Efeitos da carência de alguns nutrientes minerais no desenvolvimento de plantas de soja (Glycine max (L.) Merrill cv Santa Rosa)

The present work studies Ca, B and Zn omission on the development of soybean plants (Glycine max (L.) Merrill cv Santa Rosa). The experiment was carried out as hydroponic culture, with complete Hoagland & Arnon nutrient solution nr. 2 (C), lacking calcium (-Ca), lacking boron (-B) or lacking zinc (-Zn), a total of 4 treatments. Seven samplings were made to determine: total dry matter (g), root dry matter (g), stem dry matter (g) and leaf dry matter (g). Results showed that Ca and B omissions decreased dry weight. Lack of Zn did not affect dry weight.

Effect of type of cuttings and indolbutyric acid on the rooting of rose (Rosa sp. 'Red success') leafy cuttings during two seasons

The objectives of this study were to evaluate the effect of type of cuttings (apical, intermediate and basal) and different concentrations of IBA (indole-3-butyric acid) on rooting of Red success rose (Rosa sp.) leafy cuttings, during two season of cuttings collection (summer and winter). The investigation was carried out in the farm Irmaos Van Schaik in Holambra-SP, Brazil, from February to April and August to October/1993. The experimental design was a randomized block in a factorial arrangement. It consisted of 12 treatments (3 types of cuttings combined with IBA powder in 4 different concentrations - 0, 1000, 2000 and 4000 ppm) with 3 replicates during 2 seasons. The investigation permitted the following conclusions: the apical and intermediate cuttings showed better results in general when compared to the basal ones in both seasons; the average rooting at the transplanting time were 76%, 70% and 47% (summer) and 80%, 69% and 33% (winter) for apical, intermediate and basal cuttings, respectively; the utilization of IBA did not stimulate rooting. The average rooting for the control cuttings reached 85% (summer) and 78% (winter), regardless the type of cuttings.

Effects of rooting media, indolbutyric acid and fertilization on the rooting of rose (Rosa sp. 'Dalas') leafy cuttings

The objectives of this study were to evaluate the effects of rooting media (vermiculite, carbonized rice bark, fenolic spume and sand), presence of IBA (indole-3-butyric acid) and presence of fertilization during the rooting of rose (Rosa sp.) leafy cuttings, Dalas cultivar. This investigation was carried out in Jaboticabal (Sao Paulo State - Brazil) during the period of March to April 1997. The experimental design was a randomized block in a factorial arrangement. It consisted of 16 treatments (the 4 rooting media combined with IBA concentrated solutions - 0 and 1.000 ppm and fertilizer - 0 and commercial product with macro and micronutrients, applied weekly) with 3 replicates. The evaluations were 30 days after cuttings showed that the best rooting percentage occurs in sand (98%), followed by vermiculite (90%) and fenolic spume (87%) and cuttings treated with IBA (95%), while the fertilization showed no promoting effects. The number of cuttings roots wasn't affected with rooting media or DBA treatment, while the fertilization showed effective.

Morphologic characterization and evaluation of the productivity of nine rootstocks of rose bush (rosa spp.)

In Brazil, garden and cut rose bushes are propagated through cuttings or grafting. The rootstocks used in most of the traditional areas of cultivation are not identified, being known just by the vulgar name. There is not any information in the literature on the morphologic characteristics, nor about the productivity of different cultivars on the rootstocks available in Brazil. The objective of this work was to characterize and determine productivity of nine rootstocks (Rosa multiflora 'Paulista'; R. multiflora 'Japones'; R. multiflora 'Iowa'; R. multiflora 'Kopmans'; R. indica 'Mayor'; R. indica x multiflora; R. sp. 'Natual Brier'; R. manetti and R. canina 'Inermis') grafted with 'Versilia' and 'Tineke' scions. Morphologic studies were undertaken to characterize branches of adult plants to determine shape and dimensions of the leaf; number of prickles/15 cm of stem; vigor of the stems; incidence of Diplocarpon rosae (blackspot) and coloration of the leaf. The productivity (number of commercial flowers/plant/month) was evaluated for 6 months (October, 2000 to March, 2001), in the city of Andradas, Minas Gerais State, located at 1251 meters above sea level. Since there was significant difference in just two months for both rootstocks, 'Tineke' and 'Versilia', no rootstocks could be considered inadequate. Nonetheless, in general, the rootstocks that showed a better performance with 'Tineke' were, R. multiflora 'Kopmans' and R. manetti and with 'Versilia', R. multiflora 'Kopmans' and Rosa sp. 'Natual Brier'.

O impacto da pesca do camarão-rosa Farfantepenaeus paulensis (Perez-Farfante) (Decapoda, Penaeidae) nas assembléias de peixes e siris do Parque Nacional da Lagoa do Peixe, Rio Grande do Sul, Brasil

This work evaluates the impact of the pink shrimp Farfantepenaeus paulensis (Perez-Farfante, 1967) fishery on fish and crab assemblages of Lagoa do Peixe National Park, Brazil. We observed that composition of catches is similar to shrimp fisheries using fyke-net at others estuaries of Rio Grande do Sul State: pink shrimp (53%), accessory catches (24%) and bycatch (23%). However, fishery composition showed distinct differences along the saline gradient of the main park's lagoon. Regarding only fish species, the most impacted species in this fishery were Brevoortia pectinata (Jenyns, 1842), Micropogonias furnieri (Desmarest, 1823), and Jenynsia multidentata (Jenyns, 1842). In others estuaries from Rio Grande do Sul, in contrast, the most impacted species were M. furnieri, Genidens barbus (Lacepède, 1803) and Genidens genidens (Cuvier, 1829). The potential impact of the pink shrimp fishery at Lagoa do Peixe National Park seemed to be weaker when compared to shrimp fisheries elsewhere. We believe that the decision to prohibit this fishery at the Lagoa do Peixe National Park should not be based on its potential damage to the fish and crab assemblages but based on the simple fact that Brazilian laws do not allow fisheries inside National Parks.

Crescimento e sobrevivência do camarão-rosa (Farfantepenaeus paulensis) na fase de berçário em meio heterotrófico

The objective of the present study was to evaluate the potential of a heterotrophic rearing media (microbial flocs) on the growth and survival of Farfantepenaeus paulensis reared in the nursery phase. For 30 days, F. paulensis post-larvae (0.019 ± 0.01g) were reared in nine 40-liter plastic tanks at the density of 500 post-larvae m -2. Three treatments with three replicates each were used: rearing in the presence of microbial flocs with ration supply (FLOC + R); rearing in the sole presence of flocs - no ration supplied (FLOC); and rearing in clear water plus with ration supply (AC + R). The presence of microbial flocs had no significant effect on growth and survival in the nursery rearing of F. paulensis.
