叶顶芽

Genetic diversities were evaluated and compared at three levels of morphology(i.e., apical bud, leaf, seed and cupule for nine populations), allozyme and DNAs(AFLP analysis on four populations) in order to determine core germplasm of Q.

测定了共计9个群体的当年生枝的顶芽、叶、坚果、壳斗的表型多样性、9个群体的等位酶多样性、其中4个群体的DNA多样性，并对3个不同层次的遗传多样性研究进行了比较和评价。

Flowers from terminal buds; new leafy shoots from lateral buds, i.e., from axils of leaves of previous season; indumentum without flattened setae.

来自顶芽的花；来自侧芽的新叶状枝，即，根据以前的季节的叶的腋；没有使变平的刚毛的毛被。

Bud, leaf and leafstalk were cultured on different cultural conditions.

愈伤组织培养作了初步的探索，以不同的培养条件，利用连钱草的顶芽、叶、叶柄为外植体，研究了连钱草愈伤组织的培养。

Corm An organ of perennation and vegetative reproduction, consisting of a short erect fleshy swollen underground stem, usually broader than high and covered with membranous scales. It stores food material in the stem and bears buds in the axils of the scalelike leaf remains of the previous years ' growth.

球茎：球形或扁球形短而肥大的地下茎，节和节间明显，节上有退化的鳞片状叶和腋芽，顶端有一个显著的顶芽，茎内储藏着大量的营养物质，有繁殖作用。

The height of terminal buds, leave area and induction of adventitious roots of Ginkgo biloba were studied by adding of different concentration rare earth [La(NO3)3] in mediums of MS0 and 1/2 MS+0.5 mg/L IBA.

以银杏成熟胚诱导的无菌苗茎段为外植体，探討稀土[La(NO3)3]对其茎段顶芽高度、叶面积及芽苗不定根发生的影响。

H+ efflux and Fe3+ reduced substances release by the roots were inhibited by removing chlorotic leaves and buds caused by Fe deficiency, and progressively increased as they sprouted again.

摘除缺铁失绿的新叶和顶芽，抑制根系分泌H+和Fe3+还原物；但随着新叶的重新长出，根系分泌H+和Fe3+还原物的速率逐渐提高。

Stem nodes swollen. Stipules interpetiolar, sheathing terminal bud, caducous. Leaves simple, opposite or distichous, petiolate; leaf blade leathery, usually glabrous, margin entire, serrulate near apex, or completely serrulate.

茎节膨大。托叶在叶柄间，具顶芽鞘，早落；单叶，相反或，具叶柄；革质的叶片，通常无毛，边缘全缘，有细锯齿近先端，完全有细锯齿的或。

Trees evergreen; trunk monopodial, straight; branches nearly whorled; branchlets ridged and grooved, with each leaf borne on a persistent, peglike base; short branchlets absent; winter buds ovoid, conical, or subglobose, resinous or not, scales on terminal buds recurved or not, persistent at base of branchlets.

常绿乔木树干单轴分枝，直；分枝差不多轮生；小枝具脊和凹槽，有每叶生于一持久，钉状基础；短小枝无；卵球形，圆锥状的冬芽，或近球形，与否树脂，由顶芽开出的鳞片与否，宿存在基部的小枝。

The net photosynthesizes of different leaves drops rapidly when there is more than 20 piece of leaves,you may cut the terminal bud in production for the promotion underground portion growth.

不同叶位的净光合速率，当大于20片叶时下降较迅速，生产上可剪去顶芽，促进地下部分生长。

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。
