Graft compatibility among the Asian and Algarobia Prosopis species

Abstract

Graft inter-relationships have been studied among four Prosopis species, viz. the Asian P cineraria and P juliflora, P Alba and P nigra of section Algarobia. Reciprocal stock-scion combinations were attempted by bud grafting using each species as stock as well as scion. The autografts in all the four species were successful. In P cineraria, P juliflora, P Alba and P nigra respectively 88.9, 88.9, 72.2 and 11.1 per cent successful grafts were obtained. The graft combinations between the species within section Algarobia were also successful. Patch budding P nigra scion on P juliflora rootstock gave 83.3 % successful grafts. Thus true-to-type plantations of these species could be raised by patch budding on their own roots. The combinations of P cineraria with any of the other three species of section Algarobia were incompatible.
