We presumed that the term of Y-linked inheritance cannot confuse with that of sex-limited inheritance, and that though the sex-limited factor and the sex-influenced inheritance gene are both located on autosome with some distance, but they are still different.

对现行的遗传学教材中存在的专业术语同名异义现象进行探研，针对Y连锁遗传、限性遗传、从性遗传、单倍体、多倍性和累加作用等专业术语存在的表达不清，相互矛盾，同名异义等问题，进行分析探讨，并提出Y连锁遗传不能与限性遗传相混淆，限性遗传和从性遗传的基因是位于常染色体上，但二者存在区别。

The results showed the autotetraploid and triploid cultivars had lower cold resistance than that of diploid under the condition of 12℃ temperature and 1000Lx. With the increase of stress time, the SOD and POD activities of three ploidy cultivars were gradually increased.

低温胁迫对不同倍性西瓜叶片膜脂过氧化及保护酶的影响：通过对蜜枚西瓜幼苗进行低温弱光处理（12℃，光强为10001x，光/暗处理时间为14h/10h）的试验结果表明，在没有冷诱导时M4x、M3x的耐冷性不如M2x。

Autotetraploids from diploidy leaves of Paulownia elongata on the double layer MS media supplemented with 0.1 mg/L NAA and 15 mg/L BA(optimal organogenetic medium to the leaves of diploidy seedlings) with different colchicines concentrations were induced,chromosome numbering of the plant root tip cells and DNA content analysis of the leaf single cell were used to analyse the autotetra ploids.

在含不同浓度秋水仙素的MS+0.1mg/L NAA+15mg/L BA双层培养基上进行兰考泡桐四倍体植株诱导试验，并通过变异植株根尖细胞染色体观察和叶片单细胞DNA含量测定进行倍性分析。

Aneuploidy is that cells or individuals possess abnormal chromosome number resulted by nondisjunction during cell division .

非整倍体指染色体分离异常所导致的染色体数目非整倍性改变所得到的细胞与个体。

Chromosome number also gives an indication of polyploidy, where numbers vary by exact multiples between related species.

当多倍性现象发生时，物种的染色体数目是原来的整数倍。

Genetic diversity in 12 populations of apomictic Eulaliopsis binata was evaluated by morphological observation and RAPD analyse ,as a result, 12 populations of E.binata were divided into different types.

通过分析龙须草核型和观察花粉母细胞减数分裂过程中染色体行为与变异，判断其倍性水平和多倍体类型。

Firstly, an invasive species must be invasive enough in itself or has some biological distinction, such as quantitative and qualitative differences in the genome, or patterns of recombination. Secondly, to invade successfully, a new environment for an invasive species must be invasible, and this we may call the ecological basis of invasion. An invasive species may need to establish new interactions with other species, especially those mutualistic relations such as animal related pollination, seed dispersal by animals, mycorrhizal fungi, and symbioses between plants and nitrogen fixing bacteria.

首先从其自身来说，需要有足够的入侵性，这可以认为是入侵种的生物学基础，可能表现为具有多倍性、一定的遗传变异、杂合性或表型可塑性，以及不同的交配系统等；其次一个物种的入侵成功还取决于入侵生境的可入侵性，这可以认为是入侵种的生态学基础，而新的种间关系的形成，尤其是入侵种与其他种类的互惠共生关系的建成是关键。

Lycopene content of 33 watermelons materials involved in different flesh color and ploid were determinated by Spectrophotometry in this experiment,the results showed that: lycopene content of the white flesh of watermelon was lowest,the highest content was dark red flesh,among white flesh,orange flesh,golden yellow flesh,pink flesh,red and dark red flesh of watermelon material,There was a positive correlation between lycopene content and flesh color.

采用分光光度法对33个西瓜材料进行茄红素含量的测定，材料涉及不同的瓤色和倍性。结果表明：在白瓤、橙黄瓤、金黄瓤、粉红瓤、红瓤和深红瓤的西瓜材料之间，白瓤西瓜茄红素含量最低，深红瓤西瓜含量最高，茄红素的含量与瓤色大致成正相关。其中深红瓤二倍体西瓜材料中S292、VS8-44的茄红素含量比较高，分别为6.372 mg/100g鲜重和6.350 mg/100g鲜重，三倍体材料中最高的是VS6-19，茄红素含量为6.684 mg/100g鲜重。

However, out of the 392 counted cells, no ploidy variated cell was found in the suspension used for the isolation of somatic protoplasts, all of them were diploid with 18 chromosomes.
