种子

And Hedysarum leave and (2) correlation of their responses with seed size.

种子埋得越深，种子的萌发率和出苗率越低，更多的种子受胁迫休眠保存在土壤中作为种子库。

I planted seeds of the Nierembergia variety "Blue Mountain" that is available from Park Seed Co. Seeds of the "White Robe" and "Purple Robe" varieties are available from Stokes Seeds.

我种的种子在Nierembergia品种&蓝山&，也就是可以从公园种子有限公司种子的&白色长袍&和&紫色长袍&品种可从斯托克斯种子。

Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

Conversely the seeds had the longest mean length of incubation time and germination peak value when pollinated every day.4 The planting date had effects on yield and quality of carrot seeds from different seed umbels and poisons of seed disc, also had effects on the growth and development of carrot steckling.

不同授粉时期对种子产量、千粒重、发芽率、发芽势的影响不显著，仅对种子的平均发芽天数、发芽高峰日分别存在显著、极显著影响，且&每日授粉&的种子平均发芽天数及发芽高峰日最长，&隔1日授粉&的种子平均发芽天数及发芽高峰日最短。

The results showed that the seed germination rate decreased gradually as the NaCl concentration increased .The seed germination rate and imbibition rate was lowest when the seeds were treated with 200 mmol·L~(-1)NaCl; the recovery rate of ungerminated seeds in 150 and 200 mmol·L~(-1)NaCl had no significant difference with the control and it was more higher than the seeds in100 mmol·L~(-1)NaCl.

的种子，逐日测定萌发率、吸胀率；5 d、10 d后测定种皮和种胚的Na~+、K~+含量；培养15 d后，将含有NaCl的营养液中未萌发的种子分别转入1/4 Hoagland营养液继续培养，测定解除盐胁迫后种子萌发的恢复率；以探索不同浓度的NaCl处理对海滨木槿种子萌发及其种皮和胚的Na~+、K~+含量的影响。

These results suggested that higher concentration of NaCl could cause the seed dormancy and accelerate the germination of ungerminated seeds. Perhaps there was a mechanism that the seed coat or embryo could prevent Na~+ from entering into the embryo so as to keep higher K~+ and lower Na~+/K~+ in the embryo. And it might be one of the physical mechanisms that the seed of Hibiscus hamabo Sieb.et Zucc. could resist high salinity stress. In addition, the annual seedlings of Hibiscus hamabo Sieb.et Zucc.

上述结果表明：高浓度的盐可以诱导海滨木槿种子休眠并促进盐胁迫解除后种子的萌发，这种机制可以使之避开不良的萌发条件，等到降雨使土壤溶液浓度降低再萌发，这是盐生植物的种子适应盐渍生境的一种有效方式；海滨木槿的种皮有阻挡Na~+进入胚的作用或胚具有某种拒Na~+的机制，使胚保持较高含量的K~+和较低的Na~+/K~+，这可能是海滨木槿种子耐盐的主要生理原因之一。

Put the seeds into wettish sand under temperature of 25,20,15,10,5 ℃,observe the shape changing of embryo and measure its length every other 10 days.

在25，20，15，10，5℃下层积处理明党参种子，每隔10 d观察种子胚的形态变化，并测定种子的胚长和种子霉烂率。

In order to verify the possibility of lyophilization technology used for the drying treatment of wheat seed, different drying modes under lyophilizing, vacuuming and hot air was employed and compared in this research.

为了探索真空冷冻干燥技术用于小麦种子干燥处理的可能性，采用真空冷冻干燥、真空干燥和热风干燥 3种方式对小麦种子进行干燥处理，在不同环境温度和压力下，研究种子中温度-时间分布曲线，并通过分析复水率、出芽率和幼苗生长情况进一步研究了这 3种干燥方法对小麦种子生物活性的影响。

In order to explain clearly the variation status of embryo from tetrapoid Robinia pseudoacacia and fully use the variation resource initiated in the sexual reproduction of TRP in the further improvement of TRP, the classification and vitalities of seed embryos from tetraploid Robinia pseudoacacia were studied. The main results are as follow. According to the cotyledon number, color and plumpness, the seed embryos of TRP could be divided into 5 types: YVT (yellow, very replete,2 cotyledons), YMT( yellow, more replete,3 cotyledons ), YRF ( yellow, replete,4 cotyledons ), GNT ( green, no-replete, 2 cotyledons ) and WNT ( white, no-replete, 2 cotyledons ).

为了阐明刺槐同源四倍体种子胚变异状况及充分利用刺槐同源四倍体有性过程创造的变异资源对四倍体刺槐进行遗传改良，研究了刺槐同源四倍体种子胚类型及其生活力特征，主要结论如下：刺槐同源四倍体种子胚按照子叶数量、颜色及饱满程度，可以划分出5个类型：黄二、黄三、黄四、绿二及白二，所有类型种子胚混合平均单胚重量接近二倍体的1/2。

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