The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.
结果表明：水培后根冠不明显，淀粉体较少，多糖类物质较少而土培根根冠体积较大，淀粉体较多，多糖类物质多，土培根PAS反应强烈；水培根表皮厚度比土培根小，水培根根毛少或退化消失；水培根皮层薄壁组织发达，细胞大型，壁薄，细胞间隙中含有溶生性通气组织，土培根皮层未见通气组织。

Three QTLs detected for maximum adventitious root length in solution culture, total root dry weight in both solution culture and paper culture accounted for about 20%, 23% and 13% of the total variations, respectively.
其中溶液培养中的最长不定根长、总根干重和旱作培养中的总根干重检测到的QTLs位点对总变异的贡献率分别为 2 0 %、2 3 %和 13 %左右；旱作培养中的最长不定根长、不定根数、根冠比和溶液培养中的根冠比仅检测到上位性位点，对表型变异的贡献率在 12 %～ 61%之间。

As pairs of connected ramets were subjected to reciprocal patchiness of light and nutrients, stolon connection between the two ramets significantly enhanced biomass of both ramet growing in low light intensity but high soil nutrient condition and ramet growing in high light intensity but low soil nutrient condition as well as whole ramet pairs (consisting of LH ramets and HL ramets).
当生长于高光照低养分条件下分株与生长于低光照高养分条件下分株之间的匍匐茎连接时， 3种克隆植物HL分株、LH分株以及整个分株对系统(HL分株+ LH分株)的生物量均得到显著提高。同时， LH分株根冠比显著增加，而HL分株根冠比显著下降。

To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic response. The negative phototropic bending could be induced prominently by blue/UV light, while not be induced by red and far-red light.
为了研究水稻根负向光性的光受体，观察了光质对稻根的负向光性效应，用紫外－可见分光光度计测定了水稻根冠浸提液的吸收光谱，并对根冠中的蛋白质进行了SDS-PAGE电泳分析。

The phenomena of function equilibrium between root system and canopy was observed.
本研究从植株整体的物理性质（源汇强度和韧皮部传输性质）出发，从更低的层次上模拟观察到了在环境水分条件发生变化时植株根冠间存在的功能平衡现象，并对此作出了机理性的解释，说明了当同化物的传输受维管束中压力势控制，而且韧皮部与所在器官的水势保持平衡状态时，根冠之间就会存在功能平衡关系，这说明了根冠间的功能平衡现象应该是维管植物适应环境变化过程中的一种普遍现象。

The primary result reveals that the normal expression of Clone C103 is profoundly regulated by endogenous auxin in maize root tip, and the expression of Clone C103 maybe has some relationship with statolith in the periphery of central cap.
由此表明玉米根尖内源生长素影响根冠特定基因Clone C103的正常表达；Clone C103在根冠的表达位置推测该基因正常表达可能与中心根冠外周的平衡石有关。

The sucrose content of the low R/S line "NAU-LR-04" was higher than those of three highR/S lines at all stages, while the fructose content was lower in "NAU-LR-04". Changes ofactivities of sucrose synthase were similar to sink activities in all the lines, and theactivity of SuSy in low R/S line is higher than those of high R/S lines.
结果表明，不同根冠比肉质根的库活性变化基本一致，"破肚"后一周内达到最大；可溶性总糖、果糖、蔗糖含量初期下降，"破肚"期降至最低值，其中低根冠比品系'NAU-LR-04'蔗糖含量一直高于其它高根冠比品系，而其果糖含量则相对较低。

-
The promeristem is consisted of three groups of initial cells, which have typical cytological characteristics of meristem cells. The primary meristem is composed of calyptrogens, primordial epidermises, periblems and pleromes. Both the calyptrogens and the primordial epidermises initiate from the same layer of initial cells.
原分生组织由3群原始细胞组成，其细胞具有典型分生组织的细胞学特征；初生分生组织包括根冠原、表皮原、皮层原和中柱原，其中根冠原和表皮原具有相同的起源。
