Laser technology sorting method can improve Capsicum pepper seed quality
Date:10/21/2013

Capsicum cultivars at four fruit harvest dates: orange (immature), bright red (half mature), dark red (mature), and dark red and soft (over mature). Seeds were either sorted or non-sorted after harvesting, and standard laboratory germination, seedling emergence, and controlled deterioration tests were conducted. Results showed that chlorophyll fluorescence sorting significantly increased laboratory germination, seedling emergence, and seed vigor. The scientists found that maximum improvements were obtained from seeds harvested from half-mature and mature stages.

"While previous studies evaluated seed quality solely based on laboratory germination tests conducted under optimum germination conditions, our work tested the effect of CF sorting not only on laboratory germination, but also on emergence and physiological aging as indicators of seed vigor," said corresponding author Burcu Begm Kenanoglu. "The results showed that CF sorting affects germination and seed vigor. In our work, CF worked on the four cultivars examined, and this shows that the method may be well suited for Capsicum annuum. Chlorophyll fluorescence has the potential to upgrade seed quality in pepper lots as a nondestructive sorting technology."
