| 中文摘要: |
| 阿蒂莫耶番荔枝对水淹胁迫敏感，而圆滑番荔枝（Annona glabra）耐淹水性强，是理想的耐淹水砧木。但是，阿蒂莫耶番荔枝与圆滑番荔枝存在嫁接不亲和的问题。本研究以圆滑番荔枝（取代号Ｇ）作基砧，阿蒂莫耶番荔枝（A. atemoya Hort.）African Pride品种牛心番荔枝（A. reticulata）的杂交种（AR）作中间砧，取阿蒂莫耶番荔枝4个品种 African Pride （AP）、Paxton (P)、 Pink’s Mammoth (PM)和Bullock’s Heart (BH)的一年生枝条作接穗，用切接法展开嫁接试验。结果表明，不同品种间的切接成活率没有差异，其中，AP/AR/G（接穗/中间砧/基砧）的春季和夏季嫁接成活率分别为83.7%和77.9%，嫁接苗在苗圃和三年的田间种植中，生长均表现正常，说明利用AR中间砧可很好地解决阿蒂莫耶番荔枝与圆滑番荔枝嫁接不亲和的问题。研究还表明，夏季嫁接时，用AP番荔枝的春季采集的1年生枝梢作接穗的成活率（77.9%）比用当季成熟春梢作接穗的成活率（38.1%）明显更高。 |
| 英文摘要: |
| Annona atemoya Hort is susceptible to flooding, while Annona glabora (G) is highly flooding resistant and can serve as an excellent flooding-resistant rootstock for Annona crops. However, there is problem of incompatibility when A. atemoya is grafted onto A. glabora. In this study, A. glabora (G) was used as rootstock, the hybrid (AR) of A. atemoya cv. African Pride A. reticulate as interstock, and the one-year-old budwoods from four cultivars of A. atemoya, ie. African Pride (AP), Paxton (P), Pink’s Mammoth (PM) and Bullock’s Heart (BH) were used as scions for the grafting tests. The results showed that there was no difference in survival rate among the scion cultivars. Among them, the survival rate of spring and summer grafting of AP/AR/G (scion/interstock/rootstock) reached 83.7% and 77.9%, respectively. The grafted trees maintained normal growth in the nursery and in the field for three years, suggesting that the use of the interstock had well solved the problem of incompatibility between A. atemoya A. and glabora. When grafting was conducted in summer, the one-year-old budwoods as scions, which were collected in spring and stored by inserting them in soil, had a significantly higher survival rate than current-season mature spring shoots as scion (77.9% vs 38.1%). |
