EFFECT OF HYDRATION-DEHYDRATION CYCLES DURING GERMINATION IN SEEDS OF THE GENUS FEROCACTUS
The germination process for the plant is a risky stage during its life cycle, especially for those belonging to arid zones, such as cacti, which go through discontinuous periods of hydration, therefore, hydration memory is a process vital and a natural adaptation for these plants. In the present work the seeds of: E. grusonii, F. clausen, F. peninsulae, F. pilosus, F. recurvus; of which only the last of these evidenced this phenomenon by expressing germination curves similar to:F. peninsulae, plant that in 2014 the presence of this process was confirmed; temperature, in addition to water, was a limiting factor in the trials, by subjecting the species to different temperatures that affected germination to a greater extent as it decreased.

Abstract:
The germination process for the plant is a risky stage during its life cycle, especially for those belonging to arid zones, such as cacti, which go through discontinuous periods of hydration, therefore, hydration memory is a process vital and a natural adaptation for these plants. In the present work the seeds of: E. grusonii, F. clausen, F. peninsulae, F. pilosus, F. recurvus; of which only the last of these evidenced this phenomenon by expressing germination curves similar to:F. peninsulae, plant that in 2014 the presence of this process was confirmed; temperature, in addition to water, was a limiting factor in the trials, by subjecting the species to different temperatures that affected germination to a greater extent as it decreased.
