变褐

Plant proteases are enzymes which solubilize plant proteins and browningis a chemical reaction resulting from high temperatures.

植物蛋白酶是一种能够溶解蛋白质的酶，褐变是植物组织在高温条件下的一种化学反应。

The results showed that 22.5μL/L of clove leaf oil had the best preservation effect on peach. After 35 days of stock, the sound fruit rate was 94%, 46.9% higher than compared group. The rotten index and the browning index were 94.1% and 85.2% lower than the control, respectivly, and the treatment could remarkablely reduce the respiration rate and ethylene release, and postponed ethylene release peak and respiration peak 5 and 10d, respectively in comparison with CK, it also delayed the drop of firmness and contents of titrable acids of the peach. When stored for 35d, firmness of control group and 22.5μL/L of clove leaf oil were decreased 60% and 34% compared with initial storage, and the activities of SOD, CAT and POD were enhanced, but the contents of SSC had no obvious difference with control.

结果表明，与对照相比，22.5μL/L丁香叶油处理对桃果实的防腐保鲜效果最好，贮藏35d时好果率为94%，比对照提高了46.9%，腐烂指数和褐变指数分别比对照低94.1%和85.2%；丁香叶油处理可以有效降低桃果实的呼吸强度和乙烯释放量，呼吸强度高峰和乙烯释放量高峰分别推迟5和10d，延缓了果实硬度和可滴定酸含量下降的速度；贮藏35d时对照和22.5μL/L丁香叶油处理果实硬度分别比贮藏初期降低了60%和34%；丁香叶油处理提高了超氧化物歧化酶、过氧化氢酶、过氧化物酶3种膜脂过氧化物酶的活性，但可溶性固形物含量与对照相比无明显差异。

L , the storage at 20℃ can decrease the cost of production of Typha latifolia.L and do not cause visible browning.

储藏温度越低，蒲菜的色泽越好，在 20℃下储藏可以降低生产成本而蒲菜不发生明显的褐变。

The lower the storage temperature; the better the surface color of Typha latifolia.

将产品 pH 值调整为 3.0 并添加 1‰的 L-半胱氨酸可以抑制这种褐变。

During the sterilization decrease the sterilization intensity or increase the sterilization is good to inhibit the browning of Typha latifolia.

在杀菌过程中，降低杀菌强度、升高杀菌温度有利于降低高温杀菌蒲菜的褐变程度。

L under high temperature sterilization. The condition of complexion of Zn2+ with chlorophyll to stabilize the chlorophyll to prevent the browning of chlorophyll in green Typha latifolia.L is studied.

并对利用锌离子与叶绿素高温复合反应稳定叶绿素以防止绿化蒲菜中叶绿素的褐变的工艺条件作了初步探讨。

Yali pear originated in our country is one of the major varieties of white pear lines.

鸭梨，作为原产于我国、白梨品系优良主栽品种之一，采后贮藏中很重要的一种生理病害是果心褐变。

Bake at 370° for 60 minutes, until browned and apples are tender.

在370°烘烤60分钟，直至褐变和苹果的招标。

The results showed that NaN3 had great effects on TCL growth. Some TCL after treatment got white or browning and died and grew slowly, and the number of regenerated plantlets was reduced, and the regenerated plantlets became abnormal with leaves crimpled and thicker. The RAPD reaction with 10 primers indicated that the molecule maps of RAPD had some polymorphisms which meant the sequence of DNA was changed.

结果表明，NaN3对类原球茎薄切片生长产生重要影响，部分薄切片白化或褐化死亡，再生类原球茎生长受到抑制，再生苗数量减少，部分再生苗畸变，叶片皱缩、变厚。10条RAPD引物的PCR检测发现，再生苗DNA序列发生了一定程度的变异，产生RAPD图谱带型多态性。

Possibility and mode of action of preventing brown turning in sucker explants fromBanana were studied.

研究了抗坏血酸预处理对防止香蕉吸芽外植体褐变的可能性及其作用方式。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
