Popis: | The present investigation was aimed to assess the effect of different concentrations of elicitors viz., salicylic acid (SA) and benzothiadiazole (BTH) on physiomorphological and biochemical parameters of Brassica juncea and B. napus cultivars. The field experiment was conducted during 2012-13 at Punjab Agricultural University, Ludhiana, India. Four different treatments of elicitors and a fungicide treatment were given to 10 week old plants up to four consecutive weeks. Content of total soluble protein, free amino acids, total sugars and reducing sugars ofleaves of both B. juncea and B. napus were evaluated after each spray. The content of total soluble protein increased, whereas the contents of free amino acids, total sugars and reducing sugars decreased in all the treatments after each spray. Among all the treatments, the combinations of elicitors, i.e., BTH (3 ppm) + SA (33 ppm) and BTH (7 ppm) + SA (17 ppm) exhibited maximum contents of total soluble protein, free amino acids, total sugars and reducing sugars than control in both the cultivars. These treatments were more pronounced in increasing plant height, internodal distance and number of pods per plant in both the cultivars. Our results suggest that the combinations of elicitors act synergistically to promote growth and metabolic activities in B. juncea and B. napus cultivars leading to the induction and regulation of disease resistance. |
