摘要: The availability of sufficient irrigation water and the development drought-tolerant species are challenging factors in design maintenance green roofs modern cities. Green roof plants Petunia hybrid Headliner® Red Star, Ageratum Artist® blue, Mentha spicata L. grown a simulated pot system under controlled greenhouse conditions. were watered every 2 or 6 days (2DWI/6DWI) for 8 weeks accompanied by either 6-day treatment seaweed extracts Ascophyllum nodosum as soil drench foliar spray, two concentrations trinexapac-ethyl (TE) biweekly sprays. Following treatments, leaf number, leaf area, dry weights, plant height, stomatal conductanse, photosynthetic transpiration rates potential relative content determined seasons during 2016 2017. prolonged intervals reduced growth revealed morphological physiological parameters. application SWE improved vegetative growth, conductance, intervals. TE increased well performance plants. However, neither nor treatments It was suggested that stimulated enhanced conductance leading to
