Sensitivity of yellow passion fruit plants to ultraviolet-B radiation

The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted UV-B radiation near the apex of the plants was 8 W m-2 for the UV-B treatment (high UV-B), and 0.8 W m-2 for the control plants (low UV-B). Plants were irradiated with UV-B for 7 hours per day, centered on solar noon, during 16 days. High UV-B radiation resulted in lower shoot dry matter accumulation per plant. The content of UV-B absorbing compounds and anthocyanins was increased in the plants exposed to high UV-B radiation, when compared with the control. UV-B radiation did not affect stomatal conductance or transpiration rate, but reduced photosynthesis and instantaneous water‑use efficiency, and increased intercellular CO2 concentration. The accumulation of UV-B-absorbing compounds and anthocyanins did not effectively shield plants from supplementary UV-B radiation, since the growth and photosynthetic processes were significantly reduced.

Relação K:Ca:Mg na solução nutritiva para produção de minitomate cultivado em substrato

The study was conducted to evaluate six K:Ca:Mg ratios for production of two cultivars of mini tomato grown in substrate, in a greenhouse, during two growing seasons. The experimental design was randomized blocks with four replications and twelve treatments using both cultivars of mini tomato (Sweet Million and Sweet Grape) and six K:Ca:Mg ratios (4:3:1, 6:3:1, 6:4.5:1, 2.7:3:1, 2.7:2:1, 4:2:1) in nutrient solutions. In both experiments, nutrient solutions with the highest concentrations of Mg, (75 mg L-1) and the lowest concentrations of Ca, (150 mg L-1) led to the highest concentrations of those nutrients in plant dry matter. The Sweet Million cultivar had higher yield (1.69 kg plant-1 and 1.52 kg plant-1), number of fruits per plant (227 and 236), and water use efficiency (29.1 kg m-3 and 25.3 kg m-3). However, the Sweet Grape cultivar had fruits of higher mean weight (9.0 g and 8.8 g) and macronutrient content in the leaves. In both crop cycles, the different K:Ca:Mg ratios affected only the macronutrient contents of the mini tomato plants grown in substrate, with no effect on yield and water use efficiency. The first crop cycle showed the highest N, K, Ca and S content.

Use of the freshwater crab Trichodactylus fluviatilis to biomonitoring Al and Mn contamination in river water.

Determinations of Al and Mn concentrations in the tissues (gills, hepatopancreas and muscle) of the freshwater crab Trichodactylus fluviatilis and water samples, both collected from sites on tributaries of the Corumbatai River (São Paulo, Brazil) were performed. The Bioaccumulation Factor (BAF), calculated for different sites with respect to the water concentration, ranged from 173-555 for Al and from 636 - 921 for Mn. Dissolved concentrations of Al and Mn in water samples (collected in different sites) were related to the accumulation of these metals in crabs, suggesting that T. fluviatilis is good biomonitor for Al and Mn pollution in aquatic ecosystem.
