| ABSTRACT: Abiotic stresses and poor biomass accumulation are chief constraints to accomplish potential yield in Leymus chinensis. An experiment was conducted to improve biomass and correlation of biomass accumulating attributes with photosynthetic pigments, osmotic substances and antioxidants under foliar application of different plant growth substances. The experiment was conducted at inner Mongolia Xilinguole, China, using a Randomized Complete Block Design and 5 replications. The treatments consisted of water (control); BA5 = application of BA (6-benzylaminopurine) at 5 mg L-1; BA25 = application of BA at 25 mg L-1; BA50 = application of BA at 50 mg L-1; BR0.02 = application of BR (brassinosteroid) at 0.02 g L-1; BR0.2 = application of BR at 0.2 mg L 1;... |

| Abstract Studies on the effect of the applying of phytoregulators to overcome seed dormancy have been carried out in Annonaceae species, thus the endogenous relationship between abscisic acid and gibberellins after the application of phytoregulators needs to be known in these species. Considering the importance of hormonal balance in dormancy mechanisms, the aim of this research was to elucidate how endogenous ABA and GA concentrations change after the application of phytoregulators in seeds and how these changes affect reserve degradation during germination of Annona macroprophyllata and A. purpurea seeds. Seeds were submitted to three conditions: - no soaking, soaking-in-water and soaking-in-GA4+7+benzyladenine. ABA, GA, lipids, proteins, and total... |

| ABSTRACT: Chemical treatment is a mean to accomplish fruit thinning; although its efficiency depends on the compound used, application time, and dosage. Effect of the chemical hydrogen cyanamide (CH2N2) on the thinning of flowers and fruits of the peach cultivar Coral was assessed in this study. Treatments consisted of five doses of CH2N2 (0, 0.2, 0.4, 0.6, and 0.8%) spray application to the point of run-off, at two stages (50% and 100% flowering). The experiment was conducted in a completely randomized design with six replicates and one plant per plot. The following parameters were assessed: percentage of flowers thinned at 25 days after spraying, percentage of fruits thinned, fruiting index, production per plant, fruit mass, diameter and length, flesh... |

| Dotada de grande resistência à seca, Cnidoscolus quercifolius Pohl (faveleira) é uma espécie que pode ser usada como forrageira, medicinal, alimentação humana, biodiesel e para recuperação de áreas degradadas. Entretanto, apresenta dificuldade de enraizamento pela técnica da estaquia e, por isto, foi avaliada a técnica alternativa da alporquia. Os tratamentos foram constituídos por substratos e concentrações de AIA (ácido indolacético). Foi observado um percentual de 46% de enraizamento no rejeito de vermiculita, com ganho significativo de matéria seca radicular. Não houve efeito significativo das doses de AIA, para as variáveis analisadas. |
