RESUMO O objetivo do trabalho foi avaliar a adaptabilidade e a estabilidade de genótipos de girassol resistentes a herbicidas do grupo das imidazolinonas em cultivos de segunda safra quanto ao rendimento de grãos e de óleo. Os ensaios foram conduzidos em seis Estados e no Distrito Federal nas safrinhas de 2009 e 2010. O delineamento experimental foi o de blocos casualizados, com quatro repetições. Diferentes métodos foram utilizados para a análise de adaptabilidade e estabilidade. Os métodos de Lin & Binns modificados por Carneiro, Rocha et al. e Porto et al., mostraram resultados similares. O genótipo ALBISOL 20CL apresentou adaptabilidade geral para rendimento de óleo e o genótipo HLA 211CL apresentou adaptabilidade específica para ambientes favoráveis tanto para rendimento de grãos quanto para rendimento de óleo. O método de Porto et al. indicou, para ambientes favoráveis, o genótipo ALBISOL 20 CL quanto ao rendimento de grãos. O método de Eberhart & Russell foi similar aos outros três métodos somente na classificação do genótipo ALBISOL 20CL. Os dois genótipos avaliados mostraram estabilidade tolerável.
ABSTRACT: The aim of this study was to evaluate the adaptability and stability of sunflower genotypes resistant to the imidazolinone herbicides on crops as second crop, related to their grain and oil yield. The assays were conducted in six states and the Federal District in 2009 and 2010. The experimental design was randomized block design with four replications. Different methods were used to analyze the stability and adaptability. The methods of Lin & Binns modified by Carneiro, Rocha et al. and Porto et al. showed similar results. The genotype ALBISOL 20CL presented general adaptability for oil yield and the HLA genotype 211CL showed specific adaptability to favorable environments for grain and oil yield. For grain yield, the method of Porto et al. indicated the genotype ALBISOL 20 CL to favorable environments. The method of Eberhart & Russell was similar to the other three methods only in the classification of genotype ALBISOL 20CL. The two genotypes showed tolerable stability.

Chitosan induces tolerance to abiotic stress agents in plants. However, studies on the diferent application forms of this biopolymer are limited. This study evaluated the efect of two forms of chitosan application on the morphophysiology of and metal accumulation by Talinum patens cuttings subjected to Cd to develop new cadmium (Cd) decontamination technologies. Cuttings from 75-day-old plants were transferred to a hydroponic system. For 30 days, three Cd concentrations (0, 7, and 14 mg L-1) and three forms of chitosan application (without application, root, and foliar) were applied. The cuttings were tolerant to Cd because the metal did not infuence biomass production or photosynthetic efciency. Neither chitosan application nor Cd increased the modifed chlorophyll content and fuorescence parameters. However, foliar chitosan reduced the transpiration rate. At the highest concentration of Cd, the application of chitosan in the root reduced the Mg content of the root system and shoots. The root application of chitosan increased the surface area and volume of thicker roots at the expense of fner ones. The foliar application resulted in greater total root length and surface area, mainly those fner. Furthermore, chitosan applied to the leaves activated catalase in the roots and leaves. In contrast to the root application, foliar application increased the accumulation of Cd in the roots. The action of catalase and the increase of fne roots may have favored a greater absorption of the nutrient solution and Cd in the chitosan foliar application treatment. It is concluded that chitosan foliar spraying can improve Cd rhizofltration with T. patens. MenosChitosan induces tolerance to abiotic stress agents in plants.
