RESULTS: The results showed that all investigated traits were significant under the treatment of seaweed extract compared with the control. The seaweed extract concentrations had a significant effect on all traits except soluble carbohydrates, but the time of consumption of seaweed extract on soluble carbohydrates, protein, peroxidase, ascorbate peroxidase, and superoxide dismutase enzymes was significant, while had no significant effect on the rest of the traits. According to the interaction effect of time and concentration of consumption of seaweed extract, the highest values of the biochemical characters were as follows: total phenol content: 168.30 mg CAE/g DW, flavonoid content: mg CE/g DW, catalase: 12.66 µmol APX min- 1 mg- 1 protein, superoxide dismutase: 231.4 µmol APX min- 1 mg- 1 protein, and ascorbate peroxidase: 39.53 µmol APX min- 1 mg- 1 protein.
CONCLUSIONS: Based on the results of this study, it seems that it is possible to use fertilizers containing A. nodosum seaweed extract with a concentration of 3 g/L in August to increase the tolerance of the pistachio cultivar \"Kaleh-Ghoochi\" to abiotic stresses.
结果:结果表明,与对照相比,在海藻提取物的处理下,所有研究的性状均显着。海藻提取物浓度对除可溶性碳水化合物外的所有性状都有显著影响,但是海藻提取物在可溶性碳水化合物上的消耗时间,蛋白质,过氧化物酶,抗坏血酸过氧化物酶,超氧化物歧化酶是显著的,而对其余性状无显著影响。根据海藻提取物消耗时间和浓度的交互作用,生化性状的最高值如下:总酚含量:168.30mgCAE/gDW,类黄酮含量:mgCE/gDW,过氧化氢酶:12.66μmolAPXmin-1mg-1蛋白,超氧化物歧化酶:231.4µmolAPXmin-1mg-1蛋白,和抗坏血酸过氧化物酶:39.53μmolAPXmin-1mg-1蛋白。
结论:根据本研究的结果,似乎有可能在8月份使用含有3g/L浓度的结节性海藻提取物的肥料,以增加开心果品种“Kaleh-Ghoochi”对非生物胁迫的耐受性。
