For drought tolerant genotypes, the relative value of proline content, SOD or CAT activity of plumule should be larger than 2.2, 0.8 and 0.8, respectively, while for drought sensitive ones, the relative value should be less than 1.5, 0.65 and 0.4, respectively.

渗透胁迫条件下胚芽鞘脯氨酸、CAT和SOD的T/CK值分别大于2.2、0.8和0.8为强抗旱性品种，而抗旱性弱的品种则分别小于1.5、0.65和0.4。

In conventional sexual hybridization of citrus, nucellar polyembryony, pollen/ovule sterility, genetic heterozygosity, wild sexual incompatibility of most citrus cultivars make it very time-consuming and low efficiency to improve fruit characters.

但是，由于柑橘类植物中存在的珠心胚现象、一些品种中的雌雄性败育、童期过长、远缘有性杂交不亲和等特点使通过传统的有性杂交方式进行品种改良进程缓慢，效率不高。

IN THE 14 years since the first genetically modified crops were planted commercially, their descendants, relatives and remixes have gone forth and multiplied like profitable, high-tech pondweed.

自转基因首次走向市场的14年中，它们的后代、类似品种以及杂交品种不断出现并增多如可获利的高科技水池草。

According to this paper, the use of P〓—IPT gene to improve wheat varieties that had the defect of leaf presenility was feasible. In this way, the potential yield of that wheat could be developed greatly and the new lines for wheat breeding could be produced.

根据本试验的研究结果，表明可以利用P〓-IPT基因对生产上有早衰缺陷的小麦品种进行遗传改良，以最大程度地发挥现存品种的生产潜力及为育种创造新种质。

To examine their function in progressional cell death, we analyzed the cell-death phenotype in cnx-1 and crt-1 mutants.

我们以分析此两基因突变品种上出现之突起透镜状细胞尸体的数量和野生型品种N2比较为方法，来检测它们在细胞死亡过程中的功能。

These results suggested that species differences must be considered for prolificacy individual selection.

本研究结果提示：绵羊多羔个体的选择有品种差异，应根据不同品种各自的多羔基因型进行选择。

Furthermore, the genetic relationship between the polymorphism of Prolactin and the prolificacy of Small Tail Han Sheep was explained.

结果表明： 5个绵羊品种在引物2的扩增产物中均存在单核苷酸多态性，其中只有多赛特羊未检测出DD型，而其余4个绵羊品种均检测出CC、CD和DD型。

Some of the liquid spills out through the capillary constantly with the rise of the temperature of the content. Wipe away the overflown liquid with a piece of filter paper at any time until the fluid does not overflow anymore. Remove the pycnometer from the water bath rapidly. Proceed as described under method (1), starting from the words "clean off any material on the outside with a piece of filter paper…".

取洁净、干燥并精密称定重量的比重瓶，装满供试品（温度应低于20°C或各品种项下规定的温度）后，插入中心有毛细孔的瓶塞，用滤纸将从塞孔溢出的液体擦干，置20°C（或各品种项下规定的温度）恒温水浴中，放置若干分钟，随着供试液温度的上升，过多的液体将不断从塞孔溢出，随时用滤纸将瓶塞顶端擦干，待液体不再由塞孔溢出，迅即将比重瓶自水浴中取出，照上述（1）法，自"再用滤纸将比重瓶的外面擦净"起，依法测定，即得。
