通过桃园间作薄荷(Herba menthae)、迷迭香(Rosmarinus officinalis)、薰衣草(Lavandula pedunculata)、三叶草(Trifolium)、黑麦草(Lolium perenne)、苜蓿(Medicago sativa Linn)、红薯(Ipomoea batatas)、花生(Arachis hypogaea)等草本植物,分别测定了各间作区土壤中有机碳及速效氮、速效磷和速效钾含量,从土壤有机碳和速效(N、P、K)的角度,分析了桃园间作对土壤碳库的影响和有机碳与土壤速效(N、P、K)间的相互关系.

遗传连锁图谱是遗传育种工作的重要技术平台,是进行重要性状基因定位克隆及基因组学研究的基础和依据.果树是多年生植物,对其功能基因的定位、筛选和克隆等研究的方法十分有限,而遗传图谱作为研究控制作物重要性状基因的有效途径之一,在果树上则更具有实际的应用价值.本研究中利用建立的EST-SSR,SCoT等新型分子标记技术构建柑橘高密度遗传图谱,以期为柑橘的遗传育种研究提供必要辅助.
马铃薯(Solanum tuberosum)块茎中含有丰富的碳水化合物,具有很高的营养价值和药用价值,其中淀粉是马铃薯块茎中的主要贮藏物质,淀粉含量是评价马铃薯品质优劣的重要指标之一.抗性淀粉(Resistance Starch,RS)是不被健康人体小肠吸收的淀粉及其水解物的总称,具有增加肠胃蠕动,降低餐后血糖浓度,减少心脏病发生频率等有重要的保健功能和医疗作用.
