Study on the Growth and Baking Characteristics of the New Flue-cured Tobacco Variety Luoyan 1
To clarify the field growth and roasting characteristics of a new flue-cured tobacco strain,Luoyan 1 was compared with Zhongyan100 to analyze its field growth performance,as well as its discoloration,water loss,chlorophyll degradation and polyphenol oxidase activity changes in tobacco leaves in the dark box and roasting experiment.The results showed that Luoyan 1 plant had high height,leaf surface shrank and leaf tip drooped obviously.Compared with Zhongyan 100,the plant height and the number of leaves increased obviously.At 60 days after transplanting,Luoyan 1 grew rapidly in height,and the leaves grew first and then widened,and plant development degree basically stopped increasing.In terms of baking characteristics,compared with Zhongyan 100,Luoyan 1 to-bacco leaf browning rate and chlorophyll degradation rate were slower,water loss rate was faster,yellow characteristics and water loss balance was slightly poor,tobacco leaf color fixation was not easy.To sum up,in order to highlight the tobacco leaf quality of Luoyan 1,appropriate adjustments can be made to the baking process:high temperature yellowing at the early stage of yellowing,appropriate reduction of dry and wet bulb temperature difference,reduce water loss of tobacco leaf,adjust the coordination between tobacco leaf yellowing and water loss,appropriately raise the dry and wet bulb temperature difference at the later stage of yellowing and early stage of color setting,increase moisture discharge,and prevent tobacco leaf from becoming hard and yellow.
