Abstract:
The investigation provides a novel anti-sprouting agent for inhibiting growth of potato tubers (Solanum tuberosum L. cv. Fridor). The antisprouting of CIPC, geranyl acetate, geraniol, camphor, citral, linalool, l-carvone, d-carvone, d-citronellol and l-citronellol of essential oils were used. Subsequent experiment has also been established to study the effect of geraniol and citral at different concentrations (4, 6 and 8 mM) on eyes sprouted (%) into the tuber. Therefore, four storage experiments were carried out at El-Mansoura Horticultural Research Station, Egypt, during the two successive summer seasons of 2012 and 2013. Potato tubers treated with geraniol or citral emulsions and stored at ambient temperature showed the lowest significant values of sprouting and weight loss percentage in both seasons of the study. CIPC inhibited sprouting over 98.5%. Application of geraniol or citral resulted in the highest value of dry matter and had a significant effect on reducing sugars and total free amino acids, in both seasons. Tubers of control treatment were of the lowest significant peroxidase activity POD. All treatments, except for the control, gave the best quality processing of chips and French fries. In another experiment sprouting was completely inhibited at 6 or 8 mM concentrations in the end of storage period (120 DAS). The study suggests that using geraniol or citral emulsions (8 mM) and stored potato tuber at ambient temperature are safe, ecofriendly and economically viable.
