Abstract/ Executive Summary:

An attempt was made to develop a nursery procedure of Calamus guruba Buch-Ham. (Jali bet), C. tenuis Roxb. (Bandhari bet) and C. latifolius Roxb. (Korak bet) involving seed collection, pre-sowing seed treatment, media preparation, seed germination and seedling care. The plant percents obtained in C. guruba, C. tenuis and C. latifolius were 56, 58 and 62 respectively showing a good prospect for artificial regeneration of canes.

Location: Minor Forest Products nursery, Bangladesh Forest Research Institute, Chittagong

Start Date: 31-03-1983

End Date: 31-01-1985

Program Area: Conservation and Biodiversity

Commodity: Cane

Objectives:

a) To develop nursery procedure of three cane species like Calamus guruba, C. tenuis and C. latifolius.

Methodology:

Ripe fruits of C. guruba were collected from the natural stands of Chittagong in the last week of April. The ripe fruits of C. tenuis and C. latifolius were collected from Chittagong Hill Tracts in the second week of May and first week of June respectively. The fruits were opened by hand to separate the scaly layers. They were then soaked for 24 hours in a can filled with water to induce the fleshy layer of the fruit to ferment. The seeds were then separated from the fleshy layers. The clean seeds were allowed to settle at the bottom of the can and the fruit coverings to float over the settled seeds. The extracted clean seeds were then put in a basket and stored under room condition. The seeds were kept wet by watering until sowing. A seed-bed, 6.0 x 1.2 m, was prepared east to west in the nursery. The soil of the bed was worked to a depth of 30 cm. Then 18 kg of decomposed cow dung and 9 kg of compost were thoroughly mixed with the soil. Seeds were sown in the bed 5 cm apart in case of C. tenuis and 10 cm apart in case of C. guruba by dibbling each one just below the soil surface. Seeds of C. latifolius were sown directly in the polyethylene bags of 13 x 8 cm dimension. The bags were filled up with soil mixed with decomposed cow dung at the proportion of 3:1 by volume. Seed-bed and sown polyethylene pots were shaded by mats made up of locally available thatch grass. Watering was done whenever necessary using water sprinkler so as not to disturb the soil and seeds. When the seedlings of C. guruba and C. tenuis were of 2-3 leave stages (about 3 months old), they were transferred to polyethylene bags of 29 x 15 cm size. Each seedling was planted up to root-collar region. Watering was done immediately after pricking out so as not to allow the seedling to desiccate. The potted seedlings were kept under full shade for one week and then were exposed partially to the sun. Only the seedlings of C. latiifolius were repotted in the polyethylene bags of 20 x 15 cm. Repotting was done after 9 months of first germination.

Achievement/Findings:

The nursery procedure adapted has an important bearing in obtaining good levels of success in respect of germination of seeds and survival of seedlings. Regular watering and shading of seed-beds against direct sunlight may be considered as essential practices to obtain higher germination percentage of seeds. The mortality of seedlings, though not so high, may be further lowered by careful nursery operations particularly at the time of weeding and pricking out of seedlings so as to disturb neither the root system nor the portion of the tender seedlings. The plant percent obtained in all the three species may be considered promising enough to under-take large scale plantation of these cane species in young plantations of timber species and also in the village groves of the country. Further research to shorten the time required for starting germination and the period of germination is, of course, needed to improve the overall nursery technique of canes.
