Biometry and storage of Triangle Palm seeds

Abstract Studies on biometry are considered important tools for understanding the germination process of seeds. Moreover, ex-situ conservation palm seeds can cause loss viability over time. The present study aimed to evaluate biometric characterization and effect storage seed Triangle Palm (Dypsis decaryi), a widely used species in Brazilian landscaping. Two independent studies were conducted: I) diaspores II) germination. For biometry, sample 100 was length, width thickness measured. Biometric data analyzed using descriptive statistics correlation analysis. packed transparent plastic bags kept refrigerator (20 ± 2 ºC 80% relative humidity) evaluation. experimental design entirely randomized. treatments consisted six periods (0 - control, 30, 60, 90, 120 150 days); there four repetitions 25 per plot. percentage speed index evaluated. Diaspores showed little variation their characteristics, with mean 18.39 mm 16.10 15.96 thickness. There significant positive between all characteristics. It observed that remained stable until 30 days (90%), gradual decrease later periods. allowed maintain its longevity ability germinate, reaching 63% after storage.
