The orange-head Chinese cabbage attract the interest of the consumers and breeders because it accumulate higher amounts of carotenoids and lycopene in comparison with the normal white head cabbage.The
Phytyl diphosphate (PDP) is the prenyl precursor for tocopherol biosynthesis.Based on recent genetic evidence,PDP is supplied to the tocopherol biosynthetic pathway primarily by chlorophyll degradatio
The fatty acid desaturase 2 (fad2 ) gene was proven to be the major locus for high oleic acid ( C18:1 ).Brassica napus is an amphidiploid species originating from a spontaneous hybridization of Brassi
To develop various doubled haploid (DH) lines in Kimchi cabbage(Chinese cabbage),we performed microspore cultivation using 95 varieties from China,Japan and Korea.12 varieties produced embroids and ab
Polyunsaturated fatty acids (PUFAs) play important roles on human health,among which γ-linolenic acid (GLA) is the precursor for synthesizing prostaglandin.Δ6 fatty acid desaturase (D6D) is the key en
Maize (Zea mays L.) is one of the most important cereal crops world-wide as well as an important source of feed,fibre,and biofuel.Potassium (K) as one of the essential nutrients for crop plays an impo
农业生产受全球气候变暖的影响非常大，因此当前及未来气候变暖带来的粮食安全问题已引起人们的普遍关注。近几十年，众多学者对作物种植制度、生长发育和产量对气候变化的响应展开了大量研究并指出，气候变暖使我国农区的热量资源普遍增加，以高纬度地区为典型，已造成多熟制北界北移西扩，作物由早中熟向中晚熟转变，使作物生产潜力提高。国内学者对春玉米的研究多集中于东北三省、华北平原和陕甘地区，而北疆作为新疆春玉米的主要
[研究目的]研究不同播期对不同品种玉米果穗分蘖率的影响,明确影响果穗分蘖的气象因素,对于通过调整播期实现果穗良好建成及逆境条件下预测产量形成具有重要意义.[试验设计]试验于2013年3月-11月在湖北省武穴市现代农业示范中心试验基地(30°00′N,1 15°44E)进行,试验采用裂区设计,播期为主区,品种为副区,各小区面积为8行区,宽4.8m,长7m,重复3次.共设计10个播期,播种时间为3/1
Conservation tillage is widely utilized in the dryland regions of northern China.Tillage treatments can generate changes in the physical and chemical properties of the soil,affecting the soil bacteria
小麦和玉米是重要的粮食作物，其产量分别占全球粮食总产的36％和26％。中国是主要的小麦和玉米生产国，同时我国也是农田碳排放较大的国家之一。小麦-玉米一年两熟是华北平原主要的作物种植模式，为了进一步提高该区作物产量和氮肥利用效率，许多优化施肥、土壤耕作等新技术已经广泛应用于农业生产。但是不同耕作方式对小麦和玉米周年产量、氮素利用效率及其环境效应的综合影响还少见报道。因此，本试验以小麦-玉米一年两熟模
