No CPAA estao sendo desenvolvidas pesquisas com enxertia de copa (painel de alta producao enxertado com copa de clone altamente resistente) com o objetivo de viabilizar o controle do mal-das-folhas. Estao sendotestadas combinacoes de clones de alta produtividade com copas de Hevea pauciflora. O estudo da influencia das copas enxertadas sobre os parametros fisiologicos do latex mostra que o efeito depressivo manifesta-se principalmente pela reducao da duracao do escoamento. Combinacoes com paineis de escoamento mais facil sofrem menos efeito depressivo e atingem niveis de produtividade, no teste HMM, comparaveis aos resultados obtidos em testes precoces feitos em clones da Asia e Costa do Marfim, que, na fase adulta, produzem 2t/ha/ano. Alem do Microcyclus ulei, os clones de Hevea pauciflora sao resistentes ao Phyllachora huberi. |

Abstract: Plant growth-promoting substances have been commercialized in agriculture, especially synthetic hormones such as kinetin (KIN), gibberellic acid (GA3), and indole-3-butyric acid (IBA). However, few studies proved the agronomic effect of these substances on the main crops. The objective of this work was to evaluate rates and methods of application of a hormonal plant growth promoter (HPGP −0.09 g L−1 KIN, 0.05 g L−1 GA3, and 0.05 g L−1 IBA) and their effects on wheat grain yield and nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) uptake. The research was carried out in Londrina, Brazil. A randomized block design was implemented, considering a 2 × 3 × 4 factorial arrangement. It was composed of two genotypes (BRS Gralha?Azul and BRS Sanhaço), three HPGP rates (0, 5, and 10 mL kg−1) applied on the seeds, and four HPGP rates (0, 0.25, 0.5, and 1 L ha−1) sprayed on the leaves. Applications of HPGP did not change grain yield, density of fertile plants, lodging, plant height, aboveground dry matter (AGDM); P, Ca, and Mg concentration in the AGDM; and P, K, Ca, and Mg utilization efficiency (UE). In 2016, the application of 5 mL kg−1 HPGP on the seeds (without HPGP on the leaves) increased by 20.9% the N concentration in the AGDM. In 2017, NUE increased up to 21.2% in response to HPGP sprayed on the leaves. The diversity of interactions among genotypes, HPGP application techniques, and weather conditions hinders the assertive use of the product by farmers.
