为更好地利用国外引进的杏(Armeniaca vulgaris Lam.)种质资源,以北寨红杏(A.vulgaris‘Beizhaihongxing')和金太阳杏(A.vulgaris‘Goldensun')为对照,对从匈牙利引进的优质杏品系Hybrid18/79(A.vulgaris‘18/79')和Hybrid1... 为更好地利用国外引进的杏(Armeniaca vulgaris Lam.)种质资源,以北寨红杏(A.vulgaris‘Beizhaihongxing')和金太阳杏(A.vulgaris‘Goldensun')为对照,对从匈牙利引进的优质杏品系Hybrid18/79(A.vulgaris‘18/79')和Hybrid10/10(A.vulgaris‘10/10')的有效花率、自然座果率和自交座果率以及花粉管生长等特性进行研究,同时,通过S-allele-specific PCR扩增程序进行S基因型的分析测定。结果表明:Hybrid18/79、Hybrid10/10和北寨红杏的自交坐果率分别为18.05%,2.27%和1.68%,Hybrid18/79为自交亲和性品系,北寨红杏和Hybrid10/10为自交不亲和品种和品系。与自交亲和的金太阳杏相比,Hybrid10/10自花授粉后花粉管在花柱中生长受到阻塞,至花柱2/3处,花粉管顶端膨大,停止生长,而金太阳杏可以顺利进入胚囊进行受精。Hybrid18/79、Hybrid10/10和北寨红杏的S基因型分别为Su1Su2、S16S16和S30Su1,序列比对发现Hybrid18/79的2个S基因(Su1、Su2)都是新发现的S基因,北寨红杏的一个S基因(Su1)与Hybrid18/79中的一个S基因(Su1)一样,也为新发现的S基因。目前已在GenBank进行了登录,序列登录号为MF685202和MF685203。 展开更多

A field experiment was conducted using Ceranock bait station, "attract and kill" system to combat Mediterranean fruit fly, Ceratitis capitata, in apricot orchards, Central of lraq during the 2013 field season. Control program was implemented in three orchards of mixed apricot varieties. Ceranock traps were hung in each tree of two separate orchards. Delta and McPhail traps were used to monitor Medfly population density in each treated and control orchards. Results indicated that Medfly activity in apricot orchards started during the last week of April coincided with the beginning of maturity for fruits of early varieties. The total of trapped insects in monitoring traps after one week of Ceranock application were 0, 1 and 31 adults for the 1st, 2nd and the control orchards, respectively. Three weeks later and on, the number of trapped adults started to increase dramatically. At the end of apricot season and after 45 days of Ceranock trap application, the number of trapped insects in monitoring traps reached 110, 111 and 2,349 adults/week, respectively, for the 1st, 2nd and 3rd orchard. The use of Ceranock traps reduced Medfly population density by 86%-97%. The percentage of fruit injuries in early maturing varieties were 0.75%, 1% and 34% for the 1st, 2nd and control orchards, respectively. While, late varieties were 2% and 3% for 1st and 2nd orchards, and 69% for the control. The percentage of reduction in fruit damages reached to 95% and 97%, respectively in the 1st and 2nd orchard. The results of this study demonstrate clearly the efficacy of Ceranock bait station, "attract and kill" system as a control measure for Medfly in apricot orchards. 展开更多
