TECHNIQUE FOR RAPID MULTIPLICATION OF GUAVA (PSIDIUM GUAJAVA L.)

Wedge method of grafting was tried in guava (Psidium guajava L.) cultivars Allahabad Safeda and Sardar under greenhouse (GH) as well as in open field conditions (OFC) for 3 consecutive years (2003-2005). The grafting operation performed in greenhouse gave significantly (P=0.05) higher success of grafts (64.56-94.33%) as compared to open field conditions (51.30-78.63%) in both the cultivars.
However, maximum success of grafts was obtained in greenhouse (88.63-94.33%) as well as in open field conditions (66.6-78.63%) when grafting was carried out during November to February in both cultivars.
Grafting under greenhouse significantly reduced the time taken (11-13 days) for sprouting than, those grafted in open field conditions.
Interaction effect of variety × greenhouse × month, variety × open field conditions × months and variety × factors (GH/OFC) × months had significant effect on success of grafts and earliness in grafts sprouting when grafting was performed in winter months.
The temperature range of 20°C to 26°C and RH 70 to 80 per cent were found most conductive for maximum (>70%) success.
