| This study aims to verify, accurate and precisely, the responses of Italian ryegrass 'BRS Ponteio' cultivar to different frequencies of defoliation for forage production and especially for seed production. For this purpose, a randomized block design experiment with four replications was conducted. Four frequencies of defoliation were applied (zero, one, two, and three) based on the thermal sum, evaluating the rate of leaf appearance (LAR), phyllochron (P), leaf expansion rate (LER), leaf senescence rate (LSR), stems expansion rate (SER), tillering rate (TR), leaf life span (LL), forage production, proportion of leaf blades, stems plus sheaths, senescent material, and inflorescences, as well as seed production. Second defoliation noticeably altered the... |

| The aimed to evaluate the effect of packages and different environment conditions in the maintenance of physiologic quality of Amaranthus cruentus seeds in the period of 300 days. The seeds used were from the cultivar BRS Alegria indicated for use in Brazilian winter. The experimental design completely randomized in factorial scheme (storage environment × package type × storage period) with four replicates. The amaranth seeds storage in plastic packages, in refrigerator and cold chamber, resulted in better germination maintenance ability. The conditioning in PET package, in natural and cold chamber environments promoted better results in relation to germination. The storage period did not present significant effect for the seeds stored in refrigerator and... |
