Title

Dynamics of Environmental Humidity and Water Content in Tobacco Leaf and Metabolism of Starch During Curing

Gong Chang-rong 中国农业科学(英文版) 2003

Other claims from this paper (10)

Intervention effect During early yellowing at low humidity, starch degradation and the decrease of water content in tobacco leaf were the most rapid.
Intervention effect Water loss was lowest under high humidity.
Intervention effect Starch residue in cured leaf differed among high-humidity yellowing, low-humidity yellowing and CK treatments in the stated order.
Intervention effect The duration of starch degradation under low humidity was longer than in CK.
Observation When leaf water content fell to around 50%, starch degradation became slow and starch content was stable.
Observation Starch degradation and the decrease of leaf water content were not synchronous.
Intervention effect Starch in tobacco leaf degraded more rapidly during yellowing when humidity was decreased at a high speed, but degradation stopped earlier at the late stage.
Intervention effect Starch degradation was quicker and higher under high environmental humidity.
Observation When humidity decreased to 70%, starch content was stable.
Observation Amylase activity stayed at a high level when environmental humidity was below 70%.

Dynamics of Environmental Humidity and Water Content in Tobacco Leaf and Metabolism of Starch During Curing

GONGChang-rong; CHENJiang-hua 中国农业科学：英文版 2003

Other claims from this paper (14)

Intervention effect Low humidity during early yellowing gave the fastest starch degradation.
Intervention effect Low humidity during early yellowing gave the fastest decrease in leaf water content.
Intervention effect Water loss was highest at low humidity and lowest at high humidity.
Intervention effect Starch degradation lasted longer under low humidity than CK.
Observation Cured leaf starch residue ranked high humidity above low humidity above CK.
Association Starch degradation slowed near 50% leaf water content.
Association Starch content stabilized near 50% leaf water content.
Observation Starch degradation and leaf water loss were asynchronous.
Intervention effect Rapid humidity decline caused faster starch degradation during yellowing.
Intervention effect Under rapid humidity decline, starch degradation stopped earlier at a late stage.
Intervention effect High environmental humidity gave quicker starch degradation.
Intervention effect High environmental humidity gave higher starch degradation.
Association Starch content stabilized when humidity fell to 70%.
Association Amylase activity remained high below 70% environmental humidity.
