Toxicity of cadmium on the growth and yield of Solanum melongena L.

چکیده
Heavy metal cadmium is biomagnified through food chain and causes Itai-Itai disease in human. The present investigation reports the results of the effect of cadmium on seed germination, germination relative index (G.R.I.), seedling growth, chlorophyll stability index (CSI) and yield of Solanum melongena L. cv Pusa uttam. Effect of different concentrations of heavy metal cadmium (CdCl2) in Hoagland's nutrient solution (10(-2) M, 10(-4) M, 10(-5) M and 10(-8) M) were employed for all seedling and physiological parameters of brinjal. Cadmium showed toxic effects at high concentrations 10(-2) M but promotory at lower concentration (10(-8) M) with regard to growth and yield.

Seedlings of aubergine (Solanum melongena L.) cv. ‘Rima’ were used as scion (R) and control (non-grafted) and rootstock (self-grafted) (RR), while two hybrid tomatoes ‘Heman’ (Lycopersicon hirsutm) and ‘Primavera’ (Lycopersicon esculentum) were used as rootstocks. Grafted and non-grafted plants were grown in the greenhouse and in the open-field. Grafted plants Rima and Heman (RH) were more vigo...
متن کاملStudy of Variation of Yield and Morphological Traits of Some Local Varieties of Iran’s Eggplant (Solanum melongena L.)
Eggplant is a crop that has been cultivated for a long time in different areas of Iran. Nevertheless, no sufficient studies have been done on variation of morphological traits and yield of this crop in Iran, and it has not been well-attended in breeding programs. Therefore, to study genetic diversity in collected local varieties, the experiment was conducted in a Randomized Complete Block Desig...

Salinity is a serious problem for expansion of agriculture, especially in arid and semi-arid regions. On the other hand, various benefits of soilless culture have caused the expansion of this system in these areas. In order to investigate the effect of different levels of salicylic acid and salinity stress on vegetative and physiological characteristics of eggplant, a factorial experiment was c...
