Inoculating resistant and susceptible cultivars with Guignardia camelliae, the POD, PPO, CAT, PAL activities in the annual leaf cell increase rapidly. And the increment of POD, PPO, PAL activities in resistant cultivars were higher than susceptible cultivars.

自然和人工接种发病后，抗、感病品种体内保护酶(POD、PPO、CAT、PAL)的活性迅速提高，抗病品种增加幅度明显大于感病品种，但 CAT 酶活性变化无显著性差异。

In order to explore the mechanisms of auxin action and metabolism, as well as the changing characteristics of its relative enzymes, IAA content in strawberry fruits with different treatments was determined by HPLC. Content of IAA and the activity of IAO and POD in fruits treated by NPA or TIBA, the inhibitor of auxin transport, were analyzed to investigate the changing characteristics and possible source of auxin, as well as the relation among IAA, POD and IAO. Results were showed as the followings: there had a certain count of IAA in receptacles and achenes, and IAA content in achenes was higher than that in receptacles.

摘要为了探索草莓果实中生长素的代谢变化及其发挥作用的机理，利用HPLC定量测定了草莓果实发育过程中瘦果和花托中的吲哚乙酸，结合生长素运输抑制剂NPA和TIBA处理考察了草莓果实中IAA含量以及不同存在状态的生长素氧化酶和过氧化物酶活性变化，综合分析了草莓果实中IAA 的变化特性、可能来源及其与生长素代谢相关酶的关系。

While the content of IAA was significantly positively correlate with the activity of POD both during the early and later stage of strawberry fruit development, suggesting that IAO might play the crucial role in oxidized decomposition of IAA, yet POD might involve in the maintaining of dynamic balance of auxin and cooperat with it to promote the fruit development. These might put a substantive foundation to investigate the action mechanism of auxin in the development of strawberry fruits.

表明草莓花托中对IAA的氧化分解起主要作用的可能是IAO，而POD除了参与IAA分解之外，可能还与维持生长素的动态平衡、协同促进果实的生长发育有关。

Seed pods of Ibicella lutea, Martynia annua, and Proboscidea parviflora. No one has accused Martynia annua of being a carnivore. It just has shady relatives. Note the very spiny pod of Ibicella lutea and rather smooth pod of Proboscidea parviflora.

网站第二张图是三种植物的种子）左边的黄花单角胡麻种子布满棘刺；中间的 Martynia annua 并无列入食虫植物，它只是和亲戚长得有点像罢了；右边的 Proboscidea parviflora 种子则较为平滑。

A pot experiment was conducted to investigate the effect of soil water on protective enzymes of superoxide dismutase, catalase and peroxidase, and also on membrane lipid peroxidation including malonaldehyde and plasma membrane permeability in pea (Pisum sativum Linn.) leaf during flowering and pod-bearing stages under drought stress and water recovery conditions. Antioxidant ability of pea during flowering and pod-bearing stages was also analyzed.

为探讨不同水分条件对豌豆保护酶系统和膜脂过氧化的影响，采用盆栽人工控水试验方法，模拟干旱胁迫及复水条件，研究了不同水分处理对花荚期豌豆叶片超氧化物歧化酶、过氧化氢酶、过氧化物酶活性以及过氧化产物丙二醛含量和脂膜相对透性的影响，并对花荚期豌豆抗氧化能力进行了综合评价。

GA3 contents, POD activities and invertase activities started to increase significantly while IAA contents started to decrease significantly when plants entered the critical stage of flower-bud differentiation; GA3 contents, POD activities and invertase activities emerged high apex value while IAA contents emerged low apex value when plants entered stage of primar...

当植株进入花芽分化临界期时，叶片中GA3含量以及POD和转化酶活性均开始剧增，而IAA含量开始剧减；当植株进入第1侧花茎原基分化期和第2～3侧花茎原基分化期，叶片中GA3含量和POD、转化酶活性均出现一高峰值，而IAA含量出现一低峰值。可见，青花菜侧花茎每一级的花芽分化要求较高含量的GA3、较低含量的IAA和较高活性的POD、转化酶。

However,compared to Cd~(2+) stress alone, treatment of SNP+Cd~(2+) caused more increases in SOD,CAT and POD activities, a decrease of H_2O_2 level and MDA content in leaf and root ofmung bean seedlings. These results indicated that exogenous NO induced increases inSOD, CAT and POD activities, which scavenged H_2O_2 and resultantly inhibitedmembrane lipid peroxidation in leaf and root of mung bean seedlings under Cd~(2+) stress.

说明NO通过诱导膜保护酶活性的提高，降低了活性氧水平，从而使Cd~(2+)胁迫诱导的膜脂过氧化程度降低，这可能是外源NO明显缓解Cd~(2+)胁迫抑制绿豆幼苗生长发育的原因之一。

Histochemically, the results indicated that POD activity increased with the growth rate of callus within the same tissue; and lignin deposit density within the cell wall increased with the growth of callus over time, displaying a trend similar to POD activity alteration upon Hg(superscript 2+) imposition; Furthermore, more tracheary elements was observed in the callus tissue subjected to Hg(superscript 2+) than that in control.

组织化学定位结果表明：同一处理样品的过氧化物酶活性随着愈伤组织的生长进程而逐渐增强，且与Hg(上标 2+)浓度呈正相关；细胞壁中木质素沉积随着愈伤组织的生长而增加，与过氧化物酶活性变化趋势一致；Hg(上标 2+)处理的愈伤组织中导管诱导率大于对照。

A pot experiment was conducted with two soybean varieties (Di2003-1 and Hefeng25) and two main soil types in Heilongjiang Province to study the interactive effects of variety and soil type on the root morphology and nodule traits of soybean plants. Root samples were collected at the fifth trifoliolate stage, bloom-beginning stage, pod-beginning stage, full pod stage, seed-beginning stage, full seed stage, and full maturity stage for the analysis of root dry mass, root length, root surface area, average root diameter, nodule number, nodule fresh mass, and mass per nodule.

选取黑龙江省2种主要农田土壤类型和2个大豆品种（滴2003-1和合丰25），采用盆栽试验，分别于大豆第5片复叶展开期、初花期、结荚初期、结荚盛期、鼓粒初期、鼓粒期和完熟期取样，进行根系形态（根干质量、根长、根表面积和平均根直径等）和根瘤性状（根瘤数、根瘤鲜质量和单个根瘤质量）的动态分析，以研究品种和土壤类型对大豆根系形态特征的影响。
