- The arrangement of cellulose microfibrils in the guard-cell walls causes the guard cell to increase in length rather than width as it takes in water. 保卫细胞可以因为自身紧张度的改变而规律性的开闭。
- With the increase of chromosome ploidy of pepper, the stomatal density of leaf declined obviously, and the chloroplast number and the width of guard cell rose notablly. 结果显示:随辣椒染色体倍性的提高,叶片气孔密度呈明显下降趋势;保卫细胞叶绿体数与保卫细胞横径呈明显上升趋势;
- The stoma and guard cells are collectively called the stomatal apparatus. 临近保卫细胞处常存在变形了的表皮细胞,被称为副卫细胞。
- In the presence of CAT or DPI,the guard cell treated with SA l00llmolth showed increase in DCF fiuorescence only in theregions of chloroplasts located, but the production of H2O2 was inhibitCd in the regions ofplasma membrane (Figure l2,Figure l3). 当在CAT和DPI存在情况下SA处理后保卫细胞内H_2O_2产生仅在叶绿体部位,而质膜附近的DCF荧光增强受到了抑制(图12;图13)。
- Results indicated that the ploidy of pepper could be identified effectively through the observations on stomatal density, cholorplast number, and the width of guard cell of pepper. 表明叶片气孔密度、保卫细胞叶绿体数、保卫细胞横径可作为鉴定辣椒染色体倍性的有效依据。
- The plant was diploid when the number of chloroplast in stomata guard cell was less than 16, otherwise it was polyploid, and the rates to identify diploid and polyploid cultivars were 92.8% and 94.2%. 以16为界来判定倍性,叶绿体数少于16的为二倍体,大于或等于16的为多倍体,对二倍体和多倍体判定的准确率分别达92.;8%25和94
- When the sun rises, the guard cells inflate and bulge to open the stomata, and photosynthesis begins. 当太阳升起时,这些保卫细胞充气并膨胀,打开了气孔,即开始了光合作用。
- The dog kept a vigilant guard over the house. 这只狗警惕地守护着这所房屋。
- Blue light may be a very effective light for the respiration of the guard cells. 蓝光在保卫细胞之呼吸作用是非常有效的光。
- There are a few stomatal apparatus in abaxial.The surface of guard cells and accessory cells are smooth. 气孔器仅见于下表皮,分布稀疏,副卫细胞和保卫细胞表面光滑。
- A correlation has been established between ploidy and chloroplast number in the stomatal guard cells. 同一小孢子再生植株群体内的不同倍性植株的叶绿体数平均值差异极显著。
- Two guard cells together encircle each stoma and control the opening and closing of the stomatal aperture. 每个气孔由两个保卫细胞包围来控制气孔的开闭。
- Stoma of walnut is a good specimen for scientists to exactly discriminate the boundary of stomata with outer ledges of ventral wall of guard cells. 核桃的气孔为人们正确地区分气孔的边界与保卫细胞内侧壁的外缘提供了很好的样本.
- The cells are typically platelike and closely packed together except where they are modified for a particular function, as are guard cells. 表皮细胞是很有特色的一个细胞层,除了某些具有特殊功能部分细胞,如保卫细胞外,通常都紧密的排列在一起。
