鳞茎

The characteristic of nutrient absorption and distribution in lily (Longiflrorum and Asiatic hybrids 'Evening Star') were investigated during the bulblet swelling development, the circumference of which is 4～6cm.

本文以周径为4～6cm的'耀眼'百合的小鳞茎为试材，研究了常规栽培条件下百合小鳞茎膨大发育过程中养分的吸收和分配规律。

The research aimed to study the effects of methy jasmonate on bulblet and scale leaf growth of Lilium 'Mona' in vitro, to solve vigorous growth of scale leaves during tissue culture of bulblets in Asiatic Lilium.

［目的］研究茉莉酸甲酯对组培"Mona"百合鳞茎及鳞片叶生长的影响，以解决亚洲系统百合在试管鳞茎培养过程中鳞片生长过旺的问题。

Scale cutting method combined with different growth medias was used to evaluate the effect of slice number per bulb, bulb scale development stage, water content and cutting time on the proliferation ability of the bulblet formation with 10 cultivars from domestic and abroad.

以国内外10个朱顶红品种为材料，研究了不同品种、鳞茎切块数量、鳞茎年龄、基质种类、基质含水量、切块时间等因素对朱顶红繁殖能力的影响。

The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

结果显示；低浓度的NAA0.1~02mgL^(-1有利于根的诱导；生根率均达100%；大量元素1/4MS处理更适合试管苗的生根和小鳞茎形成；"IBA+AC"处理最佳组合是2.0mgL^(-1) IBA+0.1%AC；鳞茎直径≥9mm的试管苗去顶4℃低温冷藏4周；移栽后喷施1/2MS营养液；长势最好；成活率达到100%。

Application of MeJA is the efficient way for overcoming the problem of subculturing overelaborate during the tissue culture of Lilium 'Mona', and 1.0 μmol/L MeJA is suitable for promoting bulblet growth and inhibiting scale leaf growth of Lilium 'Mona'.

结论］在"Mona"百合试管鳞茎培养的培养基中加入1.0μmol/L的茉莉酸甲酯时即可抑制鳞片叶生长也可促进鳞茎膨大生长。

Result The scale leaf formation was inhibited by MeJA, the higher the concentration of MeJA the more efficient for restraining scale leaf growth. 100.0% of bulblet formation was obtained in the treatment of 1.0 μmol/L MeJA, but the scale leaf growth was significantly lower than control. 3.0 μmol/L MeJA had the inhibitory effect to both the bulblets and the scale leaves.

结果］茉莉酸甲酯对"Mona"试管百合鳞片叶生长有抑制作用，浓度越高其效果越明显；当茉莉酸甲酯浓度为1.0μmol/L时，鳞片叶发生率(87.9%)明显低于对照(100.0%)，但鳞茎分化和生长也显著好于对照；但茉莉酸甲酯浓度超过3.0μmol/L时，不仅对鳞片叶而且对鳞茎生长也有抑制效果。

The results showed that middle layer scale crosscut into 6 sections had the highest propagation coefficient.

结果表明：取中层鳞片、每片横切 6段的繁殖系数最高，基部鳞片结鳞茎数最多，且鳞茎发生最早。

Bulbs laxly clustered; bulb tunic membranous, laciniate; pedicels 1--1.5 × as long as perianth; perianth segments elliptic to ovate, 6--7 × 3--4 mm; broadened base of inner filaments narrowly ovate

鳞茎稀松的簇生；鳞茎皮膜质，条裂；花梗1 --1.5 *倍于花被；花被片椭圆的到卵形， 6--7 * 3--4 毫米；扩大内轮花丝狭卵形的基部 52 ALLIUM caespitosum 疏生韭

Bulbs with (1 or)2 or 3 fleshy, farinaceous scales, often covered with a translucent tunic, sometimes also with numerous small bulbels. Stem erect, simple, leafy.

鳞茎具(1或) 2或3肉质的，粉质鳞片，通常为一半透明鳞茎皮所覆盖，茎直立，单，多叶。

However, ramets didn't survive in high concentration of Pb but grew in healthy habitat in phalanx pattern and the ortet grew in high concentration

高浓度CO：从克隆体系整体上使鳞茎生物量分配比例增加，而减少了叶的比'例。在子株中鳞茎比例不仅显

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
