Foi conduzido um experimento na Universidade Federal de Lavras, em Lavras-MG, com o objetivo de avaliar a mobilização de reservas de sementes para as plântulas de seringueira (Hevea spp.). Aos 0, 7, 15, 30 e 50 dias após a recipagem, as plântulas, separadas em parte aérea e raízes, e as sementes (até o 30 dias) foram coletadas, secas a 70 C/72h e, posteriormente, pesadas. Determinou-se o teor de minerais nas sementes. As reservas orgânicas e minerais foram mobilizadas, com excessão dos minerais Ca, Fe e Mn. Mobilization of reserves in rubber tree seeds (Hevea spp.) An experiment was carried out in Universidade Federal de Lavras, State of Minas Gerais, Brazil, with main aim to evaluate mobilization of reserves from the seeds to the rubber seedlings (Hevea spp.). After 0, 7, 15, 30 and 50 days of experiment, the seedlings were separated into roots, shoots, seeds (these only up to the 30th day) and submitted to drying at 70 c/72h. Then, they were weighed. The macro and micronutrients content was determined. The organic and mineral reserves were mobilized, expect Ca, Fe and Mn. |

Old vineyards may present high copper (Cu) content in the soil due to the frequent application of Bordeaux fungicide to control leaf fungal diseases. Thus, many wine makers replace copper fungicides by those made of zinc (Zn) and it leads to the accumulation of these two elements in vineyard soils, fact that may potentiate the occurrence of physiological disorders and morphological changes in the plant root system. The aim of the current study was to assess the effects of high Cu and Zn contents in a sandy acid soil on the physiological state and development of the root system in young grapevines. The soil was taken from a vineyard from Southern Brazil, and then it was sieved and had its acidity and P and K contents corrected. Next, the soil was subjected to the application of 0 and 120 mg Cu kg?1 ; each one of these doses was added with 0, 120 and 240 mg Zn kg?1 , thus totaling six treatments. After the treatments were added to the soil samples, 2.4 kg of soil was stored in rizoboxtype containers. One young grapevine plant was transplanted to each box. The transplanted plants were cultivated for 60 days in greenhouse. The accumulation of root and shoot dry matter was set after the experimental period, as well as the Cu and Zn contents in the roots and shoot, the root system morphology, the chlorophyll a fluorescence, the photosynthetic pigments, the gas exchanges and the superoxide dismutase enzyme activity (SOD). Young grapevines presented mechanisms to tolerate high Cu and Zn concentrations in the soil, mainly through the retention of such metals in their roots to diminish translocation to the shoot. However, the highest Cu and Zn doses led to grapevine plant growth decrease, to gas exchange alterations and to photochemical efficiency reduction associated with photosynthetic pigment decrease and to non-photochemical energy dissipation increase. Moreover, the SOD activity was greater in intermediate Zn doses, thus indicating antioxidant system activation. Thus, the combination between high Cu and Zn concentrations in vineyard soils will enable minimizing the toxic effects of these metals to young grapevines cultivated in these soils.
