In addition this study suggested that the wheat variety 98-10-30 and Batis had the same resistance when no aphids fed on them. However, the variety 98-10-30 had better resistance for S. graminum, and the variety Batis had better resistance for S. avenae when they were fed by aphids. The variety Amigo had better resistance for S. graminum under all situations.
同时明确了3个品种对两种蚜虫的抗性状况,即在前期无蚜虫危害时,品种98-10-30和Batis对两种麦蚜的抗性相当;在前期有麦蚜危害时,品种98-10-30对麦二叉蚜的抗性较好,而品种Batis对麦长管蚜的抗性较好;品种Amigo无论在任何处理下均对麦二叉蚜的抗性较好。

When the aphids were feeding on Ww2730 seedlings, the time to 1st probing was delayed compared to those on Xiaoyan22 and Batis, searching was interrupted before 1st probing, and 1st probing was shorter than that on Xiaoyan22 and Batis significantly. Duration of pd Ⅱ-1 on Ww2730 and Xiaoyan22 was much longer than that on Batis. Duration of pd in C waveforms on Ww2730 was longer than that on Xiaoyan22 and Batis remarkedly. Times and duration of G waveform on Ww2730 were more and longer. Times of spot G waveform on Batis were more than on Ww2730 significantly, but the duration was shorter than those on Xiaoyan22 and Ww2730. Total time of E1 waveform, max longest duration of E1 fractions and mean duration time of E1 fractions following E2 wavefrom on Xiaoyan22 and Batis were all longer than on Ww2730 statistically. There were no differenences among mean durations of 1st E1 wavefrom on three varieties, but mean durations of other E1 waveforms on Ww2730 and Xiaoyan22 were shorter than those on Batis. The other waveform parameters, include times and durations of F and E2 were all not different on three wheat varieties.It is suggested that the resistance mechanism of wheat variety Ww2730 to S.
麦长管蚜在品种Ww2730上口针开始接触叶面时间显著晚于小偃22和Batis,第1次持续刺探前的刺探次数显著多于小偃22和Batis,开始刺入叶面后第1次刺探的持续时间极显著短于小偃22和Batis;在Ww2730和小偃22上的PdⅡ-1的平均时间显著长于Batis;Ww2730上C波阶段2个Pd波间的间隔平均时间显著大于另外2个品种;在Ww2730木质部取食的次数和时间显著大于其它2个品种;Batis上的点G波的次数极显著地高于Ww2730,而平均持续时间极显著短于小偃22和Ww2730;在Batis和小偃22上E1波的总时间,E1波的最大值、跟随E2波的E1波的平均时间均显著大于Ww2730;3个品种间第1次E1波持续的时间差异不显著,但Ww2730和小偃22上其它E1波持续的时间极显著少于Batis;3个品种上其它波形参数,包括F波的次数和总时间、E2波的次数和总时间没有差异。

Of the 36 tussah silkworm varieties, the Nei's genetic diversity index was 0.3243±0.1515, and Shannon information index was 0.4871±0.1975, suggesting that bivoltine tussah silkworm varieties are still rich in genetic diversity even having been conserved in the same place for quite long time. Nei's genetic identity of the 36 varieties ranged from 0.4959 to 0.8347, 96.59% of which was above 0.6, revealing large similarity between different varieties. A clustering analysis showed that these varieties formed two separate clades, one of which included varieties bred by the institute and the other included imported varieties from other provinces or countries.
供试品种资源的Nei氏遗传多样性指数为0.3243±0.1515,Shannon信息指数为0.4871±0.1975,表明长期同地保存的二化性柞蚕品种资源同样具有丰富的遗传多样性;供试品种的Nei氏遗传一致性范围在0.4959~0.8374之间,达0.6以上的占96.59%,表明多数品种资源的相似程度较高。36份品种资源分别以辽宁省蚕业科学研究所育成种为主和以国内外引进种为主聚为两大类群。

In order to clarify the rules of POD isoenzyme in the hazelnut, identify their blood relations between female, male and filial generations and select the superior parents for cross-breeding, we have studied the characteristics of peroxidase isoenzyme which are distributed in the 34 hazelnut varieties or lines by polyarclamide gel electrophoresis, The results showed that:POD isoenzymes of Corylus heterophylla Fisch, Corylus avellana L, and the hybrid of Corylus heterophylla Fisch × Corylus avellana L had obvious difference; some hybrids had lost P10 spectrum band of parents; the enzyme spectrum of 32 hybrid hazelnuts produced 'new hybrid spectrum bands'that could be considered as a mean to identify hybrids.
为了阐明过氧化物同工酶在榛品种中的分布规律,探讨平榛、欧榛及其杂种榛之间的亲缘关系,选育优势杂交亲本,本试验采用聚丙烯酰胺凝胶垂直电泳,研究了34个榛品种成熟叶过氧化物酶同工酶酶谱特征,结果表明:平榛、欧榛及其平欧杂种榛品种间酶谱具有较大差异;有的杂种品种遗失了父母本共有谱带P10;32个平欧杂种榛品种出现了双亲所不具有的新酶带,可作为鉴别杂种的一条途径。

Results showed that contents of IAA and ABA in peduncle, bourse and the tissues around abscission zone among several cultivars were very different, but their trend of change was similar, IAA content decreased and ABA content increased toward harvest time for all the cultivars. Ethylene evolution in fruit of the cultivars with higher preharvest drop was evidently higher than the cultivars with less preharvest drop. Cellulase activity in the tissues around abscission zone of the cultixars with higher prehanest drop rapidly increased toward harvest time.
结果表明:不同品种果柄、果台和离层部位组织中IAA和ABA含量变化有差异,但它们变化的总趋势相似,都是随着果实成熟IAA含量下降,而ABA含量上升;不同品种的成熟果实中乙烯发生量有很大差异,以落果多的品种显著大于落果少的品种;采前落果重的品种离层部位组织中细胞壁分解酶的活性在果实成熟期急剧增加。

Therefore selection breeding of new cultivars with great ornamentalvalue and cold-resistant cultivars are very important Sexual crossing breeding and bud mutation selection breeding are conventional breedingmethods in Floribunda roses.
但因为其品种较为单一,且基本都依靠进口,缺乏具有我国自主产权的优良丰花月季品种,而且我国北方由于气温低,还没有可以广泛栽培并能露地越冬的品种,因此培育观赏性高的新品种和抗寒品种成为当前园林植物育种的热点。
