Chitosan, which is a unique amino polysaccharide along with renewable resources, has attained great awareness because of its special structure, properties and its inexpensive plentiful sources. The specific properties of chitosan such as biocompatibility, biodegradability, bioactivity, low immunogenicity and multi-functionality increase its potenti...

Many researches have reported plant growth promotion activity of irradiated chitosan and sodium alginate (Na-alginate) individually. However, there is no study on the combined effect of irradiated chitosan and Na-alginate on plant growth and quality of the produces. In this study, individual effects of gamma-radiation-treated chitosan and Na-alginate were compared with the mixed solution of irradiated chitosan and Na-alginate by the means of growth and taste of pineapple. Gamma-irradiated Na-alginate treatment with an interval of 30 days showed maximum plant growth while the best pineapple fruit growth was found for the Na-alginate treatment with an interval of 15 days. On the other hand, gamma-irradiated chitosan treatment showed better fruit quality with respect to taste and flavor. However, in terms of both growth and quality, the mixed solution (90:10 irradiated Na-aliginate:chitosan) was found to be the best. A significant increase of pineapple size, sweetness, aroma, and flavor was recorded in case of the mixed treatment with 30 days of interval.
