Capim-annoni 2 (Eragrostis plana Ness) é uma gramínea originária da África, que foi introduzida acidentalmente no Brasil na década de 1950. A espécie possui alto teor de fibra e baixa digestibilidade sendo pouco consumida pelos animais. A alta dispersão sobre as pastagens suprime as demais espécies de interesse forrageiro. A recuperação de pastagens é difícil e requer a integração de vários métodos, como a redução da radiação solar através do sombreamento por espécies de porte alto. O presente trabalho pretende conhecer a morfogênese da invasora sob duas densidades populacionais de plantas. Pretende-se gerar uma recomendação técnica para manejo e controle. |

Control of the vegetative growth of deciduous fruit plants has been a major concern of producers for many years. The vigorous growth of the aerial part negatively affects the quality of the fruits due to the reduction in the distribution of the light inside the canopy necessary to improve the fruit color, besides making difficult to handle diseases. In this context, the adequate
balance between the vegetative and reproductive development of the plants can maximize the productive efficiency and fruit quality in temperate fruit plants. In recent years, research results indicate the feasibility of using growth regulators in canopy management, making it possible to reduce the amount of plant material, especially the shoot, allowing the translocation and
use of photoassimilates for leaves and fruits. Inhibitors of gibberellin synthesis and ethephon can be used for this purpose in various fruits, but information on grapevine cultivation is limited. The objective of the work was to evaluate different growth regulators in the control of vegetative development and increase in the yield of 'Cabernet Sauvignon' vine. The experiment
was carried out in a vineyard located in Videira, Brazil (27°06'67"S, 51°14'86"W and at an average height of 1,000 m), in the 2017/2018 crop year, using the cultivar Cabernet Sauvignon, Vitis vinifera L., with 5 and 6 years old, grafted on 'VR 043-43' rootstocks. The following treatments were tested: 1. Check (untreated plants) ; 2. Trinexapac-ethyl (TE) - 100 ml.100 L-1 at
full bloom (FB); 3. TE - 100 ml.100 L-1 at 75 (days after full bloom - DAFB); 4. Prohexadione calcium (PCa) - 28 g.100 L-1 at full bloom (FB)+ 28 g.100 L-1 at 15 DAFB; 5. PCa - 28 g.100 L-1 at 75 DAFB + 28 g.100 L-1 at 90 DAFB; 6. PCa - 74 g.100 L-1 at full bloom (FB); 7. PCa - 28 g.100 L-1 + Etefon 100 ml. 100 L-1 at 75 DAFB; 8. Naphthalene acetic acid (NAA) ? 3,3 ml. 100 L-1 + Etefon 100 ml.100 L-1 75 DAPF. A randomized complete block design with six replicates of one plant per plot was used. Data were analyzed by one-way ANOVA. For multiple comparison procedures between means, Skott Knott tests (α = 5 %) were performed using SISVAR 5.0 program. There were no differences between treatments regarding: shoot length, number of
clusters per plant, number of berries/cluster and cluster length, fresh and dry mass of rachis, soluble solids content and total acidity. All growth regulators, when applied 75 DAPF, increased yield per plant while PCa and TE applications, in full bloom, reduced the size and mass of the berries when compared to the control. The application of PCa 75 DAPF also reduced the pH
of the juice (3.04). Under current experimental conditions, the product was not effective in reducing vegetative growth, however, when applied at veraison increased yield per plant. The results of this study demonstrate promising effects of ethylene treatments, with higher production and no reduction in berries quality.
