查询词典 cultivars

The paper studied the effects of five kinds of photoperiod(16、 14、 12、 10、 8h light/d) on the two cultivars of camellia japonica('White snow tower' and ' White-red peony').The morphological and physiological indexes relative to growth were measured. Then the critical daylength and the flower bud differentiation of ' White snow tower ' and ' White-red peony' were defined. The results indicated:(1)Camellia japonica was long-daylength plant, and different cultivar had different critical daylength,the critical daylength of 'White snow tower' was about 14 h light/day,while the critical daylength of 'White-red peony' was about 12 h light/day.

In this research, we employed 260 wheat cultivars selected from the different wheat-growing areas in China to be as materials for identifying vernalization gene loci of Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 by using STS markers and by field growth examination together, in order to make clear the effects of growth habit in wheat on dominant-recessive regarding four vernalization gene locus.

本文选取来自中国各麦区的260份小麦品种，用STS标记对其Vrn-A1、Vrn-B1、Vrn-D1和Vrn-B3四个春化基因位点进行检测，并结合小麦田间生长情况记录，探讨春化基因的4个位点显隐性情况对品种冬春性的影响。

Ug99 could be called a superior virulent race to widely-used and Sr31-carrying Chinese wheat cultivars or stem rust resistant sources.The number of virulent genes contained in Ug99 was more than the total carried in all Chinese stem rust races.For instance,the virulence of Sr5,Sr9e or Sr11 was the typical races.However,besides the virulence of Sr5,Sr9e and Sr11,Ug99 contains additional virulence of Sr21,Sr31and Sr38,which have never been found in Chinese stem rust races.

Ug99堪称我国的超毒小种，我国最典型的秆锈菌小种只能分别克服或Sr5或Sr9 e或Sr11单基因抗性，而Ug99不仅具有Sr5、Sr9 e、Sr11的联合毒力，而且还具有Sr21、Sr31、Sr38的联合毒力，而我国从未有小种能克服后者的抗性。1B/1L(含Sr31)易位系曾是我国使用的重要秆锈抗源，必对Ug99高度脆弱，我国118份小麦品种在KARI的测定结果表明，高感品种频率98.3%。

These results corresponded to a higher lignin content measured by the Klason method and stem strength and a lower lodging index in H4564 than in C6001 at the heading and milky stages. Therefore, the TaCM mRNA levels, protein levels, and enzyme activity in developing wheat stems were associated with stem strength and lodging index in these two wheat cultivars.

马庆虎研究组分离了在小麦茎秆中高度表达的木质素合成关键酶基因-咖啡酸甲基转移酶基因，通过生化和转基因分析证明COMT 在控制松柏醇型木质素上发挥着重要作用，COMT基因的表达在抗倒伏小麦生长发育后期明显高于易倒伏品种，这种基因的高表达进一步促进了COMT酶蛋白和酶活力的提高，并增强了木质素的合成。

Breeding wheat cultivars with low deoxynivalenol content is an effective approach to control the toxin contamination in wheat grains caused by wheat scab. In this paper, two methods for the determination of DON content in wheat grains, DON test-HPLC and GC-MS, were compared.

为选育赤霉病毒素含量低的小麦品种，减轻赤霉病危害，在比较了免疫亲和柱液相色谱法(DON test-HPLC)和气质联用法测定小麦中毒素含量的特点的基础上，利用两种方法对自然发病和赤霉病菌人工接种的小麦籽粒DON含量进行测定。

Three wheat spindle streak mosaic viruses resistant cultivars ('Yining Xiaomai', 'Xu87-633', and 'Xifeng') and one susceptible cultivar ('Zhen9523') were used as parents of 3 crosses in this experiment. WSSMV resistance of the parents, F1, and F2 was evaluated under field condition.

选用3个抗梭条花叶病的小麦品种&仪宁小麦&、&徐87-633&和&西风&为抗病亲本、以感病品种&镇9523&为感病亲本配制了三个杂交组合，对四个亲本及其杂种后代（F1及F2代）单株的田间抗病鉴定表明，三个抗病亲本的抗性均由核基因控制，为显性遗传方式。

In the study, two cultivars,"Maru" and "Centurion" fruits were extracted with water and study rats were tube-fed 1 ml of the blueberry extract daily for six days.

在实验中，两种栽培品种，&Maru&和&Centurion&从中提取蓝莓浓缩物，此提取物用于实验的老鼠，连续六天，每天用食管喂食1毫升的蓝莓浓缩物。

In the experiment, the tea plant shoots were cultured in vitro, and inoculated artificially. The result showed the disease condition in vitro was basically consistent with that of the tea plantation in nature. Therefore, we thought this identification method of tea plant resistance to tea brown blight was feasible, especially a large number of cultivars.

本试验采用离体插枝培养法，人为造成伤口、人工接种并保湿对茶树品种进行抗性鉴定，室内人工接种与田间自然发病的情况基本一致，因此，可以认为此方法对茶树品种抗云纹叶枯病鉴定是可行的。
