查询词典 root

To investigate the response of plant growth and antioxidant system to changes of root temperatures, roots of six cucurbit plants were exposed to three different root-zone temperatures: low (14℃), middle (24℃) and high (34℃), while aerial parts of plants were maintained at the same natural ambient temperatures (23-33℃). The six cucurbit plant species could be classified into three groups with figleaf gourd and turban squash being I group (heat-sensitive but cold-tolerant), cucumber and melon being II group (heat- and cold-sensitive) and bitter melon and wax gourd being III group (heat-tolerant but cold-sensitive), i.e.

为了探究植物生长与活性氧代谢对根际温度变化的响应，以六种温度敏感性不同的瓜类作物为试材(组Ⅰ，黑籽南瓜与美洲南瓜，耐冷但热敏感型；组Ⅱ，黄瓜与甜瓜，冷敏感与热敏感型；组Ⅲ，苦瓜与冬瓜，冷敏感但耐热型)，分别将其根系置于不同的温度环境中：低(14℃)、中(24℃)与高(34℃)三种温度条件下，而地上部保持与外界空气相同的温度(23-33℃)环境中。

Among three auxins , IAA at low concentration was the best for growth of Type Ⅰ hairy root, while 1mg/l IBA was the most suitable for growth of Type Ⅱ hairy root.

在发状根的继代培养基中添加外源生长激素（IAA、IBA、NAA），低浓度的IAA更适合于Ⅰ型发状根的增殖培养，而在促进Ⅱ型发状根的增殖和侧根形成方面，1mg/lIBA的作用最强。

Cytokinins move through the plant less readily than auxins or gibberellins and appear to move in opposition to auxins—from root upward to shoot, not shoot downward to root.

The leaf area index, photosynthetic potential and dry matter accumulation were lower for the SHY rice than those for the CK at the early growth stage, and their differences were not significant between the two rice types at heading, and were greater for the former than the later after heading. The root-shoot ratio at each growth stage, root bleedings from heading to maturity, grain-leaf ratio, translocation percentage of the matter from stems and sheaths and harvest index of SHY rice were greater than those of CK.

It has only been reported in a small number of trees (e.g., Sperry et al. 1994, Ewers et al. 2001). Diurnal refilling via root pressure has been reported in some crop species (Tyree et al. 1986, Stiller et al. 2003), but it is unclear whether trees employ root pressure for daily recovery of hydraulic conductivity.
