Impact of Auxins on Vegetative Propagation through Stem Cuttings of Couroupita guianensis Aubl.: A Conservation Approach

Table 1

The effect of auxins on shoot bud induction in stem cuttings of C. guianensis after 60 days of treatment under greenhouse condition.

Note: stem cuttings with at least one shoot bud were considered for calculating percentage of shoot bud induction; SE: standard error; level of significance . All values are an average of 10 replicates. The mean values represented in corresponding column followed by the same alphabets are not significantly different. Here “a” represents/considered as the lowest value and “g” as highest value.
