项目简介 :
目标:
要确定猕猴桃种质资源的耐寒冷生长条件,以确定它们在西北太平洋地区潜在的生产范围。确定驯化率、降温幅度以及萌芽、开花和收获的总需冷却时间之间是否存在相关性。
方法:
在西北太平洋地区基于商业生产潜力,从全国无性系种质资源库选育15个最有前景的耐寒性猕猴桃种质资源,研究商业化种植的猕猴桃'Ananasnaya'、'Issai'、74-49以及A. deliciosa 'Hayward'。在秋季、冬季以及2005年6月份,从10月15日到3月15日 每两个星期从每个种质资源中收集10个组织样本,每个组织样品将是一年5节点果实手杖节。然后将组织样本放在温室(15至20摄氏度,自然日照)条件下的平底花盆中进行培育,底部供热并供水(最好的方法确定在2004年05月份)。每日将评价组织样品中萌芽所占的百分比,届时它们将被丢弃。在2006年的春季或者夏季,将收集萌芽日期、第一次和最后一次开花的时间以及收获果实的日期(female vines),对这些数据和冷却要求条件之间的相关性进行分析。这项研究与美国俄勒冈州立大学签订了一项特定的合作协议。

2005 Annual Report
4d.Progress report.
This report serves to document research conducted as a result of a specific cooperative agreement between ARS and the Oregon State University, Department of Horticulture. Additional details of research can be found in the report for the parent project 5358-21000-033-00D, "Management of Temperate Adapted Fruit, Nut, and Specialty Crop Genetic Resources and Associated Information".
In the Fall/winter 2005-2006, 10 tissue samples will be collected from about 10 different cultivars of hardy kiwifruit that are established at the USDA ARS National Clonal Germplasm Repository in Corvallis, Oregon, and the North Willamette Experiment Station of Oregon State University, in Aurora, Oregon. These samples will be collected every two weeks from October 15 through March 15. Samples will consist of a 5 node, 1 year old fruiting cane section. Samples will be forced under warm conditions. The days to bud break will be counted and contrasted to determine the chilling requirement for each cultivar. In the spring 2006, date of bud-break, first and last flower, and fruit harvest date (female vines) will be collected. A correlation analysis between these data and the chilling requirement will be performed. This will be he first year of a two year study. Reports will be written after the two years data are collected.

Evaluation of Hardy Kiwifruit Germplasm
This report serves to document research conducted as a result of a Specific Cooperative Agreement between ARS and Oregon State University, Department of Horticulture.

2007 Annual Report
1a.Objectives (from AD-416)
To determine the chilling requirement of hardy kiwifruit germplasm to ascertain potential production range in the Pacific Northwest. Determine whether there is a correlation between rate of acclimation, deacclimation, and total chilling requirement on time of bud break, bloom, and harvest in the field.
1b.Approach (from AD-416)
Fifteen of the most promising hardy kiwifruit accessions housed at the National Clonal Germplasm Repository were selected based on commercial potential for the Pacific Northwest. The commercially grown Actinidia arguta 'Ananasnaya', 'Issai' and 74-49 and A. deliciosa 'Hayward' will be studied. In fall/winter 2005/06, 10 tissue samples were collected from each accession every two weeks from October 15 through March 15. Each tissue sample was a 5-node one-year-old fruiting cane section. Tissue samples were placed in potting media in flats in a greenhouse (~ 15 to 20C, natural daylength) with bottom heat and misting or in flasks with water (best methodology determined in 2004/05). Tissue samples were evaluated daily for percentage of bud break and days to budbreak - up to 30 days, after which time they were discarded. In spring/summer, 2006, date of bud break, first and last flower, and fruit harvest date (female vines) was collected. A correlation analysis between these data and the chilling requirement will be performed. This study documents a Specific Cooperative Agreement with Oregon State University.
3.Progress Report
This report serves to document research conducted under a Specific Cooperative Agreement between ARS and Oregon State University. Additional details of research can be found in the report for the parent project 5358-21000-033-00D, Management of Temperate Adapted Fruit Nut and Specialty Crop Genetic Resources and Associated Information. Samples of fifteen promising hardy kiwifruit accessions from the USDA ARS Corvallis Repository Genebank and Oregon State University North Willamette Research and Extension Center were collected in fall winter 2005/2006 and 2006/2007. These dormant samples were examined for days to budbreak, first and last flower and fruit harvest date(female vines). A correlation analysis between these data and the chilling requirement for each cultivar will be performed. Results will be published in a journal article and presented at annual small fruits meetings. The rate of acclimation, deacclimation and the total chilling requirement to time of budbreak, bloom, and harvest will be determined. This information will assist berry growers in the Pacific Northwest to choose appropriate cultivars for production. ADODR Statement: This is the second year of the project, Evaluation of Hardy Kiwifruit Germplasm. The ADODR met with the cooperating PI at small fruits meetings during the year and discussed results through phone calls and e-mail. Data was collected last winter and this winter and being analysed and interpreted. Preliminary results were reported at the Northwest Center for Small Fruits annual meeting in December 2006. The total funding for this project will be expended within the alloted time and the data will be published in a collaborative journal article.
