种子的

All seeds were collected from maples in my backyard in late October and early November. Since not all maples grow seeds and not all of the seed growers produce abundant number of seeds, we could only come up with the identified quantity.

所有的种子都是在10月底和11月初采自我后院种的枫树，由於不是每种都会结籽，而且也不是每种都有大量的种子，因此我只能提供个别所得的数量。

The natural distributing populations of the indigenous timber species--Cordia africana that grew in and around the area of Mizan Teferi in Ethiopia were investigated. Bulk seed samples were selected from ten phenotypically superior trees in different natural populations. They were evaluated through the performance of their half-sibs and especially examined for variability in seed morphometrics, seed germination, and seedling growth at nursery stage.

通过对埃塞俄比亚Mizan Teferi及周边地区生长的乡土用材树种--非洲破布木自然种群分布情况调查，筛选了10株生长表现型较好的优良母树，采集了大量的供试种子样品，并对其种子外部特征和在苗圃中的发芽率和种苗生长表现进行了观察和分析对比。

In the crosses of the autotetraploidy rices used as the females, some seeds could be got, but more seeds were obtained in these crosses by the special treatment that the DH solution was put into the caryopses before the pollination.

在以同源四倍体水稻为杂交母本的杂交组合中，可以获得一些实粒种子，但是，如果在授粉前利用DH溶液对同源四倍体水稻的去雄颖花进行处理后再授狼尾草的花粉粒则能获得更多的实粒种子。

The floristic components have character as following: geographic -al elements of species is relatively simple;there are more species of world distributi -on and tropical genera,and there have world blazon predestined relationship and tropical predestined relationship.Composite,standing grain,legumina have absolutely predominance make of the backbone of floristic.Seed plants are mainly made up of herbage plants.

种子植物区系成分具有以下特点：种的地理成分相对简单；表现出明显的亚热带特征，并具有热带向温带过渡的特点；菊科、禾本科、豆科占有绝对优势，构成植物区系的骨干；种子植物主要由草本植物组成，草本植物占绝对优势。

Both of them, to be codominant markers, can identify false hybrids not only from selfed seeds of male and female but also from foreign pollen and mechnical contamination.

两引物均能在父母本中扩出特异带，为共显性标一记，不仅能够鉴别杂交种中混杂的母本自交的种子和父本的种子，还可鉴别部分由于外来花粉或机械混杂等造成的假杂种。

Rhizoctonia cerealis was the most inhibited (89.3%) among the 11 species. A dry seed treatment of α-pyrone 0.2% WP at 0.5% controlled wheat root rot 61.6% and cotton damping-off 85.6% in the greenhouse; these re...

温室条件下用干种子量0.5%的0.2%α-吡喃酮WP拌种处理对小麦纹枯病的防治效果达61.6%，对棉花立枯病的防治效果达85.6%，较干种子量1%的40%多菌灵拌种处理防治效果分别提高了14.6%和17.9%。

If we don't manage to stop their spread in our fields, soon we'll be forced to buy our corn seed because our own won't work anymore?

如果我们不终止它们在我们的田地里的传播，用不了多久我们将被迫使购买玉米种子，因为我们自己的玉米种子无法再繁殖。

It is difficult to meet people that the methods of past identifications.

论文摘要：种子纯度在种子生产中的地位日益提高，以往的形态鉴定等方法难以满足人们的要求。

The status of Seed purity are increased in seed production .It is difficult to meet people that the methods of past identifications.

种子纯度在种子生产中的地位日益提高，以往的形态鉴定等方法难以满足人们的要求。

At 12% m.c. was also better than the lots at 10% or 11% m:c: A free-fall of soybean seed from different heights on to the cement floor resulted in greater loss in qualitythan when dropped on to the galvanized iron floor.

含水量为12%的种子比10%及11%都都要更好一些。黄豆种子从不同高度自由下落到水泥地上所造成的质量损失要比电镀铁板上的大。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
