Performance of Moroccan Wheat Cultivars under Tillage Systems and Water Regimes

The superiority of wheat grain yield under no-till has been reported by many authors, and others reported significant interaction between wheat cultivar and tillage system for grain yield and other related traits. Hence, new breeding initiatives are needed to introgress favorable traits into wheat and other crops in areas where no-tillage is being adopted. The identification of such traits is solely possible via the assessment ofgermplasm under no-tillage. Moreover, Moroccan wheat breeding programs are carried out solely under conventional tillage system whilst the conservation one is becoming widely adopted. So, the ultimate objective of this research is to find out if the used wheat commercial cultivars behave differentially under no tillage system and to propose the use of appropriate cultivars for the appropriate tillage system and to implement a breeding program specifically for no tillage system. The experiment has been carried out during 2006-2007 at Douyet （F6s）. Cultivars have been sown according to a strip-split plot design. At maturity, yield, yield components and related traits have been recorded. The results indicated that both water regime （WR） and variety （Vat） had a highly significant effect on all measured traits. In contrast, tillage system （TS） had similar effect on yield, grains m-2, biomass, and plant height, but had no effect on harvest index, 1000-kernel weight and heading date. The TSxVar interaction has been significant to highly so on all traits except on heading date. The magnitude of the interaction for grain yield was more important under irrigated treatment than under rainfed one. On the whole, No Tillage yielded more grains than conventional one. Moreover, Achtar and Areal （bread wheat cultivars） and Marjana and Marzak （durum wheat cultivars） yielded more under No-Till. The significant interaction between TS and Var paves the way for the implementation of a breeding program under no till system.     

霉菌毒素的最新研究进展

霉茼毒素（Mycocoxin）是由产毒霉菌产生的次级代谢产物。由于饲料作物在田间、收获、贮藏、加工等诸多环节均可受到霉菌和霉菌毒素的污染,所以饲料及其原料受霉菌和霉菌毒素的污染已成为一个全球性的问题霉菌毒素能导致动物发生自然性的、有毒害性的、生物学上的改变,因此给家畜生产造成极大的危害。本文从霉菌毒素的毒性机理及其吸附剂等方面对其最新的研究进展进行了综述,从而增加人们对霉菌毒素及其危害的认识。

新疆杏制干品种的筛选及制干工艺的初步研究

[目的]筛选适宜的杏制干品种并对其制干工艺进行研究.[方法]对大胡安娜、佳娜丽、库买提、赛买提等46个杏品种的鲜杏自然晾晒制干,通过对46个品种的杏干果肉的总糖、总酸、制干比等指标测定及感官评价,筛选出适宜的杏制干品种.以库买提为原料,通过采用促干剂、蒸汽漂烫、NaHSO_3溶液浸泡、漂烫结合NaHSO_3溶液浸泡等处理方法,经过自然晾晒得到杏干,并对杏干的总糖、总酸、制干比、水分、残留SO_2量进行测定以确定最佳制干工艺.[结果]适宜的制干品种为大胡安娜、黑叶杏、库买提、佳娜丽等.最佳制干工艺条件为整果经90℃热水漂烫3 min,再浸泡于浓度为3.75 g/L的NaHSO_3溶液中1 h后晾晒.[结论]采用该工艺提高了制干速率,制干时间缩短2 d,且杏干感官品质好.
