球茎

Terrestrial orchids may be rhizomatous or form corms or tubers.

陆生兰科植物可能是根茎或者形成球茎或块根。

Hot desert vegetation includes thorny shrubs, ephemeral annuals, underground corms and bulbs, and succulents, such as cacti.

植被 热荒漠的植被包括多刺的灌木、一年生的短命植物、地下的球茎、鳞茎和肉质植物如仙人掌。

The results showed that: a great quantity of compacted callus were induced on the MS medium supplemented with 6-BA and a large amounts of corms and young seedlings were differentiated on the differentiation medium, but plenty of loosened callus on the MS medium supplemented with 2,4-D and limited young seedlings on the differentiation medium.

结果表明：在附加6-BA的MS培养基上，外植体可诱导出大量的致密愈伤组织，而且致密愈伤组织在分化培养基中能分化产生大量圆球茎和幼苗；而在附加2，4-D的MS培养基中，外植体被诱导出疏松愈伤组织，在随后的分化培养基上只能产生数量有限的幼苗。

A perennial plant, such as a crocus or tulip, propagated by buds on underground bulbs, tubers, or corms.

地下芽植物一种通过地下鳞茎、块茎或球茎上的芽繁殖的多年生植物，如藏红花或郁金香

The research aimed to study the propagation and differentiation of PLB of Cymbidium hybridum×faberi.

［目的］对杂交兰原球茎的增殖及分化进行研究。

Anatomy study on the protocorm-like bodies formation and development of Cymbidium hybridium was conducted.

以大花蕙兰类原球茎发生发育不同阶段的培养物为试材，采用石蜡切片法对其进行组织学研究。

Segments produced clusters of somatic embryos from embryogenic calli or directly from root apical meristems , and that also can convert into bud directly in the different tissue culture conditions. Modified media B5 with 1.0 mg.L-1 2,4 - D and 3.0mg.L~1 6-BA is suit to induce calli, and 0.5 mg.L-1 NAA is fit for somatic embryos inducement from calli. 6-BA encreased direct somatic embryogenesis on root tip distinctly,but NAA is retard it. NAA also prolong the time of root-tip convert into bud directly.

在改良B_5(微量元素为原来的1／3)中加入1.0mg.L~(-1)2，4—D和3.0mg.L~(-1)6-BA对离体根尖的愈伤组织诱导较为合适，0.5mg.L~(-1)NAA有利于从愈伤组织上产生体细胞胚；6-BA明显促进离体根尖直接产生类原球茎，而NAA则有阻碍作用；同时NAA的存在也使离体根尖直接成芽的时间延长。

All parts of plant are highly toxic; bulb pounded and used as a fly poison; sometimes placed in subfamily Melanthiaceae.

该植物的各个部分都具有高毒性；球茎被捣碎用来制作苍蝇药。

These cheerful yellow and white harbingers of spring, aka daffodils and jonquils, are actually mildly toxic if the bulbs are eaten in large quantities (Narcissus pseudonarcissus is shown).

黄白两色相间的水仙花被视为春的使者，又叫长寿花，实际上如果较大量地食用其球茎，会有温和的毒性。

Contractile roots : they pull bulbs or corms of monocots , such as hyacinth and lily , and some taproots , such as dandelion , deeper in the soil through expanding radially and contracting longitudinally.

收缩根 ：他们把灯泡或球茎单子叶植物在这样的风信子和百合花，有的主根，如蒲公英，纵向放射状和承包更深的土壤中，通过扩大。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
