Abstract:
Different mini-watermelon varieties of ‘Xiuya’and ‘Xiuli’ were used as materials，two mini-watermelon cultivars differing in salt tolerance were conducted to study the effect of different concentration of NaCl stress on the growth of mini-watermelon seedlings in hydroponically.The results showed that NaCl treatments below 50 mmol/L didn’t apparently influence the growth of ‘Xiuya’ seedlings，its growth was significantly inhibited above 75 mmol/L；with increasing NaCl concentration，the growth of ‘Xiuli’ seedlilngs was significantly reduced.With increasing NaCl concentration and prolonging stress time，salt injury index was clearly increased，and survival percent was dramatically decreased under NaCl stress above 75 mmol/L.The research revealed that NaCl stress significantly inhibited the growth of mini-watermelon seedlings，but the response of two cultivars to salinity was different，the range of growth reduction of ‘Xiuya’ seedlings was less，salt injury index was lower and survival percent was higher than ‘Xiuli’ under salinity，i.e.the acclimation of ‘Xiuya’ to salinity was better than ‘Xiuli’.
