Resumo
No Brasil, particularmente no Estado de São Paulo, o cultivo de berinjela se desenvolveu muito, porém sua maior limitação é o controle do teor de água do solo. Pesquisas recentes destacam as propriedades medicinais da berinjela, mostrando que nos últimos anos sua procura tem aumentado significativamente, principalmente para o uso de controle do colesterol e enfermidades no aparelho digestivo; além de apresentarem em sua composição nutricional, algumas vitaminas e minerais essenciais como cálcio, fósforo, ferro e potássio. A água é o fator ambiental mais importante para o desenvolvimento das plantas, pois todo e qualquer processo relacionado com a água é fortemente influenciado pelas condições do ambiente, do solo e do ar atmosférico. Nesse sentido, no presente trabalho, conduziu-se plantas de um híbrido de berinjela (Solanum melongena L.), denominados comercialmente “Embu” com o objetivo de se estudar possíveis impactos na produção, decorrentes de uma deficiência hídrica (DH) induzida sobre a cultura. As plantas foram conduzidas em casa de vegetação da Faculdade de Ciências Agronômicas da UNESP - Botucatu-SP, no Dep. de Produção Vegetal, setor de Horticultura. O delineamento experimental foi inteiramente casualizado (DIC), em esquema fatorial 3 x 4, ou seja, três níveis de água no solo e quatro épocas de coleta, com 16 repetições para cada tratamento. As repetições foram separadas em quatro parcelas com quatro vasos por parcela. O primeiro tratamento foi considerado Controle onde as plantas foram irrigadas ao atingir o valor 2 de potencial mínimo de água do solo de -10 kPa. Os demais tratamentos simularam DH Leve (-20 kPa) e Moderada (-30 kPa), respectivamente, também irrigadas ao atingir os valores de potencial mínimo de água do solo, sendo todos os tratamentos monitorados...
In Brazil, particularly in the State of São Paulo, the cultivation of eggplant developed very much, but its great limitation is the control of amount of water of soil. Recent studies feature the medical properties of eggplant, showing that, in the last years, its search has been increased significantly, mainly to the use of control of the cholesterol and illness into digestive system; besides of show in its nutritional composition, some essential vitamins and minerals such as calcium, phosphore, ferro and potassium. Water is the most important environmental factor to the developing of plants, because every and any process related with water é strongly influenced for the environmental conditions, soil, and atmospheric air. In this way, in present study, it had been lead plants of a hybrid of eggplant (Solanum melongena L.), named commercially “Embu” with the aim of studying possible impacts on production, elapsing 4 of a hydric deficiency induced on the culture. The plants were conducted in house of vegetation of Faculdade de Ciencias Agronomicas da UNESP- Botucatu-SP, in Department of Vegetal Production, sector of Horticulture. Experimental design was entirely randomized, in factorial design 3X4, that is, three levels of water in soil and four times of collect, with 16 repetitions for each treatment. Repetitions were apart in four portions with four pots for portion. First treatment was considered Control which the plants were irrigated up to hit the value of minimal potential of soil...
