| Abstract Rocoto pepper (C. pubescens), is one of the domesticated species of the genus Capsicum in South America. Currently, its supply and demand are arising in national and global market. The aim of this study was to determine the optimal extraction timing of the seeds of C. pubescens according to physiological and physical seed qualities. Seed qualities measurement include seed weight, number of seeds per fruit, total emergence, emergence rate, mean emergence time, mean daily emergence, survival percentage, peak value and emergence value. Treatments were evaluated for comparison as follows: seed extraction ranged from 0 to 3 days after harvest (T1), and seed extraction ranged from 14 to 17 days after harvest (T2). T1 presented seeds with the best... |

| Abstract The dry Andean forests are ecosystems with a high diversity of flora and fauna and are at high risk of extinction due to the pressure of human activity. V. macracantha is a native species of the dry Andean forest, which has potential for reforestation and also provides benefits in agroforestry systems, due to its nitrogen fixation capacity, the supply of organic matter, the production of shade and wind protection. The multiplication of this species is limited due to the low percentage of seed germination, which present dormancy. The aim of this research was to determine the most effective scarification method for seeds germination of V. macracantha. Two types of methods were tested, the immersion in strong acids (chemical scarification), and the... |
