Some Seed Traits and Their Relationships to Seed Germination and Field Emergence in Pea ( Pisum sativum L.)

摘要

This study investigated relationships among some seed traits, laboratory germination percentage and seedling emergence under field conditions in pea ( Pisum sativum L.) cultivars. Jumbo, Jof, Green Pearly, Agromar AG-7306, Bolero, and Karina pea cultivars were used. It was determined that 100 seed weight negatively and highly significantly correlated with laboratory germination and field emergence percentages. Pea cultivars with high seed coat ratio gave lower electrical conductivity values than lower ones and their laboratory germination percentage s were significantly higher. Electrical conductivity values showed positive and highly significant correlation with 100 seed weight, while it negatively and highly significantly correlated with laboratory germination and field emergence percentages. It was also found that emergence periods were prolonged with increases in electrical conductivity values and 100 seed weight.
