Abstract:
Effects of low temperature stress(15 ℃/5 ℃，day/night，for 7 d) on growth and physiological indexes of four species of watermelon rootstocks seedlings were studied.The results showed that，plant height，stem diameter，shoot fresh weight，root fresh weight,root activity,soluble sugar content,proline (Pro) content，superoxide dismutase (SOD) activity，peroxidase (POD)activity of ‘Huangjindadang’ seedlings were the highest after low temperature，but malondialdehyde (MDA) content was opposite.It was visible that ‘Huangjindadang’ was worthy of popularization and application in the low temperature production of watermelon.
