查询词典 callus

For breed Powderblue, GGR treatment with density 50 mg/L was better for Callus-generated and rootage of quickset, the Callus-generated and rootage ratio increased 42.5% and 33.33%, compared with contrast.

结果表明：清水处理的兔眼蓝莓品种间插条愈伤组织产生率和生根率为园蓝最容易扦插成活，杰兔次之，粉蓝和S13较难扦插成活。

Result and Conclusion:All the media used could induce callus, while the results of callus redifferentiation were very distinct.

结果与结论：所用培养基均能诱导愈伤组织产生，但愈伤组织形成后的再分化结果却有明显差别。

The seeds of rice mutants with Ac/Ds elements inserted from rice variety Dongjin were selected and the callus were induced from scutellum of mature embryo. Ca(superscript 2+) with different concn. was added into the selected optimum enrichment, differentiation and rooting medium to study the effect of Ca(superscript 2+) on proliferation, differentiation and rooting of rice callus.

方法］选用水稻品种Dongjin的Ac/Ds插入突变株系的种子，从成熟胚盾片诱导出愈伤组织，在筛选出的最适增殖、分化及生根培养基中添加不同浓度的Ca(上标 2+)，研究Ca(上标 2+)对水稻愈伤组织增殖、分化及生根的影响。

Result Placing upward the scutellum of mature embryos could increase the callus induction rate obviously. The callus induction rates in different eultivars all reached as high as 80% by using 2 mg/L 2,4-D and adding hydrolisis casein.

结果结果表明：将成熟胚盾片向上放置可明显提高愈伤组织的诱导率；利用2mg/L 2，4-D并添加水解酪蛋白，可使不同品种小麦愈伤组织得出愈率均高达80％；此外，不同品种的出愈率随着2，4-D浓度的升高存在较大差别。

The callus derived from mesocotyl and vascular bundle of scutellum showed different cellular characteristics from scutellar epithelial callus in cultivar Aikoku.

More taxol is synthesized in the callus of young stem and leaf than inthe callus of others.

在5种外植体中，嫩茎和叶愈伤组织合成紫杉醇的能力较其它愈伤组织强。

According to brown degree of callus infected by Agrobacterium tumefaciens, the callus, about 25 days after inoculatation , was selected as explants for transformation and concentration of superpure sugrose was 3g/L in medium.

以农杆菌浸染后愈伤组织的褐化程度为指标，发现最适于转化的愈伤组织为花药接种后25天左右，培养基的最适超纯琼脂粉为3g/L。

Based on extrapolated organ shape criteria,we select ears that are in uninucleate period,carry out pretreatment in a 6~8℃ low-temperature condition for about 12 days, and callus induction rate can be enhanced in this way.② 1~2mm diameter should be the appropriate size for translocated callus,and plants grow to 4cm breeding for mature plants should be conducted in a timely manner.③ Get well down with sterilization,reduce contamination and strengthen greenhouse management,etc.

根据器官形态指标外推法选择花粉发育处于单核靠边期的幼穗，进行6~8℃低温预处理12d左右，可提高愈伤组织诱导率；②愈伤组织转移大小以直径1~2mm为宜，当绿苗长至4cm左右时及时进行壮苗培养；③做好接种材料、室内、人员的消毒和卫生工作，降低污染率，加强温室等的管理。

Were studied. The optimum growth cycle of stem callus of A. crenata was 25-30d. The size of inoculums greatly influenced callus growth rate of Ardisia spp.

接种量对愈伤组织的生长影响很大，朱砂根的茎愈伤组织的接种量在1.920-3.280g／瓶之间时与生长呈负相关关系。

To obtain more messages from Ardisia, some studies, such as characters of seeds germination and storage, factors influencing callus induction and growth, monitoring bergenin in callus of Ardisia spp and plant regeneration of Ardisia spp, were carried out. As a result, calli were obtained from nine species of Ardisia and bergenin, the major pharmaceutical element of Ardisia, was proved to exist in six of them when checked by HPLC. Plant regeneration systems were established from three species of Ardisia too. These works are all reported for the first time.

为更好地利用该属植物资源，本文对紫金牛属植物的种子萌发和贮藏，愈伤组织的诱导和培养，培养物中岩白菜素含量的检测，植株再生等问题进行了研究，首次成功地获得了紫金牛属9个种的愈伤组织并在其中6个种中检测到主要药用成分岩白菜素的存在，同时首次建立了该属3个种的再生体系。

Continuously improve the production mechanism, to provide customers with better quality products and services.
