鳞茎

The results indicated that nutrition element stored in bulblet was consumed for new leaves and stem growing before plantlet stage.

结果表明，百合小鳞茎在苗期以前，主要以消耗鳞茎中的养分为主；苗期后对营养元素的吸收量逐渐增大。

Using bulblet and scale segments of Asiatic Lilium 'Mona' in vitro, the effects of MeJA on the growth of scale leaves were investigated.

方法］以亚洲型"Mona"百合试管鳞茎、鳞片的切片为外植体，研究茉莉酸甲酯对鳞片叶及鳞茎生长的影响。

Mean bulblet diameter was 5-10 mm made the ratio was 97~100%.Bulb with leaves and roots can make the ratio higher.

试管鳞茎的直径为5～10mm时，移栽成活率高达97％～100％，并且鳞茎带叶和根有助于移栽成活。

The differentiation ability for different parts of bulblet leaves was studied,and the results showed that the apical part of leaves did not regenerate,however,mass shoot regeneration occurred from the leaf base,occasionally from the middle part.

通过对再生苗叶片不同部位的再分化实验，比较得出小鳞茎叶的叶片基部分化能力非常强，而叶片上部基本不分化，鳞茎叶基部是建立高频快速再生体系的首选材料。

Bulb narrowly ovoid or cylindric; tunic black-brown, scarious; bulbels many, with several fleshy scales and hard tunics.

鳞茎狭卵球形或圆筒状；鳞茎皮黑棕色，干膜质；珠芽很多，带有几个肉的鳞片和硬鳞茎皮。

The small bulbs induced were full and the shapes of them were regular. The explants incubating in other seasons were not suitable. By comparison different incision methods, we found it' was better taking stem plate carrying bulb leaves as explants than any other treatments.

通过对不同季节的水仙鳞茎外植体进行组培观察，发现8月份至次年5月份接种的水仙外植体，小鳞茎的诱导率几乎达到100%；并且，小鳞茎比较饱满，形态比较规则，其它时间接种的水仙外植体的组培效果均不理想。

In order to breed new germplasm for Narcissus tazetta,the bulb of Narcissus tazetta is used as explants.The adventitious buds is induced in MS media with hormone combination.γ-ray irradiation treatment of Narcissus tazetta combined with tissue culture is studied.Three materials,including the bulb basal plate tissues inoculated for 7 days,tissues transferred in fresh differentiation culture medium for three days after inoculated for 25 days,and small bulbs in vitro,are studied.

以带鳞片叶的鳞茎盘为外植体，接种在添加激素的MS培养基上，通过激素组合筛选合适的培养基获得不定芽，同时对在预分化培养基上接种7D的外植体、接种25D后转接到分化培养基上3D的外植体、诱导产生的试管小鳞茎进行辐照诱变处理，研究了60COΓ射线对中国水仙丛生芽分化以及小鳞茎生长的影响。

In cider to breed new gern1asm for Narcissus tazetta, the bulb of Narcissus tazetta is used as explants. The adventitious buds is induced in MS media with hormone combination.γ-ray irradiation treatment of Narcissus tazetta combined with tissue culture is studied. Three materials, including the bulb basal plate tissues inoculated for 7 days, tissues transferred in fresh differentiation culture medium for three days after inoculated for 25 days, and small bulbs in tarn, are studied.

以带鳞片叶的鳞茎盘为外植体，接种在添加激素的MS培养基上，通过激素组合筛选合适的培养基获得不定芽，同时对在预分化培养基上接种7d的外植体、接种25d后转接到分化培养基上3d的外植体、诱导产生的试管小鳞茎进行辐照诱变处理，研究了60Coγ射线对中国水仙丛生芽分化以及小鳞茎生长的影响。

The bulb scales had a higher induction rate of 89.3% to 93.3%, better quality and lower decay rate and the best rooting, in which single-scale reproduction coefficient reached 1.14 to 1.19 when cutting in soil from original environment and peat and pearlite (1:1) as medium under the condition of 25℃ and dark, followed by cutting in peat and sand (2:1) and peat and vermiculite and perlite (1:1:1). There were the highest single-scale reproduction coefficient (1.38) when cutting in sand, but the induction rate was lowest (58.7%). The bulb scales was easy to rot and unfit for use in peat.

以原生土、草炭＋珍珠岩(1：1)这2种基质最好，诱导率达89.3%93.3%，平均每鳞片繁殖小鳞茎数较高，达1.14~1.19个，产生的小鳞茎质量也较好，而且鳞片腐烂率低，生根效果也最好；草炭+河沙(2：1)及草炭+珍珠岩+蛭石(1：1：1)的扦插效果仅次于草炭+珍珠岩(1：1)；河沙扦插鳞片时，平均每鳞片繁殖小鳞茎数最高，达1.38个，但诱导率最低(58.7%)，易造成鳞片干萎，草炭则易造成鳞片大量腐烂，均不宜使用。

Bulb ovoid-globose or globose, 5--8 mm in diam.; tunic dark brown, subleathery; bulbels several, within tunic, narrowly ovoid.

直径的鳞茎卵球状球形的或球状，5-8毫米；鳞茎皮暗褐色，近革质；珠芽几，在鳞茎皮内，狭卵球形。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
