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

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 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
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
Ethylene-induced female flower formation experiment
Ethylene alters membrane permeability and cell compartmentalization, and induces the synthesis, release or activation of many enzymes (especially degradative en
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
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 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
