查询词典 callus

According to the browning phenomenon of Castanea mollissima in plant tissue culture and the activity of the peroxidase and polyphenolic oxidase, the results of my study indicated that the activity of PPO has relativity with the browning of the callus, that is the higher activity of enzyme,the more severity of browning.But POD was not as PPO.

本文对褐变的机理进行初步研究，分别统计和测定培养期间褐变率、PPO活性、POD活性，研究培养过程中酶的活性变化与外植体褐变的关系，结果表明：板栗组织培养过程中，PPO活性与褐变存在显著的相关关系，PPO活性高的处理其褐变率也较高，POD活性与褐变之间无相关性。

RESULTS: Four weeks following repair, CT showed that callus formation appeared in coronal skull defects. 3D reconstruction still demonstrated some defects. Hematoxylin and eosin staining displayed defects were fibrous connective tissue, with the presence of chondroid tissues.

结果：修复后4周，冠状位CT显示颅骨缺损区可见骨痂形成，三维重建仍显示有缺损；标本苏木精-伊红染色显示缺损为纤维结缔组织，并有软骨样组织形成，Mallory三色染色标本呈淡蓝色。

Mallory trichrism staining exhibited light blue samples. Eight weeks following repair, CT showed round blunt defect edges in the coronal position, which had bony pustute connection with gel materials. Density at the defect region significantly increased. 3D reconstruction suggested that defects became small. After hematoxylin-eosin staining, abundant fibrous connective tissue appeared in defect regions, with bony tissues. Mallory trichrism staining revealed that maroon mature bone tissues were found, surrounded by light blue chondroid tissues. Twelve weeks following repair, coronal defect regions were filled with callus. 3D reconstruction showed that defects were repaired. Defect region and surrounding bony tissues had bony connection, with thick bone trabecula and mature Haversian system.

修复后8周，冠状位CT显示缺损边缘圆钝，与凝胶材料有骨性突起连接，缺损处密度增高明显，三维重建显示缺损范围较之前有所减小；标本苏木精－伊红染色后缺损部可见大量含血管成分的纤维结缔组织，有骨样组织结构形成，Mallory三色染色显示有褐红色成熟骨组织形成，其旁边有淡蓝色软骨样组织修复后12周，冠状位CT显示缺损区基本被骨痂填满，三维重建示缺损基本修复；缺损区域和周围骨组织形成骨性结合，骨小梁粗大，哈弗氏系统成熟。

Studies on callus induction, adventitious shoot regeneration of Cirsium japonicum DC. var. takaoense Kitamura using leaf and stem-node as explants were conducted with different strength of MS medium, sucrose concentration and growth regulator combination in this investigation.

METHODS:Using Coptis chinensis as plant material,the effect of the rare-earth elements Yb3+ and Eu3+ at various concentrations on the callus growth and the content of alkaloids were investigated.

以药用植物黄连为材料，研究不同浓度的稀土化合物对愈伤组织鲜重增加和生物碱含量的影响。

Spikelets alike (except Cortaderia , Elytrophorus ), laterally compressed, fertile florets several, uppermost florets reduced, disarticulating between florets; floret callus usually bearded, short and obtuse or elongate; glumes persistent, variable in length, shorter than lemmas to as long as spikelet, usually membranous, 1–9-veined, apex acute to acuminate; lemmas rounded on back, hyaline to leathery, glabrous, pilose or villous, hairs sometimes in tufts,(1–)3–11-veined, apex entire or 2-lobed, awnless or a straight or geniculate awn with flat twisted column arising from apex or sinus, lobes often extended into bristles; palea well developed.
