Propensity of endemic Exacum spp. (Binara) as an Ornamental Plant: A Case Study among Agricultural undergraduates, University of Ruhuna, Sri Lanka

Abstract

Introduction of new plants is critical to the survival and profitability of the floricultural industries. These provide a marketing edge and can offer real benefits to fulfill special floriculture needs. Present survey was conducted to observe the potential of endemic Exacum spp. (Binara) as an ornamental plant among younger generation. The sample was selected from undergraduate students (n=125), Faculty of Agriculture, University of Ruhuna, Sri Lanka. Semi-structured interviews were carried out among the undergraduates representing all districts of Sri Lanka using a pre-tested questionnaire and showing a specimen of Binara plant. Group discussions were conducted with randomly selected students; 5 students/ group. Data were analyzed descriptively and presented with appropriate descriptive tools. The survey revealed that lack of awareness about Binara plant among the university students (66%) in most of the Districts of Sri Lanka. The results showed those respondents around 78% like to natural colour (blue-purple), actual flower size (50%),natural texture of flower petal (60%) and the height of the plant (70%) of the Binara flower. The respondents of 36% have not clear idea about vase-life of Binara flower. The respondents were more like to use Binara plant as potted plant (60%) than cut flower (40%). When considering the propagation of Binara, 58% respondents accept with propagation by seeds (58%) rather than asexual propagation (42%). However seed propagation of Exacum is hard in home level as its seeds are very small (110-140μm). Among vegetative propagation techniques, 68% respondents suggested to develop cutting than layering (42%). Most of the respondents liked to use Binara plant as an ornamental plant and it was shown that the ornamental value of Binara flower will help to develop the floriculture industry.
