EFFECT OF DIFFERENT PROPAGATING STRUCTURES ON ROOTING OF HARDWOOD CUTTINGS OF GRAPE (VITIS VINIFERA L.) VARIETIES

Significant variations in shoot and root parameters were recorded in hardwood cuttings of grape varieties kept under different propagating structures including open condition. Among the various structures, medium cost greenhouse structure with humidifier and fans (S₂) was found to produce cuttings with a higher number (14.61) and length (14.51 cm) of roots, a higher percentage of rooting (92%) and a higher percentage of survival (96.68%), while high cost greenhouse structure with misting (S₁) produced a higher number of leaves and sprout length with early sprouting (19.52 days). With respect to varieties, Dilkush performed better for both shoot and root parameters compared to Bangalore Blue.
