Abstract:
The present investigation was carried out to find out the graft compatibility of Crossandra infundibuliformis with different rootstocks and to confirm the suitability of the type of grafting method. The experiment consisted of 6 different rootstocks viz., Adathoda vasica, Delhi Crossandra, Crossandra infundibuliformis, Barleria cristata Ecbolium viride and Barleria prionitis along with 3 grafting methods i.e. wedge, splice, and saddle grafting, it was laid out in factorial randomized block design (FRBD) with 3 replications. The results indicated earlier days taken for sprouting in T₁G₁ (wedge grafting in Adhatoda) – 13.61 days, while an increased number of sprouts per graft (4.30), increased graft success percentage (82.22), graft survival percentage (61.72), in T2G1 (Delhi Crossandra + wedge grafting). Concerning the sprout length and graft height recorded at 30, 60, 90, and 120 days after grafting, increased sprout length and graft height was recorded in T₁G₂ (Adathoda + wedge grafting) at 30 and 60 DAG, later during 90 and 120 DAG, T₃G₁ (Crossandra seedling+ wedge grafting) registered increased values. The lowest values were observed in Barleria cristata + wedge grafting combination.
