摘要

Abstract

The saline-alkaline sensitive type('YE988'),saline-alkaline intolerant type('S2102'),saline-alkaline tolerant type('Longkuiza No.4'),and strong saline-alkaline tolerant type('Chuyouzhizun 909S')were used as experimental materials.Four melatonin concentrations of 0(CK),1(K1),10(K2),and 100 μmol·L-1(K3)were set at 0.6%compound saline-alkaline concentration to explore the effects of different melatonin concen-trations on photosynthetic characteristics and yield of oil sunflower under compound saline-alkaline stress.The re-sults showed that compared with CK treatment,K1,K2,and K3 treatments could improve the photosynthetic char-acteristics of oil sunflower under saline-alkali stress,and the net photosynthetic rate at the flowering stage increased first and then decreased.'YE988','S2102','Longkuiza No.4',and'Chuyouzhizun 909S'reached the maxi-mum under K2 treatment,which were 49.38,39.47,38.64,and 43.16 μmol·m-2·g-1,respectively,which were 2.9%～53.9%higher than CK.The yield of K2 treatment reached 5700.77,5 855.45,6 005.65,and 6 171.96 kg·hm-2,respectively,which was 6.6%～22.3%higher than that of CK.In summary,melatonin can alleviate the adverse effects of saline-alkali stress on photosynthesis of oil sunflower and improve its saline-alkali tolerance.Under the conditions of this experiment,the 10 μmol·L-1 treatment had the best effect.
