Abstract

he purpose of the study was to evaluate the effect of salinity levels of irrigation water on physiology and growth of banana cultivars during the vegetative stage. The experiment was carried out following a completely randomized design in split plots, with four levels of salinity in irrigation water (0.5, 2.0, 3.0 and 4.0 dS m-1) and fourbanana cultivars (Pacovan, Prata Ana, BRS Platina and Princesa) with three repetitions. Stomatal conductance, transpiration, relative water content, leaf water potential and proline concentration were evaluated at 150 days after transplanting (DAT), besides plant height, stem diameter and leaf area. All variables showed sensitivity to the increase of salinity level of irrigation water. The results of soil water extraction, relative water content in leaf (RWC), leaf water potential and proline content differed (p ? 0.05) among the cultivars. Prata Ana and BRS Platina cultivars were the ones with lowest sensitivity, while Pacovan and BRS Princesa cultivars showed larger variation of soil water extraction and RWC with the increase in irrigation water salinity (electrical conductivity), being considered the ones of highest sensitivity to salinity in this study. Banana crop growth as a consequence of physiological effects was inhibited by the increase in water salinity, mainly in ?BRS Princesa? cultivar

灌溉水盐度对香蕉品种生理和营养行为的影响

本研究旨在探讨不同盐度灌溉水对香蕉营养期生理和生长的影响。试验采用完全随机分块设计，灌溉水盐度设置为4个水平(0.5、2.0、3.0和4.0 dS m-1)， 4个香蕉品种(Pacovan、Prata Ana、BRS Platina和Princesa)，重复3次。在移栽后150 d，除株高、茎粗和叶面积外，测定气孔导度、蒸腾、相对含水量、叶片水势和脯氨酸浓度。各变量对灌溉水含盐量的增加均表现出敏感性。土壤水分提取、叶片相对含水量(RWC)、叶片水势和脯氨酸含量差异显著(p ?0.05)。Prata Ana和BRS Platina是敏感性最低的品种，而Pacovan和BRS Princesa品种的土壤水分提取率和RWC随灌溉水盐度(电导率)的增加变化较大，被认为是本研究中对盐度敏感性最高的品种。由于生理效应的影响，香蕉作物的生长受到水盐度升高的抑制，主要是在公主香蕉。品种
