查询词典 stoma

In many xerophytes and in some conifers of cooler climates, where soil water may be difficult to obtain in winter, the guard cells-and hence the stoma-are sunk in pits in the epidermis, often protected by hairs form passing air currents. TRANSPIRATION rates are thus greatly reduced, while allowing gaseous exchange for photosynthesis.

一些旱生植物和寒冷气候带的针叶树在冬季很难从土壤中得到水分，因此它们的保卫细胞和气孔在表皮上下陷成为气孔窝，常被表皮毛保护，可以在满足光合作用所需的气体交换的同时防止通过的气流带走大量水分，大大降低了植物呼吸率。

The main results were as follows: The Xinjiang floating dust-fall caused the winter wheat leaf upper epidermis stoma density to significantly decrease.

主要研究结果如下：新疆浮尘使拔节期和盛花期的冬小麦叶片上表皮气孔密度显著减少。

Here are the results: there are no clear difference in the length and width of leaf epidermis stomatal apparatus, stoma density and vascular bundle area in 1st internode below the ear between cold and warm type wheat. The vascular bundle area in 2nd internode below the ear of cold type wheat is obvious smaller than warm type wheat's. There are clear difference in the vascular bundle number in unit transverse area of 1st internode and 2nd internode below the ear and the rate of the total area of vascular bundle and the transverse area of wheat stem between cold and warm type wheat.

研究表明，冷、暖型小麦叶表皮气孔器的长度和宽度、气孔密度、穗下节间中维管束面积均无显著差异；冷型小麦倒二节间中维管束面积明显小于暖型小麦；冷、暖型小麦穗下节间、倒二节间单位横截面积中维管束数目、维管束总面积占茎横截面积的百分率均有显著差异。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
