Chitosan also promoted growth of various crops such as cabbage (Brassica oleracea L.) Hirano 1988), soybean sprouts (Lee et al. 2005) and sweet basil (Kim et al. 2005).Chitogel, a derivative of chitosan, was found to improve vegetative growth of grapevine plantlets (Barka et al.2004). This study showed that the average O2
production by plantlets cultured on medium supplemented with 1.75 % chitogel increased 2-fold, whereas CO2
fixationincreased only 1.5-fold, indicating that chitogel had abeneficial effect on net photosynthesis in plantlets andconfirmed its positive effects on grapevine physiology. It has also been shown that chitosan promotes vegetative growth and enhances various processes in developingflower buds (Barka et al. 2004). N-acetyl chitosaccharides concentration was varied in growth media depending onthe chemo/ physiological conditions of the cells, which caused much higher root growth than in control production media. Chitosan treated orchid plants (Dendrobium Sen-sational ‘Purple’) had more flower shoots and yields tendedto be higher compared to the control plants (Chandrkra-chang et al. 2005).
