| The study aimed to evaluate the influence of overcoming dormancy of seeds of biribá through chemical and mechanical method in the emergence and initial growth of seedlings. The fruits were acquired from a mother plant in Cascavel (PR). The experimental design was a completely randomized in factorial 2 x 3, with four repetition, containing 25 seeds each repetition. The first factor was constituted of scarification with sandpaper n.80 of the two sides opposite the micropyle (with and without), the second factor was the soaking for 24 h (water, GA3 in the concentration of 1000 mg L-1 and without soaking). The count was performed for up to 60 days, being calculated the emergence speed index, average time of emergence and speed of emergence. When the... |

| 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... |

| The objective of this study was to evaluate the production of seedlings of Physalis L. species under different-colored shade nets. Four shade nets individually stained white, blue, red and black, all with 50% shading, were used in this study, and an additional treatment (control) was used in which seedlings were grown in full sun. The study examined four species of Physalis, namely, P. peruviana, P. pubescens, P. minima and P. ixocarpa. The experiment followed a randomized block design with three blocks and 25 seeds per plot. The species were sown in styrofoam trays. Germination was monitored daily to calculate the Emergency Velocity Index (EVI) and stabilize the overall percentage of emergence. Height, stem diameter, number of leaves, leaf area index and... |
