Using polyacrylamide gel electrophoresis with the staining of the enzymes,the constitutive isoenzyme components of peroxidase and esterase in three subtropical crops i.e., rice (Oryza sativa L. subsp. Hsien, Ting), cucumber (Cucumis sativa L.) and Agave (Agave sp.) with different degrees of tolerance to chilling temperature were studied.The isoenzyme of peroxidase exhibited significant variation in the three species studied as well as in the cultivars within the species. It was found that the number of component bands varied with the species and the cultivars. No matter whether the temperature was chilling or normal, the more tolerant cultivar usually had 1 to 6 more bands than the non-tolerant ones. Under the chilling temperature, the cultivars of different chilling sensitivity in rice, cucumber and agave all showed distinct change in the isoenzyme composition of peroxidase. The more chilling-tolerant lines had higher activity in peroxidase as well as additional isoenzyme component(s).The isoenzyme of esterase under the chilling temperature also showed some increase in activity and in the number of component bands, But, it didn't show significant difference between the lines of different sensitivity. In rice cultivar Zhen-zhu-ai, there was no variation in esterase isoenzyme composition when it was treated with the chilling temperature.The experimental results indicated that the activity and the isoenzyme component of peroxidase were strongly affected by the temperature while those of esterase were relatively stable regardless of chilling effect. It seemed that the number of isoenzyme band and their activities varied which was closely related to the difference in tolerance. Therefore, the resistance of plant to adversed temperature is closely related to the enzyme system and its change in the functional activity.

过氧化物酶同工酶在各植物种和品种之间存在着明显的差异,同工酶区带数随着物种和品种而变,不论在常温或低温下,一般抗冷性强的比抗冷性弱的多出1~6条区带。低温处理后水稻、黄瓜、龙舌兰麻各品种均可观察到显著的变化,除皮带麻低温处理后同工酶区带减少,某些区带活性减弱外,其余各品种均出现1~3条新的同工酶区带,越耐冷的品系区带活性越大。酯酶同工酶在低温下,除水稻的珍珠矮酶谱的区带数不变,皮带麻某些同工酶区带减少外,其余品种有些出现了新的同工酶区带,有些区带则增强了活性。试验结果表明植物过氧化物酶的活性和同工酶区带数明显地受温度所影响,而酯酶受低温影响相对比较稳定。过氧化物酶和酯酶同工酶区带的数目及其相对活性的改变似乎与植物的抗冷力有关,亦即植物对不良温度抵抗力的水平与植物酶系统的合成和它的功能活性的改变有关。

Cold injury which influence riee production in different rice growing countries oc- curs at various growth stages.The degree of cold injury depends on the air or water temperature,the cropping pattern,the growth stage of the rice and other factors.It is generally aeeepted that cold tolerance of rice at one stage is different from another stage.However,Okabe and Toriyama reported that varieties seem to respond simi- larly to cold temperature at different growth stages.Some varieties have been found to be tolerant...

Cold injury which influence riee production in different rice growing countries oc- curs at various growth stages.The degree of cold injury depends on the air or water temperature,the cropping pattern,the growth stage of the rice and other factors.It is generally aeeepted that cold tolerance of rice at one stage is different from another stage.However,Okabe and Toriyama reported that varieties seem to respond simi- larly to cold temperature at different growth stages.Some varieties have been found to be tolerant at different growth stages. The purpose of this experiment is to find whether cold tolerance scores at different growth stages of different kinds of riee are correlated or not.

从国际水稻研究所种质库取得50个水稻品种,其中包括粳型品种12个,釉稻18个,爪哇型品种10个,釉×粳杂种3个,以及野生稻7个。在芽期、苗期、移栽期、孕穗期、开花期,进行了耐冷性的测定。结果指出,在不同的水稻类型中,其耐冷性的次序为:粳稻>爪哇型>秈稻>野生稻。从本实验所采用的有限量的品种来看,在苗期粳型品种的耐冷性比其它类型好;在开花期某些爪哇型品种比粳型品种好;在芽期和苗期之间,以及在芽期和开花期之间,其耐冷性有明显的正相关。在其它时期之间未找到这种相关性。这指出,在特殊地区的低温发生时期的一定生育阶段中,进行筛选是必要的。

The cold tolerance of maize local varieties,hybrids and inbred lineswas evaluated at different growth stages under natural and controlled lowtemperature conditions.The results indicated that the differences in coldtolerance of various maize genotypes were represented by the followingindices.germinating energy,seedling emergence,temperature response,dry and fresh weight of seedling,rate of grain filling,dry matteraccumulation of grain and cell membrane permeability.Under the givenlow temperature condition cold tolerance was positively correlated withcell dehydration ability,and was negatively correlated with the extentfo leaf wilting The extent of leaf wilting was positively correlatedwith the electrolytes and percentage of K~+ exopermeating of cell.Theauthor suggests that for the evaluation of cold tolerance of maize inJilin province attention must be paid to the following three growthstages,i.e.germination,seedling and seed filling stage,taking theearlier stage as the key point.

在玉米不同生育时期,采用自然低温和人工控制低温研究玉米的地方品种、杂交种和自交系的种子发芽势、出苗指数、感温指数、幼苗干鲜重、籽粒灌浆速度、籽粒干物质累积和细胞膜透性等7个指标的耐冷特征。结果表明:在一定低温条件下,耐冷性与细胞耐脱水力成正相关,与叶片萎蔫度成负相关。叶片萎蔫度与细胞的电解质和钾离子外渗率成正相关。作者认为:吉林省玉米耐冷性研究应重视种子萌动、苗期和灌浆期,并以生育前期为重点。
