The aim of this study was to compare the gas exchange and some parameters of photosynthesis in primary and tripholiolateleaf of wild and domesticated common bean (Phaseolus vulgaris L.) during early vegetative stage, with de finality of showthe photosynthetic efficiency of wild common bean. Two wild common bean samples from Durango and Tlaxcala, Mexico,and the cultivars Amarillo and Bayo Mecentral were cultivated under greenhouse conditions. Stomatal conductance, CO2assimilation net rate, leave temperature, transpiratory rate, chlorophyll content, and some parameters of the fluorescence ofthe chlorophyll were evaluated. There were statistical interaction between the leave type and common bean variant (wildcommon bean from Durango and Tlaxcala, México, and the cultivars Amarillo and Bayo Mecentral) for chlorophyll a andb, the a/b index, beside initial, variable and maxim chlorophyll fluorescence. A high heterogeneity between and within wildsamples, independently of its origin was observed, the heterogeneity was observed also among the cultivars (Amarillo andBayo Mecentral), id est, a wide interspecific (among species) and intraspecific (within species) variability was found. It wasconcluded that primary and tripholiolate leaf in wild and domesticated variants growing in homogeneous environment showsignificant differences in physiological characters, all of them are diverse between and within wild variants and wild anddomesticates variants evaluated, and conduce to significant differences in PN. |
