Abstract:
Pepper plants belong to the family Piperaceae. There are several types of piper species
such as Piper aduncum, P. be tie, P. longum, P. nigrum, P. futokudsura, P. kudsura etc.
Piper species have a tropical distribution, and are most commonly found in the
understory of lowland tropical rainforests. The objective of this research was to study of
the vegetative propagation of exotic pepper. Three different potting media of sand, coir
dust, sand: coir dust (1:1) was used for the experiment. The medium were sterilized by
using mini autoclave and filled in plastic trays. Piper vines were cut separately as top
cuttings and semi hard wood cuttings. 50% "of the cuttings were treated with IBA
hormone and balance 50% were not treated with IBA hormone. Cuttings planted in
plastic trays were covered with transparent polythene for four weeks. The Experiment
was conducted according to completely randomized design with six replicates. Data
were analyzed using SAS computer package. Number of roots and root volume were
affected significantly (p<0.05) by all the experimental factors which include potting
medium, cutting type and hormones. Maximum number of roots was recorded in semi
hard wood stem cuttings planted in 1:1 sand: coir dust medium treated with IBA
hormone. Number of shoots was significantly affected (p<0.05) by only in potting
medium and not affected significantly (p>0.05) in cutting type and hormone treatment.
