In the last years, viticulture has reached a very important role in Brazilian fruit production, not only in temperate zones, but also as an alternative for tropical regions. These different climates require cultivars with wide-ranging production cycles. In Brazil, phytosanitary treatment can reach 30% of production costs. Genetic breeding can play a role in the development of new cultivars with different production cycles and more tolerance to the main fungal diseases. The purpose of this work is to evaluate the phenology and disease incidence of grape accessions of the Brazilian germplasm bank in order to give support to the breeding program. For ten years, 700 accessions were evaluated and classified regarding growth cycle length as very early (0,6%), early (13,9%), medium (43,6%), late (41,8%) or very late (0,3%). In the same period, 1,100 accessions were evaluated for disease resistance. The Brazilian grape germplasm bank maintains resistance sources to the main fungal grape diseases that occur in the country. However, resistance to downy mildew and anthracnose were less widespread in the studied sample. More information about the Brazilian grape germplasm bank can be found on the web (http://www.cnpuv.embrapa.br/prodserv/germoplasma/). These results are assisting the development of new grape cultivars, in order to give support to the evolution and expansion of Brazilian viticulture. |

Three cassava (Manihot esculenta) genotypes were grown in greenhouse conditions and subjected to water deficit treatments to: (a) assess the extent to which abscisic acid (ABA) and osmotically active solutes accumulate in cassava leaves during water deficit and solute contributions to osmotic adjustment (OA), and (b) determine whether cassava leaves substantially increase their content of dehydrin-like polypeptides during water deficit. The concentration of ABA, sugars (sucrose, glucose, and fructose), proline, and potassium salts (K-salts) were determined in mature and expanding leaves. ABA content increased under water deficit, consistent with a putative role in regulating solute accumulation, and thus OA. The extent of osmotic adjustment, although modest, was higher in young folded leaves than in mature leaves. K-salts were the major contributors to total osmolyte concentration in both mature and expanding leaves, accounting for approximately 60% of osmotic potential. The concentration of K-salts increased in response to water stress and was positively correlated with the extent of OA. In contrast, total sugars (sucrose + glucose + fructose) decreased during water deficit, showing a negative correlation with OA. Although the concentration of proline in mature leaves increased in response to water stress its contribution to the total change in osmotic potential was insignificant. Thus, in the current study, cassava used K-salts as its primary osmolyte, and did not substantially adjust its osmotic solute concentration during the 6-day water deficit. Expression of dehydrins was not found in any of the genotypes or leaf stages.
