Technique for Rapid Multiplication of Guava (Psidium Guajava L.)

Abstract

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.

Standardization of Optimum Season for Softwood Grafting in Guava (Psidium guajava L.) cv. Sardar

“…Guava (Psidium guajava L.) is one of the most promising fruit crops of India and is considered as one of the nutrionally valuable and remunerative crops (Singh et al, 2007). Guava fruits are used for both, fresh consumption and processing.…”

Study the Survivability of Grafts in Different Varieties of Guava (Psidium guajava L.) by Softwood Grafting under Different Growing Conditions

“…Whereas, the lowest graft survival (47.82 %, 44.66 % and 35.08 %) was registered in Lalit at 30, 60 and 90 days respectively after softwood grafting. Singh et al, (2007) also reported that significantly higher success of grafts (64.56-94.33%) in green house compared to open field condition (51.30-78.63%) in Sardar and Allahabad Safed (Fig. 1, 2 and 3).…”

Effect of Time and Environment on Wedge Grafting of Guava (Psidium guajava L.) cv. Sardar

“…Maximum plant height (cm) and length of scion shoot (cm) (64.95 and 39.05) respectively performed in March. Singh and Sengupta (1996) also recorded maximum sprout length in the plants grafted during March. The higher plant and scion length recorded in plants grafted in March and April in the present study may be because of the fact that grafted plant faced long periods of rainy season.…”
