生根

The results were as follows:The unit-roots characters (weight, length etc.) and 15N absorption decreased progressively downward. 15N absorbed by any unit roots could be transported from root to tiller and from tiller to tiller, but the transporting ratio was different.The pattern was as follows: when 15N was offered to total roots of plant or only to primary roots, it was transported to main stem and then decreassingly to tillers from lower unit to upper one, when 15N was offered to n unit-root, it was transported to n unit tillers, then to n + 2 or n-2 unit tillers , followed by n + 1 or n -1 unit tillers , and finally to other unfeed roots.

各单位根吸收(15)~N后，蘖根之间，蘖蘖之间皆可互相运转，但其运转比例不同，其功能模式是：(15)~N喂全株根或专喂初生根，则先供给主茎，其次是分蘖，而且随蘖位升高而递减；喂n单位根，则先供给n单位本身，其次是n+2或n-2单位的蘖，然后是n+1或n-1单位的蘖，最后是未喂(15)~N的根系。

Cultivars which are vegetatively propagated ,are genetically identical to the source plant and should be adapted to the same conditions as the source plant.

除了监测空气温度以外，监测土壤温度也是相当重要的，热介质对于种子萌发和一些品种插条生根是很重要的。

And then adding NAA at low concentration in MS was used to give rise to roots. We also found that lower level of hormone could control effectively browninng and vitrifaction during the culture and G1 n (6mg/L) and AgNOj (2mg/L) supplemented in shoot induction media could improve the shoot information rates apparently (about90%).The whole period of plant regeneration from leaflets of peanut could be divided as five steps: germination - shoot induction -shoot elongation-rooting- tranplant.

用1／2MS培养基萌发花生种子，9-10d后，从无菌花生苗上切取幼嫩叶片中部为外植体。2500Lux光照和27±1℃条件下，在诱芽培养基(MS+BA3mg／L+NAA0.8mg／L+AgNO_32mg／L十Gln 6mg／L)培养12-14d即可观察到明显芽点或瘤状突起，较前人报道的培养时间大大缩短了，4w后芽点进一步发育成丛生芽，芽诱导率达90.2％，每个外植体平均产9个丛尘芽，然后转至培养基MS+BA3 mg／L+AgNO_32 mg／L上诱导芽的伸长，3-4w后可长至3-4cm，切下带有2-3片叶片的幼芽移至生根培养基(MS+NAA0.8mg／L+AgNO_32mg／L)，1w后切口处可见白色不定根形成。

The results showed that there were some differences in bud proliferation, rooting and vitrification among different genotypes.

结果表明：在芽苗增殖率、玻璃化程度以及生根率方面，品种之间存在着不同程度的差异。

There's no doubt about it, broadband is well and truly here to stay.

但毫无疑问的，是宽带，并真正落地生根。

The hydrolysates of five proteins materials,namely fish meal,meat and bone meal,soybean meal,rapeseed meal and wheal gluten meal,were prepared with alcalase and their root-inhibiting activity to Indian dendranthema, Dendranthema indicum Des Moul was measured in Petri dish at different concentrations,i.e.0,0.5,1,2,5 mg/mL.

以鱼粉、肉骨粉、豆粕、菜籽粕及芡粉等几种天然蛋白原料为底物，以碱性蛋白酶为水解酶制备出天然蛋白原料的水解物，用培养皿生物分析法检测不同蛋白原料水解物在不同浓度(0.5、1、2、5 mg/mL)条件下对杂草野菊种子的生根抑制活性。

Anyway, you people knew it came to the root of this Imperial City, and take root, sprout, arch territories and inadvertently stuck Nennen head, encouraged by the wind, so shake the, first look at this it seems strange the world, and then is quite a pretty body, looked at the foot of the sky, then looked again to see behind the walls, the cheeky smile, save enough effort and craned upward like branches.

反正，你在人们的不觉间就来到了这个皇城根下，而且生根、发芽、拱土并不经意地探出嫩嫩的头颅，在风的鼓动下，左右摇动着，先是看看这个似乎陌生的世界，然后又是挺了挺身子，看了看脚下又望了望天空，再看看身后的城墙，面露着微笑，攒足了劲似的向上伸着枝干。
