摘要
采用早熟优质小型西瓜‘早佳’为接穗和对照,丝瓜、南瓜(‘铁木真’)、葫芦(‘昌砧力士F1’)、‘野生西瓜1号’、‘野生西瓜2号’为砧木,研究5种砧木对西瓜嫁接苗生长及商品性状的影响。结果表明,嫁接栽培影响植株长势和雌花坐果节位;嫁接提高了植株(接穗)自身的抗病能力;与对照相比,嫁接后果实单果重(除丝瓜/早佳组合)、果皮厚、中心糖含量(除丝瓜/早佳组合)均极显著上升,边缘糖含量极显著降低;南瓜/早佳和葫芦/早佳组合极个别果实有异味,但不影响食用。5种嫁接组合中,野生西瓜/早佳组合极个别果实中出现空洞。综合田间性状,丝瓜不适合作早佳西瓜砧木,南瓜和‘野生西瓜2号’砧表现最佳,葫芦和‘野生西瓜1号’砧居中。
Effect on the plant growth and commercial characters by grafting in watermelon was studied in this research. Wild watermelon 1 and wild watermelon 2, pumpkin（Tiemuzhen）, calabash（Changzhanlishi S1 ）and loofah were used as five different rootstocks and Zaojia was taken on the CK. The re suits indicated that plants growth and fruit set node of the female flower were affected by grafting and antiviral ability was all improved by the different grafting rootstocks. Compared with CK, first, the weight of single fruit and central sugar content were all extremely significantly increased excepting for loofah/Zaojia treatment,thickness was extremely significantly too and marginal sugar content was different extremely significantly decreased by grafting among these treatments. Second, some fruits of pumpkin/Zaojia and calabash /Zaojia have peculiar smells, but which have not effects on edibility. Some fruits of wild watermelon/Zaojia have cavities. Zaojia was inapplicable to be grafted with loofah, wild watermelon 2 and pumpkin were the best rootstocks, and calabash and wild watermelon 1 rootstocks were in middle synthetic character of the field.
