Gall An abnormal outgrowth or swelling on a root, stem, or leaf in response to attack by a parasite or to invasion by a symbiont.

瘿：当植物体受到寄生植物或共生体的入侵时，其根、茎或叶上会生长出一种变态产物或凸出物，即为瘿。

"The photosynthetic and supportive cells tend to be organized linearly, but a thallus lacks such differentiated specialized structures as stem, leaves, and conducting tissue."

那些可进行光合作用和所维生的细胞呈线形结构，但原植体则无根、茎、叶的分化，无输导组织。

"The photosynthetic and supportive cells tend to be organized linearly, but a thallus lack s such differentiated specialized structures as stem, leaves, and conducting tissue."

那些可进行光合作用和所维生的细胞呈线形结构，但原植体则无根、茎、叶的分化，无输导组织。

Leaves radical from vegetative stem, solitary from flowering stems, curvinerved.

It suggested that Cynodon dactylon had strong toleration to flooding by prolonging stem, changing leaf shape and reducing biomass.

实验表明狗牙根繁殖体通过延长茎长、改变叶形和减少生物量等方式对水淹显示出较强的耐受能力。

Different plant hormones and their different concentration ratios have different effects on the callus of Halenia elliptica D.

结论不同培养条件对椭圆叶花锚愈伤组织的诱导有不同的影响，其中以无菌苗的茎段为外殖体易形成愈伤组织。

Stems succulent. Leaves opposite, petiolate; stipules deciduous, intrapetiolar, connate, membranous; leaf blade 3-veined, usually symmetric, margin serrate-dentate; cystoliths linear.

茎肉质的。叶对生，具叶柄；托叶脱落，叶柄内，合生，膜；叶片3脉，通常对称，边缘有锯齿有齿；钟乳体线。

At least basal leaves dentate, serrate, or pinnatifid; median filaments free; stems glabrous or with straight trichomes.

至少基生叶具牙齿，使成锯齿波，或羽状半裂；中间的花丝离生；茎无毛的或具直的毛状体。

Stems of Ipomoea batatasLam in vitro were cultured on MS rhizogenic base medium. ifferent combinations of CO2 concentration and photosynthetic photo flux density in microenvironment were controlled and recorded by special system. The plantlets getting the highest net photosynthetic rate were treated by the combination of (Ci=8 720 μmol mol-1,PPFD=250 μ mol m-2 s-1). Then, the plantlets had been further cultured for 21 d in such microenvironment.

以新兴蔬菜叶用甘薯组织培养苗的茎节段作为外植体，用MS低糖、无激素培养基进行生根培养，设置不同的CO2浓度和光合光量子通量密度对组培植株进行环境调控处理，获得小植株净光合速率最高的处理组合=8 720 μmol mol-1， 250 μmol m-2 s-1），并在此组合下继续培养21 d。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
