Abstract

Aubergine cultivation experiments were carried out at the Ain Chock Faculty of Science of the Hassan 2 University in Casablanca, to study the effect of potable water (PW), waste water (WW) and treated wastewater (TW) on aubergine crop production and on physico-chemical properties, SDH activity and microbiological properties of aubergine fruits. The aubergine growth was not significantly affected by different treatments. K+, NO3-, lipid, protein and Vitamin C content were insignificant in plant irrigated with TW compared with PW. For the microbiological results, no bacterial colonies of Faecal Streptococcus, Vibrio cholerae or Salmonella were identified in all the fruits studied for any irrigation system and total coliforms and fecal coliforms were below to acceptable limits for plant. The results of SDH activity showed that leaves presented higher activity compared to fruits and roots. Treated wastewater can be a resource for agricultural irrigation.

处理后的摩洛哥卡萨布兰卡废水灌溉茄类作物的生长、SDH活性和微生物特性

在卡萨布兰卡哈桑2大学Ain Chock科学学院进行了茄子栽培试验，研究了饮用水(PW)、废水(WW)和处理废水(TW)对茄子作物生产以及茄子果实理化特性、SDH活性和微生物特性的影响。不同处理对茄子生长无显著影响。与PW相比，TW灌水对植株K+、NO3-、脂肪、蛋白质和维生素C含量影响不显著。微生物学结果显示，在所有灌溉系统的水果中均未发现粪便链球菌、霍乱弧菌或沙门氏菌菌落，总大肠菌群和粪便大肠菌群均低于植物可接受限度。SDH活性测定结果表明，叶片的SDH活性高于果实和根。处理后的废水可作为农业灌溉的资源。
