Physiological, nutritional and tolerance effects in Chrysanthemum morifolium irrigated with grey and treated water

Abstract

This research provides basic information on the recovery or reuse of grey and treated water in a sustainable approach. For the research development, treated water was collected and synthetic greywater was prepared to use for irrigation of potted plants and their adaptability was measured according to the different irrigation water and physicochemical parameters in plant and soil. The results show that plants with the highest flowering and the highest accumulation of NOз in the stem were the plants irrigated with treated water in response to the total nitrogen of 41.53 mg/L. The plant's adaptability was more complicated with the irrigation of greywater but with greater growth and more resistance to pests and diseases than with the irrigation of treated water. The response to the accumulation of As, Ag, Cr, P, Pb, S, and Ti was significant differences according to the irrigation water in the different organs of the plants. During the crop development under the different types of irrigation, the pot soils are within the Mexican regulation, which presented neutral pH, slightly saline, with high organic matter, and without problems of dangerous accumulations of heavy metals.
