Shedding (abscission)
Time of Update: 2021-03-16
It has been pointed out that leaf aging can lead to its shedding, is due to the reduction of the amount of leaf synthetic growth hormone, through the leaf handle output is also reduced, so that the content of out-of-area growth hormone decreased, this decline can make the out-of-area cells more sensitive to ethylene, causing the effect of the above-mentioned ethylene.

The flow of energy in an ecosystem
Time of Update: 2021-03-16
The energy flow analysis at the ecosystem level is estimated by the total number of individual populations at the same nutritional level, i.e. each population is attributed to a specific nutrient level (based on its primary feeding characteristics) and then the input and output values of each nutrient level's energy are accurately measured.
