| 1. | Such a range of variation is termed a cline .
这样一个变异区域称为梯度变异。 |
| 2. | Two main types can be distinguished: ecoclines(clines along an ecological gradient) .
可以区分两个主要类型，即生态梯度变异（即沿着生态梯度出现的梯度变异）和另一种。 |
| 3. | The clinal variations of at least some physiological characters does not reflect unevenness at the subspecies boundaries .
至少有一些生理性状的梯度变异反映不出亚种边界的不齐性。 |
| 4. | This simple method gives only an indication of the intensity of selection responsible for the inception and maintenance of clinal variation .
这个简单方法只能说明对梯度变异开始和保持起决定作用的强度。 |
| 5. | The cline is considered the probable result of geographic trends in precipitation, temperature, and perhaps also photoperiod .
人们认为这种梯度变异可能是降水量，温度也许还有光周期等地理趋势造成的结果。 |
| 6. | The observed clinal variation in the frequency of serotinous cones may be described as a fairly regular decrease in all directions .
所观察到的晚熟球果的频率梯度变异可描述如下：向四周相当有规律地渐次减少。 |
| 7. | Varieties of flowering colors present cline . specially , variations of flowering colors within puer population are many and varied . longs and widths of perianths as well as longs of stamens are continuous variation of quantitative characters
结果表明：居群内各种形态性状都具有丰富的多态性，居群间具有明显的多型性；花色呈梯度变异，特别是普洱居群花色变异式样最丰富；花被片的长与宽和雄蕊的长度是数量性状的连续变异。 |
