Treatments was replicated four times , the means separation were preformed via least significant difference procedures at p ≤ 0.05 .

The result indecat that Com Sol , Gibberellic acid and Stress relief significantly increased shoot leangh , leaves area , leaves number and shoot number, the binary interaction between the factors (C2G2 , C2S2 , G2S2) significantly increased growth characteristic, triple interaction between the factors (C2G2S2) significantly increased growth characteristic and gave the highest results .
