (temperature, pH, os
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
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 water content in plant tissues
Water in plant tissues exists in two different states; bound water that is tightly bound to the protoplasmic colloids, and free water that is not tightly bound
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
Experiments for the determination of the total water content of plant tissues
When the plant tissues were in contact with the highly concentrated sugar solution, the bound water remained in the tissues because it was adsorbed by the proto
