With Zhonghuang 35 as tested materials, the seed germination experiments of soybean were carried out by using 0.01, 0.10, 1.00 and 10.00 mg/L NAA. After culture for 7 d, the germination rates and the lengths of plumular axis, radicle as well as germ of soybean seeds were measured to compare the effects of NAA with different concn. on the plumular axis length and hypocotyls-radicle ratio when the soybean seeds germinated.

方法］以中黄35为供试材料，采用不同的NAA浓度(0.01、0.10、1.00、10.00 mg/L)对黄豆种子进行萌发培养试验，培养7 d后分别测量黄豆种子的萌发率以及胚轴、胚根和胚芽的长度，比较不同浓度的NAA对黄豆种子萌发时的胚轴长、胚轴胚根比的影响。

The results of studying the effects of several plant growth regulating substances on pollen germination and tube growth in pear (Pyrus serotina Rhed.) by cultivating pollens in liquid media showed that GA3,TRIA,IAA and 2,4D stimulated pollen germination and tube growth when pollen was cultivated in their lower concentration media.

采用花粉液体培养法研究了植物生长调节物质对梨花粉萌发和花粉管生长的影响，结果表明：较低浓度的赤霉素、三十烷醇、吲哚乙酸及2，4-D均能促进花粉萌发和花粉管生长，而超过一定浓度时却起抑制作用，最适宜于花粉萌发和花粉管生长的赤霉素浓度为50～300mg/L，三十烷醇为3～100mg/L，吲哚乙酸为5～25mg/L，2，4-D为5～10mg/L。

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。

The strategies for adaptation of halophytes to saline and arid environments during seed germination stage:(1) high salinity and temperature induce seeds to remain dormancy. Compared with Haloxylon persicum, more viable ungerminated seeds of H. ammodendron and S. physophora submerged in 700 mmol.L-1 NaCl can germinate rapidly when environmental conditions are favorable.

盐生植物种子萌发期间适应盐渍和干旱环境的策略表现在：(1)高盐和高温诱导种子休眠。700 mmol·L~(-1) NaCl浸泡后，与白梭梭相比，梭梭和囊果碱蓬有更多的未萌发的种子能够保持活力，在清水中快速萌发。

According to field observations and inoculation experiment,the diseasedplants bearing numerous perithecia left in the soil during harvest probably serveas the main source of infection .

小麦秆枯病菌子囊孢子必需要有小麦组织的刺激始能萌发。在缺乏刺激物时，萌发率一般在1%以下，加入刺激物后，萌发率可以提高数十倍。

The seeds, tubers and corms of the weeds mainly distributed in the 0- 15 cm depth paddy soil, and mostly executed veget

种子萌发主要在土壤表层，块茎萌发在0～15cm土层内；土壤含水量饱和至薄水层最有利于萌发。

Exam ination ofin vitrogerm ination of these 2n pollen grains revealed that the ir germ ination percentage and pollen tube elongation rate were w ith in the norm a...

初步观察了2n花粉离体萌发状况，其萌发率与花粉管伸长速度较为正常，但萌发启动比单倍性花粉慢。

The conidial germination need some special nutrients. The best carbohydrates and nitrogen for conidial germination are 1% saccharose and 1% glycin; the proper temperature was 20-30℃ and the optimal temperature was 25℃; the optimal pH was 5-6; the light had no obvious promotion effect on spore germination. The spores could not germinate above 52℃ for 10 min.
