无胚的

Seeds winged or with a fleshy aril or sarcotesta wholly or partly covering seed; endosperm fleshy or usually absent.

All the contents of Extractable heavy metal like Pb, Cu, Zn and Cd in limestone slagged wasteland are higher than those in contrapositive soil nearby. The slag filtrate has no effect on seed germination rate of Mung beans, Broad beans and Corns but restrains their germination vigor and protraction of hypocotyls with root restraint rate exceeding 30-50%; While it has an apparent effect on germination rate and germination vigor of sensitive seeds like Beans with P=0.05. Simulate to plant the 4 different seeds in pot for a month, Test groups have a lower data in total leaf area, plant height and weight but a much higher content of protective materials like PRO and MDA in biochemical mensuration experiment compared with CK group.

石灰炉渣废弃地中Pb、Cu、Zn、Cd重金属有效态含量均高于临近对照土壤，其炉渣淋出液对绿豆、蚕豆、玉米3种植物种子发芽率无影响，但均抑制其发芽势和下胚轴伸长，根长抑制率达30%~50%以上，对敏感种子黄豆的发芽率、发芽势（4d）影响明显，摸拟盆栽一个月苗期，4种植物试验组在总叶面积、株高、生物量方面均低于对照组；生理生化测定，4种植物其体内抗逆性保护物质脯氨酸和膜过氧化产物丙二醛含量试验组均高于对照组。

Ovary inferior, stalked or sessile; ovules 2 or 3, pendulous from apex of placenta, usually flexuous or corrugate.

子房下位，柄或无梗；胚珠2或3，从胎座的先端下垂，通常曲折或皱。

Pistillate flowers: calyx as in staminate flowers, persistent; corolla 4- or 5-lobed, base tubular and often inflated; reduced stamens absent; ovary sessile or with short pedicel, 1-loculed; ovules 2, pendulous from apex; stigma thick, peltate, apex concave, sometimes slightly oblique.

Although high genetic diversity including variation of ploidy level, polyembryony and twin-embryonic phenomenon existed in the genus Coffea, there was less study on how about the apomixes in coffee.

咖啡属植物遗传类型丰富，具有多个倍性水平，偶见种子的多胚豆和双生苗现象，但是对于咖啡属植物中是否存在无融合生殖遗传特性，有关报道甚少，目前尚无无融合生殖材料选育的报道。

Male glomerules axillary, 1-1.5 cm in diam. Male flowers 5-merous; pedicel 4-5 mm; perianth lobes boat-shaped to elliptic, ca. 1 mm, glabrous or subglabrous, connate at base, often corniculate near apex; rudimentary ovule ellipsoid, ca.

腋生的雄性团伞花序，1-1.5厘米直径雄花5瓣；花梗4-5毫米；花被裂片舟状的到椭圆形，约1毫米，无毛或近无毛，在基部合生，经常具小角状突起的近先端；不发育胚珠椭圆形，约0.5毫米。

Female flowers: perianth tube adnate to ovary, mouth contracted, apex 3- or 4-toothed; staminodes absent; stigma sessile, discoid or peltate, long ciliate hairs along margin; ovule orthotropous.

雌花： 花被筒贴生于子房，口部收缩，顶3或4齿状；退化雄蕊无。柱头无柄，盘状的或者盾形，具长缘毛毛沿边缘；胚珠直生的。

Disk absent. Ovary ovoid, cylindrical, or bottle-shaped, glabrous or hairy, many loculed; ovules numerous per locule; styles as many as carpels (15-30), usually reflexed, persistent, radiating, in functionally female flower elongating after anthesis; rudimentary ovary in functionally male flower very small, with minute styles.

花盘无。子房卵球形，圆筒状的，或瓶形的，无毛或有毛的，很多室的；胚珠多数每室；花柱同数于心皮(15-30)，通常反折，宿存，辐射状，功能上的雌花花后延长；功能上的雄花不发育子房很小，具小的花柱。

Lodicules absent; ovary glabrous. Caryopsis obliquely obovate in side view; endosperm sometimes liquid.

鳞被无；子房无毛在边意见里斜倒卵形的Caryopsis；有时的胚乳液体。

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
