RESUMOO estresse hídrico ao longo do ciclo da cultura do rabanete pode interferir no seu desenvolvimento, causando alterações na morfologia, fisiologia, e impossibilita as reações bioquímicas da planta. O objetivo desse trabalho foi avaliar o desenvolvimento, as características morfológicas e a produtividade do rabanete submetido a diferentes lâminas de irrigação na fase de produção da cultura. O presente trabalho foi desenvolvido no setor de olericultura da fazenda experimental do campus da UFMG em Montes Claros-MG, no período de abril e maio. O delineamento experimental foi em blocos casualizados onde foram montadas 16 parcelas e a partir do 21º dia as parcelas foram submetidas a 4 tratamentos e 4 repetições cada. Estes tratamentos consistiram em 4 lâminas de irrigação sendo elas de 50 %, 75%, 100% e 125% da ETo. Avaliou-se o diâmetro do caule (mm), diâmetro do bulbo (mm), peso (grama), temperatura em °C, número de folhas, altura (cm), teor de clorofila. As lâminas de irrigação não apresentaram efeito significativos nas variáveis: número de folhas, temperatura, teor de clorofila e diâmetro do caule. Já a altura da planta, o diâmetro e o peso do bulbo tiveram aumento com a Lâmina de água, sendo esta relação linear. Portanto, as lâminas de irrigação apresentaram efeito crescente no desenvolvimento e produtividade. Palavras-chave:Raphanus sativus L., olericultura, hortaliça, água. MORPHOLOGICAL AND PRODUCTIVE CHARACTERISTICS OF THE RADISH UNDER DIFFERENT IRRIGATION BLADES ABSTRACTWater stress throughout the crop cycle of the radish may interfere with its development, causing changes in the morphology, physiology, and the biochemical reactions of the plant.

the growth process and root quality. However, few studies are evaluating the influence of the interaction between nutrients in this culture. The objective of this work was to evaluate the effects of the combination of nitrogen fertilization with boron on the production characteristics and quality of the beet Tall Top Early Wonder. The experiment was carried out at the São Manuel Experimental Farm (FCA/Unesp), located in São Manuel-SP. The experimental design was in randomized blocks, with four replications. The evaluated factors were: nitrogen and boric fertilization, in the factorial scheme (2 x 2), totaling 4 treatments: T1 (0 kg ha-1 of N and 0 kg ha-1 of B), T2 (0 kg ha-1 of N and 4 kg ha-1 of B), T3 (90 kg ha-1 of N and 0 kg ha-1 of B) and T4 (90 kg ha-1 of N and 4 kg ha-1 of B). The results showed that there was a positive interaction between nitrogen and boron when applied together, providing increases in productivity and greater uniformity in beetroots.

Propagation of "coquinho-azedo" (Butia capitata) is limited due to dormancy and high incidence of fungi in its seeds. The aim of this study was to evaluate the effect of treating "coquinho-azedo" seeds with different concentrations of bactericide and/or fungicide on the incidence of fungi and on the germination of seeds. Thus, B. capitata seeds were immersed in four doses of the bactericide kasugamycin (0, 1.5, 3.0 and 4.5 mL/L) and/or in four concentrations of the fungicide carbendazim+ thiram (0, 2.92, 5.84 e 8.75 mL/ Kg), totaling 16 treatments. After the treatments, the operculum was removed from the seeds, which were placed on trays containing autoclaved sand, covered with transparent plastic film and kept in the nursery. In the germination test, treatments were distributed in randomized block design, factorial arrangement Keywords: Carbendazim, thiram, "coquinho-azedo", fungus, incidence. ABSTRACTof 4x4 (bactericidal doses x fungicide doses), with four replicates of 50 seeds per plot. For the test of seed health quality, the Blotter test was employed in completely randomized design, using 20 replicates and 10 seeds. Health quality and germination were evaluated at 15 and 40 days after the treatment of seeds, respectively. There was no interaction between the bactericide and the fungicide on germination and control of fungi associated with seeds. However, there was an effect of fungicide concentrations on the evaluated parameters. We observed a negative correlation between the concentrations of the fungicide carbendazim + thiram and fungal incidence, and a positive correlation between the fungicide concentrations and seed germination. Therefore, fungicide treatment reduces the fungal incidence and provides better germination of B. capitata seeds.

Modified atmosphere packaging (MAP) was evaluated for respiration rate, color, total phenolic content (TPC), antioxidant activity DPPH, flavonoids and pigments of fresh-cut Tropic Beauty peach. Modified atmospheres (21% O2 [Control], 5% CO2 [MAP1], 8% CO2 [MAP2] and 0% O2 [MAP3]) were evaluated for storing fresh-cut peaches for up to 10 days in temperatures of 5ºC. MAP significantly (p<0.05) affected the proprieties investigated as compared to control. Peaches with MAP3 have higher respiration(p<0.05) respiration rate than the peaches with the other treatments. Fresh-cut peaches in MAP2 showed more stable (p<0.05) carotenoid and anthocyanin contents, better attributes in the bioactive compounds. MAP1 and MAP2 exhibited better antioxidant proprieties at low storage temperature (5ºC) for up to 10 days storage and similar result was verified by principal component analysis used where modified atmosphere was observed as major factor.

The propagation of Caryocar brasiliense (pequizeiro) is still little known. This study aimed to evaluate different osmotic conditions with polyethylene glycol (PEG) in the imbibition process and in the germination of pequi seeds, in addition to verifying the electrical conductivity to evaluate the viability of these seeds. The experiment was conducted with freshly dispersed pyrenes and with pyrenes stored for 90 days. The electrical conductivity of the aqueous solution was measured every six hours for up to 48 hours, using five replications with 20 seeds. The extracted seeds were placed in PEG solutions with osmotic potentials: 0.0; −1.0; −2.0; −3.0; −4.0 MPa, monitored at intervals of 12 hours to 60 hours, plus additional treatment with dry seeds without any type of imbibition. The design was completely randomized with four replications of 25 seeds for germination and four replications of ten seeds for monitoring water content during imbibition. Germination percentage, germination speed index (GSI), percentage of dead and live seeds at 40 days were evaluated. In seeds with longer storage time, the electrical conductivity was higher. Treatments that were not submitted to PEG showed higher GSI, lower mortality percentage and higher germination percentage with 40% and 37%, respectively. The electrical conductivity test was adequate.
