Table 3.

Profuse rooting in multiple shoots of indica rice cultivars cultured on MS culture medium with various concentrations of growth regulators

Name of cultivars	Number of days	Average number of rootsa	Growth regulator (IBA mg L−1)
PR-115	18	09.54 ± 0.48	1.0
PR-116	19	08.69 ± 0.68	1.0
Sambha mahsuri	18	13.63 ± 0.83	1.0
Erramallelu	19	10.44 ± 0.73	1.0

Number of replicates for each concentration was two

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

Shoots showing below 8 shoots were not considered

Average of number of roots per shoot in each tube was calculated and mentioned in above table

^aDetermination of roots = number of roots = (A1 + A2 + A3… + A10)^b = X; number of tubes = B; average of roots = X ÷ B

^bA1–A10 is number of test tubes
