These results indicated some differences from other investigated autopolyploid plants in autopolyploid watermelon. Autotriploid watermelon, in particular, showed unusual characters of genome structure and DNA methylation status, which may be closely associated with the oddploidy effect and the excellent traits present in triploid plants.

综上结果证明，西瓜同源多倍化过程中发生的遗传和表观遗传改变与已报导的一些植物的同源多倍化有所不同，特别是三倍体西瓜，其表现出独特的基因组结构及DNA甲基化状态变化特徵，而这可能与植物的奇倍性效应及三倍体西瓜优良性状的形成密切相关。

To breed grafting watermelon Zhuang Miao, terminal of promotion of farming ability of terminal of farming ability promotion and peaceful wave city is in county of peaceful 2005 sea jointly town of street of Ning Hai's head of a county undertook inside the grow seedlings canopy of Shao Xingyong of village of palace of empress or imperial concubine of the first rank " in mother " the card is compressed model matrix nutrition earthen bowl Ci Xi, summarize test result as follows now. Earthen bowl of nutrition of the compression that 1 experiment process suits grafting watermelon grow seedlings to use matrix has 6cm × 2.5cm or 5cm × 2.2cm, what this we choose is 6cm × 2.5cm, smooth squeezing ramming should make seedbed copy first when grow seedlings, seedbed upper berth lies between water to use deep plastic film, in order to prevent moisture leakage and root system next plunging into, make sure nutrient earthen bowl is even and bibulous, filmy all around left and right sides of tall 6cm of bed a low bank of earth between fields, avoid prediction of a person's luck in a given year of moisture side direction.

为了培育嫁接西瓜壮苗，2005年宁海县农技推广总站和宁波市农技推广总站共同在宁海县长街镇娘娘宫村邵兴永的育苗棚内进行了"中慈"牌压缩型基质营养钵(慈溪市中慈生态肥料有限公司生产)和常规塑料钵育苗对嫁接西瓜秧苗素质影响的对比试验，现将试验结果总结如下。1试验过程适合嫁接西瓜育苗用的压缩型基质营养钵有6cm×2.5cm或5cm×2.2cm，这次我们选用的是6cm×2.5cm，育苗时要先将苗床底整平压实，苗床上铺隔水用厚塑料薄膜，以防止水分渗漏和根系下扎，保证营养钵均匀吸水，薄膜四面床埂高6cm左右，防止水分侧向流失。

Do not eat watermelon, watermelon's sugar content is too high, and eat more easily induced gestational diabetes, and I seized the middle of the last half-eaten watermelon time, the results of urine has 3 +, the doctor suspected diabetes, the next day A post-mortem blood glucose, only fine

不要多吃西瓜，西瓜的含糖量太高了，吃多了容易诱发妊娠糖尿病的，我上次产检的时候吃过半个西瓜，结果尿糖有3个+，医生怀疑是糖尿病，第二天又抽血验血糖，才没事

In this study, the aged watermelon seeds were selected as material, soaked by different concentrations of salicylic acid, calcium nitrate and gibberellic acid (GA3), to study the effects on germination rate, related physiological and biochemical indexes of aged watermelon seeds. The results show that the activity of aged watermelon seeds was obviously increased after soaking, and the best treatment to promote germination was Ca(NO3)210mmol/L. Besides, conductivity and soluble sugar content of seeds lixivium, and MDA content of seeds were decreased obviously after treated by SA, Ca(NO3)2 and GA3, and SA treatment had the best obvious effects.

本试验以自然老化的西瓜种为试材，采用不同浓度的水杨酸、硝酸钙、赤霉素预浸种处理，研究其对老化西瓜种子萌发及相关生理生化指标的影响，结果表明：不同处理均可显著提高老化西瓜种子活力，以10mmol/L的Ca(NO3)2处理促进萌发的效果最为明显；不同处理均能明显降低种子浸出液电导率、可溶性糖含量及种子中丙二醛含量，以水杨酸的各处理效果最好。

The results showed that the main component of sugar in flesh tissue of both fruits of own-rooted and grafted watermelon fruit was sucrose and that in mesocarp tissue was hexose. The sugar content of the grafted watermelon fruit was lower than that in the own-rooted watermelon fruit.

结果表明：嫁接与自根西瓜果实的果肉组织均以积累蔗糖为主，果皮以积累已糖为主，嫁接西瓜果实的糖含量显著低於自根西瓜。

Don't ask me, I forgot totally about the what kind of melons is that already. Its appearance is like watermelon, however, its pulp is just like winter melon.

它西瓜不像西瓜，冬瓜不像冬瓜，有像西瓜外观的皮以及像西瓜籽子的白色籽子，也有像冬瓜的肉。

However, analysis of DNA methylation level indicated that the total DNA methylation levels were not significantly different between diploid and autotetraploid. Autotriploid showed a trend of low DNA methylation level. It implied that the alterations of DNA methylation levels were not linear with the autopolyploidy level in watermelon.

有趣地是，二倍体与四倍体西瓜相比DNA甲基化水准却未发生大规模的调整，而三倍体西瓜显示出较为明显的低DNA甲基化水准趋势，表明西瓜同源多倍化过程中其基因组DNA甲基化水准变化与其倍性不成线性关系。

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。

Big output, distribution period concentration and the improper storage bring about high rot rate,it seriously affects the quality,export and storage.At present,the problem of Watermelon storage has been unsolved,it affects the development of Watermelon.

但由于新疆地处边远，西瓜的产量大、销售期集中和贮运方法不当，致使其腐烂率很高，严重影响了西瓜的品质、外销和贮藏，目前西瓜的贮藏保鲜问题尚未解决，严重影响着西瓜产业的发展。

Then the waveband was divided into two parts to develop calibration model using partial least square method for soluble solids content to remove the effect of the skin and the results indicated that the measurement results was not be enhanced. However, the difference of calibration results in the wavelength of 650-950nm with the r of 0.949, the RMSEC of 0.292 for intact watermelon and with the r of 0.973 and the RMSEC of 0.214 for skin-peeled watermelon indicated that the influence of skin is not very serious and the intact watermelon spectra also can get satisfied calibration result. 5. Vis/NIR spectroscopy nondestructive detection needs high-energy light source, so differences of diffuse transmittance spectra with different light intensity (600W, 1000W) were detected and effects of light intensity on spectra and calibration results were compared.

针对西瓜果皮较厚的特点，对去皮西瓜与带皮西瓜进行对比试验研究，发现果皮对光谱的影响主要集中在可见光部分(650-750nm)，对可溶性固形物含量采用偏最小二乘法进行分段建模并没有有效消除果皮的影响，对比研究去皮西瓜与完整西瓜光谱在650-950nm范围内的建模结果，完整西瓜二阶微分光谱校正模型相关系数r为0.949，RMSEC为0.292，去皮西瓜校正模型相关系数r为0.973，RMSEC为0.214，果皮对建模结果的影响并不严重，完整西瓜的建模结果可以满足检测要求； 5。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
