【 摘 要 】

The effect of irrigation withholding and bio-fertilizers on grain filling components, chlorophyll content and some fatty acids composition Gacomo cultivar of canola, was studied by  factorial experiment based on randomized complete block design with three replications in Agricultural Research Station of Ardabil in 2015-2016. Experimental factors were included irrigation in three levels, full irrigation or control, irrigation withholding at 50% of flowering and pod formation stage, irrigation withholding at 50% of grain formation stage and application of bio fertilizers in four levels, no inoclulation, inoclulation with Nitrobacter, Psedomonas and Azospirillum. Results showed that water limitation decreased yield, number of grain per pod, number of pod per plant, rate and grain filling period, oleic acid, linolenic acid and photosynthetic pigment.­ Whereas erucic acid and palmetic acid content were increased. Means comparison showed that the highest of yield (1.62 ton.ha-1), number of grain per pod (30.66), number of pod per plant (76), grain filling period (54.42 days), chlorophyll a (23.33 mg.g-1 FW), total chlorophyll (29.83 mg.g-1 FW), oleic acid (69.24%) and linolenic acid (11.54%) were obtained in inoculation with Azospirillum and full irrigation. The highest content of erucic acid (2.89 %) and palmetic acid (4.56 %) were observed at no inoculation and irrigation withholding in grain formation stage. Also irrigation withholding in flowering and pod formation stage and grain formation stage decreased 46% and 40.4% respectively from grain yield and application of Azospirillum, Psedomonas and Nitrobacter increased grain yield 53.7%, 9.2% and 44.4% respectively in flowering and pod formation stage and 65.5%, 31% and 17.2% respectively in grain formation stage. According to the results, it seems that Azospirillum application can be suggested as the best treatment for profitable canolaproduction under full irrigation and water limitation condition.
