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.

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 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.
