O experimento foi conduzido na UNESP/Jaboticabal, SP, para avaliar a producao e a qualidade da materia seca (MS) e das sementes da aveia-preta (Avena strigosa Schreb) colhidas em diferentes epocas. A producao de MS, a relacao folha/colmo (F/C), a composicao quimica e a digestibilidade in vitro da materia seca (DIVMS) foram determinadas semanalmente, em plantas colhidas de 14.08 a 11.09.89, enquanto a producao e a qualidade das sementes foram avaliadas de 18.09 a 09.10.89. A analise dos dados revelou aumento na producao de MS nas plantas cortadas de 14.08 a 11.09.89. A relacao F/C, a percentagem de PB e a DIVMS da planta inteira (PI), da folha (F), e do colmo (C) diminuiram, enquanto os teores de FB da PI, da F, e do C aumentaram nas plantas cortadas aos 77, 84, 91, 98 e 105 dias de crescimento. Nao se observaram efeitos das epocas de colheita sobre a producao de sementes; todavia, as colhidas mais tardiamente apresentaram maior valor cultural. Os resultados indicam que a aveia-preta apresenta um ciclo curto na regiao de Jaboticabal. |

Recently, the Brazilian government committed to restore and reforest 12 million hectares of forests until 2030 (Nationally DeterminedContribution - NDC). Seeking to strategically subsidize large-scale restoration policies for Brazil, IPEA and TNC, withthe support of EMBRAPA, the Brazilian Ministry of the Environment - MMA and the Deutsche Gesellschaft fur InternationaleZusammenarbeit - GIZ, developed a study to characterize the main ecological restoration techniques applied in distinct biomesof Brazil. The methodology consisted in identifying widely used materials and management activities. To accomplish that, consultationswere made with project executives, academic experts and public managers from various regions of Brazil. We received 94 responses that contributed to the analyzes performed. The result of this evaluation allowed the description of techniques, foreach Brazilian biome, in terms of the following information: main inputs and activities employed; usual amount of inputs andlabor (man-hours) employed; steps in which each input and activity is used (implementation phase and/or maintenance phase)and a general outline of each technique. Our results show large variability in the characteristics of intensive techniques, wellestablished in the technical and scientific literature (e.g., dense tree planting of several species through seedling), as well as intechniques based on natural regeneration. The expressive number of projects reporting use of the latter (both with and withoutmanagement) highlights the search for efficient results in ecological terms at lower cost and with easier implementation, focusingon natural processes and mechanisms of ecosystems recovery.
