Oito populações segregantes de feijoeiro (Phaseolus vulgaris L.) foram conduzidas pelo método massal (bulk), no período de inverno, de 1982 a 1984, no Sul de Minas Gerais, visando selecionar progênies adaptadas a essas condições de cultivo. Em 1985 foram selecionadas 450 plantas individuais com base no tipo e número de grãos por planta. A partir de 1986, através de sucessivos ciclos seletivos até 1988, foram mantidas as treze progênies promissoras para o cultivo no inverno, por mostrarem-se tolerantes ao frio, com porte arbustivo, alta produtividade e tipos de grãos aceitáveis pelo consumidor. Entre estas progênies, a ESAL 572 possui peso de 100 sementes com cerca de 25 g, cor roxa, e 6 adaptada principalmente aos ambientes ricos. A ESAL 603 possui peso de 100 sementes em torno de 22 g, cor semelhante A da cultivar Carioca, e 6 adaptada As condições ambientais intermediárias. A1ém desses caracteres, essas duas progênies apresentaram as maiores produtividades de grãos.

Irrigation with microcystins-contaminated water has been shown to cause oxidative stress and negatively affect the development of vegetables. However, the effect of non-microcystins producing cyanobacteria on vegetables is yet to be investigated. In this study, the effects of microcystin-producing (MC?) and non-microcystin-producing (MC-) cyanobacterial (Microcystis aeruginosa) extracts on lettuce (Lactuca sativa L.) and arugula (Erucasativa Mill.) were investigated. Chlorophyll production, peroxidase (POD) activity and selective membrane permeability of the vegetables were monitored after exposure to 0.6?12.5 lg L-1 MC? for 15 days. For MC- extracts, an equivalent biomass of each MC? extract concentration per total MCs concentration was also applied to the vegetables for 15 days. In arugula, exposure to both toxic and non-toxic cyanobacterial extracts resulted in higher POD activity than the control. However, in lettuce plants, significantly lower POD activities were recorded in the presence of MC? and MC- extracts. Although both crude (MC? and MC-) extracts increased plasma membrane electrical conductivity of the vegetables, the effect of MC? extract was higher. Chlorophyll content of both vegetables was not significantly influenced by MC? and MC- extracts. The results of the present study show that vegetables have variable responses to MC? and MC- extracts of M. aeruginosa. Therefore, care must be taken to avoid the excessive use of M. aeruginosa contaminated water to irrigate vegetables, regardless of their MCs production potential.
