Assessing the regression of characters in shoot induction Of potatoes )Agrian cultivar)

چکیده مقاله

To evaluate the effect of six combined hormones and vitamins as treatments on some of traits in potatoes cultivar (Agria), an experiment was conducted in 2014-2015 in a randomized complete block design with three replications in laboratory condition. Linear and quadratic regression analysis showed that between the two evaluated traits (y = main shoot length, x = number of secondary shoot) there was a significant relationship as follows: y=75/278-2/087x and y=76/546-2/699x+0/061x2. The above equation shows that by increasing the number of secondary shoot, main shoot length decreases. Linear and third degree regression analysis showed that between the two evaluated traits (y = the maximum of secondary shoot length, x = number of secondary shoot) there was a significant relationship as follows
