rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

the aim of this study was to assess the effects of heavy metal tolerant soil microbes inoculation on growth and metal uptake of pearl millet (pennisetum glaucum), couch grass (triticum repens) and alfalfa (medicago sativa) in a soil spiked (and subsequently aged) with increasing concentrations of pb. a soil sample (soil 1) was spiked with increasing (0 to 1500 mg/kg) concentrations of pb and in...

taro (colocasiaesculental. schott) is a perennial root crop that belongs to araceace family. it is widely cultivated as a staple food in africa, asia and pacific islands. despite its importance, there is limited information on many aspects of the crop. in order to obtain data that can support improved and sustainable taro production, a field trial was conducted to study the effects of corm size...

the effects of the plant growth promoter gibberellic acid (ga3) and plant growth retardant chlormequat chloride (ccc) on biomass and quality of angelica dahurica var.formosana plants were investigated employing physiological and biochemical methods. plants were sprayed with ga3 or ccc at rosette stage and coumarin content was analyzed by high performance liquid chromatography (hplc) after harve...

the aim of this review was to represent a category of applied plant biostimulants and to highlight the effect of their application on morphological and phytochemical properties of medicinal plants in in vivo and in vitro conditions and their mechanism of action. plant biostimulants, safe for both human beings and the environment, are substances or materials, except for nutrients and pesticides,...
