Effect of Rootstock and Grafting Methods on the Graft Success in Mandarin

Pomology Division, Horticulture Research Centre, BARI, Gazipur

Abstract/ Executive Summary:

An experiment was conducted at the Nursery of Pomology Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur from February 2010 to August 2010. Three grafting methods (Cleft, veneer and side grafting) and four rootstocks (Cleopetra mandarin, Rough lemon, Calamonsi and Rangpur lime) were used in this experiment. Scions were collected from the plant of BARI Komala-1. Higher percentage of grafting success was recorded in Cleft and Veneer method (92.40% and 89.3%, respectively) on Rangpur lime which was at par with Cleft and Veneer method on Rough lemon (90.50 and 85.2%, respectively). Cleft followed by Veneer method showed higher survivability when grafted on Rangpur lime (89.80% and 83.20%, respectively) as well as on Rough lemon (87.40% and 85.10%, respectively) at 180 DAG.

Keywords: Mandarin, Rootstock, Grafting method, Survivability, Plant growth

Location: Nursery of Pomology Division, Horticulture Research Centre, BARI, Gazipur

Start Date: 00-02-2010

End Date: 00-08-2010

Program Area: Variety and Species

Commodity: Orange

Objectives:

To study the effect of grafting method and rootstock in success, survivalist and growth of mandarin grafts
To determine the suitable rootstock for vegetative propagation of mandarin.
To standardized the suitable rootstock as well as effective grafting method for mandarin cultivation in Bangladesh.

Methodology:

The experiment was conducted at the Nursery of Pomology Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur from February 2010 to August 2010. For the experiment, scions were collected from the plant of BARI Komala-1. Three grafting methods (Cleft, veneer and side grafting) and four rootstocks (Cleopetra mandarin, Rough lemon, Calamonsi and Rangpur lime) were used in this experiment. The grafting operations were done in 2 February 2010. Twenty grafts were used in each treatment combination in each replication. This experiment was laid out in factorial Randomized Complete Block Design with three replications. The grafts were watered regularly. Intercultural operations like weeding, pest and disease control etc. were done as and when necessary. Days to bud break were considered when 50% new leaf emergence was occurred. Data on days to bud break, success after 30, 60 and 90 days of grafting; length and diameter of shoot, number of shoot and leaves per sapling after 90, 180, 270 and 360 days of grafting from each experimental unit were recorded and analyzed statistically using MSTATC soft ware.
