Abstract
  • Harvesting of seeds at proper stage of maturity is very essential to attain better seed quality. Excellent seed performance could be characterized by the seed viability and vigor, as well as their actual performance in the field. The seed viability of different varieties of Clitoria ternatea, commonly known as blue ternate plants, of five different pod maturities (1 – 100% green pods; 2 - 50% green + 50% brown pods; 3 – 100% light brown pods; 4 – 100% brown pods; 5 – 100% over-mature, twisted brown pods) was evaluated in this study. The study was carried out in a Split Plot Design arranged in Randomized Complete Block Design with four replications. This was conducted at the University of Southern Mindanao, Kabacan, Cotabato, Philippines from February to May 2020. Pod maturity based on the visual color of the pods significantly influenced seed germination. A 100% uniform color of both light to brown pods is a good indicator of higher germination rate. Seeds from over-mature pods with shrivelled and twisted conditions can still germinate but with lower germination percentage rate. The results also imply that even blue ternate pods are still green in color, as long as the seeds are already black, these seeds were already capable of germination, however, at lower germination rate compared to pods which are already brown.
