When the yellowing temperature was higher ( 38 42 ℃) whether the rate of temperature increase for leaf drying was quick or slow the inherent quality of the cured leaves would decrease to certain degrees .

在高温（38～42℃） 变 黄条件下，无论定色升温速度快慢，烤后 烟叶的内在质量都有不同程度下降。

The results showed that in the pot experiment the yellowing degree of rice leaves of bacterium treatment was remarkably slighter than that of control . The PM residues in rice of the bacterium treatment reduced by 82.2-100 % .

在盆栽试验中，处理的 各 叶片 变 黄程度比对照均要轻，统计差异显著，稻米与稻壳中甲基对硫磷处理比对照下降了82.2－100%。

The vertical temperature and humidity difference ( 1 ℃~ 2 ℃) decreased effectively which made the whole oven of tobacco leaves yellowing and drying under the generally same temperature and humidity condition and increased the whole cured tobacco leaves quality .

能有效降低烤房上、下层温湿差（温湿差1℃～2℃），使整炉烟叶在基本一致的温湿度条件下 变 黄干燥，提高了 烟叶的整体质量。

The results showed that yellowing temperature and humidity had the most significant effect on the material transition and the inherent quality of the cured leaves and the effect of humidity was more significant .

结果表明， 变 黄 阶段的温度和湿度对 烟叶内在物质的转化和质量形成影响最大，其中湿度的影响更大。

To reduce the yellowing of temperature and humidity difference appropriately has a certain influence on the yield and quality of upper leaves .

适当降低 变 黄 期温湿差对上部 烟叶产质量有着一定的影响。

The results showed that : 1 ) the change of protein content mostly occurred during the early stages ( wilting and yellowing stages ) of air-curing particularly apparent in upper and middle leaves ;

结果表明①烟叶中蛋白质含量的变化主要发生在晾制前期，中湿处理的 烟叶蛋白质含量下降趋势较为明显，在 变 黄期 仍有下降趋势。

Effect of Different Temperature of the Yellowing Stage on Contents of Main Carbohydrate of Tobacco Leaves

不同 变 黄温度对 烟叶主要糖类物质 的影响

On the basis above the coordinated technology indexes of the rate of yellowing and that of loss water at upper leaves were determinated and it was emphasized that improving yellowing degree and proper increasing wet bulb temperature was the key of the flue curing at upper leaves .

在此基础上，研究 确立了上部 烟叶 变 黄速度和失水速度相 适应的技术指标，强调提高烟叶变黄程度和适当增加湿球温度是烤好上部烟的关键。

Under the conditions of soil culture the main toxic symptoms of eggplant were yellowing of leaves accompanied by brown patch defoliation stunt and even death of plant .

土培条件下，茄子铅毒害 的主要症状为： 叶片失绿 变 黄、伴有 黄褐斑、并逐渐脱落；植株矮小，甚至死亡。
