Number of tubes for each concentration was five, i.e., ten for each concentration studied

Seeds showing below eight shoots were not considered

Average of number of shoots per tube was calculated and mentioned in above table

Number of shoots: Number of shoots = (A1 + A2 + A3… + A10)^b = X; Number of tubes = B; Average of shoots = X ÷ B

BAP 6-Benzyl amino purine, KIN kinetin, 2,4-D 2,4-Dichlorophenoxy acetic acid, NAA 1-Naphthaleneacetic acid

^aDetermination of shoots = Number of replicates for each concentration was two

^bA1–A10 is number of test tubes
