Control efficacy against Geotrichum citri-aurantii and effects on postharvest storage quality of Ponkan fruit by combining thyme oil with sodium carbonate
百里香精油与碳酸钠结合对桠柑酸腐病的防治效果及品质的影响

Control efficacy and effects on postharvest storage quality of thyme oil in combination with different concentrations of sodium carbonate (SB) against postharvest disease caused by Geotrichum citri-aurantii in Ponkan fruit were investigated. The results indicated that combining thyme oil with SB provided a more effective control on G. citri-aurantii than applying the thyme oil or SB alone. One thousand and six hundred μL·L~(-1) thyme oil combined with 0.5% SB showed the best effect, and growth of G. citri-aurantii was completely inhibited in the wound of Ponkan fruit. Four hundred μL·L~(-1) thyme oil combined with 1% SB decreased 60% sour rot disease, and had no obvious effects on contents of titratable acid, total soluble solids, VC and fruit firmness after 30 d.
