Assessment of Seed Vigor Tests for Crambe abyssinica

Journal of Agricultural Science, 2018
Vigor tests are important mainly to identify differences associated to lots performance in field conditions. The objective of this study was to define the most appropriate tests to evaluate the crambe (Crambe abyssinica) seeds vigor. Seven seed lots of crambe were subjected to the standard germination (on the first and last count), germination speed ...

Controlled deterioration test for evaluation of sunn hemp seed vigor [PDF]

Journal of Seed Science, 2015
The controlled deterioration test is efficient for seed vigor evaluation of several species. However, the procedures conditions are incipient, especially in respect to tropical forages such as sunn hemp, which still does not have a standardized procedure. The objective of this research was to adjust the procedures for a controlled deterioration test in
