Characterization of the morphometry, germination process, phytochemicals, and antioxidant capacity of seeds of three species of the genus Cylindropuntia (Cactacea) of Chihuahua state

Cylindropuntia is a genus of cylindrical cacti found in northern Mexico. This study aimed to describe the fruit and seed morphometry, characterize germination process, as well determine phytochemicals three species from state Chihuahua México: C. imbricata, spinosior, leptocaulis. To measure morphometric parameters, 20 fruits seeds each were used for specie. For characterization two scarification treatments applied, was allowed 42 days. Different parameters process calculated percentage, mean time, speed, speed. The concentration reducing sugars, total phenols, tannins, flavonoids, antioxidant activity (DPPH FRAP), protein content determined under basal conditions. Results revealed significant differences (p ? 0.05) examined, showing imbricata highest values both tissues, followed by those obtained spinosior leptocaulis, respectively. percentage higher leptocaulis (13.3%), although achieved longer time (27.7 days), facing that presented lowest (3.3%), (4.6 speed index (0.024 days). Seeds showed sugar (31.82 mg glucose·g?1 dry weight) DPPH (26.37 CE·g?1of weight), whereas ones phenols (3.08 GAE·g?1 FRAP (11.7 mmol TE·g?1 weight). Besides, value (5.6 protein·g?1). provides first data on information these Cylindropuntia, among them diverse measured.
