ảnh hưởng của Retain - AVG ( Aminnoethoxyvinylglycine) đến thời hạn bảo quản sau thu hoạch chuối tiêu (Musa AAA Cavendish) | TẠP CHÍ KHOA HỌC VÂ CÔNG NGHỆ Tập 47 số 1 2009 EFFECTS OF RETAIN - AVG AMINOETHOXYVINYLGLYCINE ON THE STORAGE TIME OF BANANA MUSA CAVENDISH AAA AFTER HARVEST NGUYEN VAN TOAN LE VAN HOANG LE VAN TAN LE THI LIEN THANH CHU DOAN THANH TRUONG MINH HANH ABSTRACT In this study we investigated the effects of Retain - AVG at different concentrations g l g l g l g l and 0 g l in combination with low temperature preservation on banana storage time. The results showed that at storage temperature of 13 c the most suitable concentration of Retain - AVG was g l resulting in a storage time of days compared to 24 days without the use of Retain - AVG. The respiration intensity firmness damage rate total sugar content and total acid content of banana during storage under different conditions have been determined. Results obtained for the best Retain-AVG concentration g 1 13 c 24 days were as follows Respiration intensity ml COj with Retain - AVG compared to ml 1 without Retain - AVG . Fruit firmness 2 with Retain - AVG compared to 2 without Retain - AVG Total sugar content with Retain - AVG compared to without Retain -AVG . Total acid content with Retain - AVG compared to without Retain -AVG Damage rate with Retain - AVG compared to without Retain - AVG . Keywords Retain - AVG Banana Ethylene and Ripening. 1. INTRODUCTION Banana is one kind of the fruit trees grown widely and for a long time in Viet Nam as well as in the world. Among different types of bananas Musa Cavendish AAA is the most popular because of its nutrient quality appearance as well as high export value. The aim of this study was to find out how to preserve fresh bananas in order to prolong the post-harvest ripening time. One of the most significant solutions currently applied is the use of ethylene combined with low temperature storage in which Retain - AVG is considered as the subject of the .
