【 摘 要 】
An experiment was conducted to assess the effect of pre-sowing seed treatment with triacontanol (TRIA) in canola ( Brassica napus L.) cultivar (RBN-3060) under saline stress. Canola seeds were soaked in three levels of TRIA (0, 0.5, and 1 mg L −1 ) for 12 hours. Three levels of salt stress (0, 100, and 150 mM NaCl) in full strength Hoagland's nutrient solution were applied to 56-days-old plants. Salt stress caused a significant reduction in growth, gas exchange, photochemical quenching ( qP ), and shoot and root K + contents, while increased leaf glycine betaine, free proline, and shoot Na + contents. Pre-sowing seed treatment with TRIA increased shoot fresh weight, number of seeds per plant, photosynthetic rate, transpiration rate, ratio of chlorophyll a/b , qP, electron transport rate, shoot and root K + contents, and free proline and glycine betaine contents of canola plants at various TRIA levels under nonsaline or saline conditions.
