| ABSTRACT: Among the species related to sugarcane, Saccharum spontaneum (L.) is a wild species with the greatest potential as a source of genetic variation to cope with biomass production in harsh environments. Due to its high yield, early vigor, ratooning ability, low input requirements and tolerance to various biotic and abiotic stresses, sugarcane breeders have shown interest in its contribution, as a donor of genes, to the development of high biomass energy canes. The conservation, evaluation and utilization of the genetic variability of S. spontaneum available in germplasm collections are critical for breeding, but, given the aggressive rhizomatous growth habit and the ability to propagate via seed dispersal, S. spontaneum is classified as a noxious... |

| The objective of this study was to compare the gas exchange, photosynthetic capacity and water potential of sugarcane genotypes cultivated under water deficit conditions imposed during the initial growth phase. Experiments were performed in a greenhouse using two sugarcane genotypes namely: HoCP93-776 (drought susceptible) and TCP02-4587 (drought tolerant). Sixty days after planting, two different water treatments were applied (i.e., with or without water deficit). At 0,30 and 60 days after the treatment, gas exchange variables were evaluated for their relationship with water use, intrinsic instantaneous water use efficiency and instantaneous carboxylation efficiency. The SPAD index, photosynthetic pigments, water potential and relative water content in... |

| Water deficit is one of the major factors limiting the production of sugarcane (Saccharum officinarum L.). A study of the effects of limited water condition on yield components and their relationship with productivity can aid breeding programs in selecting for high yielding genotypes under this condition. The objective of this study was to investigate the relationships among the parameters stalk number, stalk height, stalk diameter, and stalk weight with cane yield in sugarcane growing in a field under moderate water stress during its grand growth period, in order to provide information to help breeders in adopting traits for selecting drought tolerant varieties. Seventy-eight genotypes plus two controls, one drought-tolerant and one drought-susceptible,... |
