Types of crop stress
From the germination of the seed to the senescence phase, the plant develops vegetatively and reproduces, passing through a series of stages that make up its biological cycle.
The stress factors coincide with the biological stages
Stress factors may coincide with the critical stages of embryogenic development
When plants enter these different phases is genetically determined and depends on environmental conditions.
The starting signal common for each process is a change in the endogenous contents of the hormones, which are followed by changes in how the metabolites are distributed internally in the plant. These sensitive phases also coincide with the critical states of the crop to attain optimal production.
