In the broad-leaved Korean pine climax forest, the fine root climax production of the community occurs in July and October, but the dominant arboreal species, understory arboreal species and fine roots of grass have a different production dynamics. It is important to sort the fine root species because accurate fine root production sources have a different fine root dynamics.

在原始阔叶红松林中，群落细根的生长高峰发生在7月和10月，但其中主要树种、其他木本和草本的细根有着不同的生长动态，所以在计算细根生产量时应该分类计算，才会得出较为准确的结果。

The study is carried out that the comparison of fine root production, decomposition and distribution along with Korean pine and broad-leaved climax forest succession; the fine root contribution to the belowground C and N storage along with Korean pine and broad-leaved climax forest succession; and the comparison of belowground C and N storage among the Korean pine and broad-leaved climax forest, three dark-conifer forests, a betula ermanii forest along altitude.

Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.

施肥时期对根系也具有明显的影响，与灌水前施肥相比，灌水后施肥有利于促进根系在上层土壤中的生长和分布；钙镁肥的施用能增加5~15cm土层根重，但对表层根的生长不利，施肥时期和钙镁肥施用与否对根系活力的影响也较大。

The extracted liquid at 0.2 g/ml could inhibit the growth of vegetable root, but had some promotion on growth of vegetable stem. The extracted liquid at 0.4 g/ml had the strong inhibition on the growth of vegetable root, but its inhibition on growth of vegetable stem was greatly variable in different species.

The results showed that the growth of root tips in liquid medium was better than that in agar-solidified medium and solid-liquid two phase medium, for that increasing agar concentrations in medium will reduce the root growth; darkness was beneficial for Fraxinus mandshurica root tip culture in vitro; as the carbon sources, sucrose was better than glucose and maltose as the carbon ...

结果表明，不添加琼脂的液体培养基对根尖的生长较添加琼脂的固体培养基和固—液培养基好，原因是增加琼脂的量会抑制根的生长；暗培养比光培养更有利于水曲柳离体根尖的培养；蔗糖作为碳源的效果较果糖和麦芽糖好，其中以3%的蔗糖对离体根尖的生长效果最好。

Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

During root primordia initiation,large amount of starch depleted,the amount of protein,free amino acids and peroxidase activity increased.

boletus edulis：牛肝菌

在纯培养条件下,研究了外生菌根真菌---美味牛肝菌(Boletus edulis)、铆钉菇(Gomphidius viscidus)、双色蜡蘑(Laccaria bicolor)、褐疣柄牛肝菌(Leccinum scabrum)在不同质量浓度DDT处理下的生长效应、耐受性和生理响应.结果表明:DDT没有影响外生菌根真菌的生长模式,

clinostat：回转器

其实,将植物放在不断旋转的回转器(clinostat)上进行的生长试验,知道根向下生长、茎朝上生长的原因是重力加速度. 近年来试验证明,在无重力作用的太空中,将植物横放,茎和根仍径直地生长,不会弯曲生长,进一步证实重力决定茎、根的生长方向.

coleorhiza：胚根鞘

胚较小,位于籽粒一端基部的一侧,胚由胚芽和包在胚芽外的胚芽鞘(coleoptile)、胚根和包在胚根外的胚根鞘(coleorhiza)、胚轴、子叶组成. 胚芽包括幼叶和生长锥;胚轴短,上接胚芽下连胚根;只有一片发育的子叶,着生于胚轴一侧,

cytokinin：细胞分裂素类

生长素主要被用于诱导愈伤组织形成,诱导根的分化和促进细胞分裂,伸长生长.在促进生长方面,根对生长素最敏感.在极低的浓度下,(10-5~10-8mg/L)就可促进生长,其次是茎和芽.(3)细胞分裂素类(cytokinin) 这类激素是腺嘌呤的衍生物,

Dark：暗的

与之相反,站在它对面与之抗衡的是晦暗的( dark )、阴性有( feminine )、俗世的( earth - bound )本原(阴),它的情感性( emotionality )和本能性( instinctiveness )是从遥不可及的时间深渊中生长出来的,是从连绵的生理连续性的根上生长出来的.

Hairy root：毛根

发根农杆菌中含有Ri质粒,其T-DNA在Vir基因的协助下整合进植物的核基因组,引起宿主植物发生毛根(hairy root)病,形成毛状根. 毛状根能够在无激素的培养基上生长,并且在液体培养中的生长速度大于相应的细胞培养物和未转化的根培养物.

hydrotropism：向水性

根的向水性(hydrotropism)也是一种向化性. 当土壤干燥而水分分布不均时,根总是趋向潮湿的地方生长,干旱土壤中根系能向土壤深处伸展,其原因是土壤深处的含水量较表土高. 香蕉、竹子等以肥引芽,也是利用了根和地下茎在水肥充足的地方生长较为旺盛的这个生长特点.

Rhizopus：根霉

(二)根霉(Rhizopus)根霉与毛霉同属毛霉目,很多特征相似,主要区别在于,根霉有假根和匍匐菌丝. 匍匐菌丝呈弧形,在培养基表面水平生长. 匍匐菌丝着生孢子囊梗的部位,接触培养基外,菌丝伸入培养基内呈分枝状生长,犹如树根,故称假根,

Digitaria ciliaris：升馬唐

一旦番茄和紫花苜蓿的根接触到黑核桃的根,前二者就将死亡;刺槐树皮分泌的挥发性物质,能抑制多种草本植物生长;小麦提取物能抑制反枝苋(Amaranthus retroflexus)、繁缕(Stellaria media)、升马唐(Digitaria ciliaris)等的生长;一些水稻

root tip：根尖

(1)根尖 根尖(root tip)指的是主根或侧根的尖端,是根的最幼嫩、生命活动最旺盛的部分、也是根生长、延长以及吸收水液的主要部分. 无论一年生或多年生植物,根尖都包含根冠、分生区、延长区和成熟区4个从顶端向后顺序排列的部分(见图).
