Alleviating Effect of Foliar Sprayed Paclobutrazol and Salicylic Acid on Biochemical Changes in Mungbean under Cadmium Stress

Histochemical and ultrastructural analyses were carried out to assess structural and biochemical changes in date palm roots pretreated with salicylic acid (SA) then inoculated withFusarium oxysporumf. sp.albedinis(Foa). Flavonoids, induced proteins, and peroxidase activity were revealed in root tissues of SA-treated plants after challenge by Foa. These reactions were closely associated with plant resistance to Foa. Host reactions induced after inoculation of SA-treated plants with Foa included the plugging of intercellular spaces, the deposition of electron-dense materials at the sites of pathogen penetration, and several damages to fungal cells. On the other hand, untreated inoculated plants showed marked cell wall degradation and total cytoplasm disorganization, indicating the protective effects provided by salicylic acid in treated plants.

Exogenous Application

Abstract Cadmium (Cd+2) is a potentially toxic element that inhibits growth and development of several species of plants along with Silybum marianum (L.) Gaertn which is an essential medicinal plant belonging to family Asteraceae. The exogenous application with 0.25µM Salicylic acid (SA) and 10µM hydrogen peroxide (H2O2) to ameliorate harmful effects of cadmium (500 µM) on milk thistle were studied that were grown at two different ecological zones of Balochistan province of Pakistan i.e. Quetta (Qta) and Turbat (Tbt). The design of experiment was Randomized Complete Block Design (RCBD) with three replicates. Application of SA and H2O2, priming (P), Foliar spray (FS) and combinational treatments (P+FS) were highly helpful in alleviating the negative role of cadmium toxicity. The essential nutrients i.e. nitrate (NO3-), calcium (Ca2+) and potassium (K) were affected by Cd+2 induced toxicity however, the substantial role of SA and H2O2 widely helped to reduce the cadmium stress and boosted up the plant nutrients content. In a nutshell, exogenous treatments of SA and H2O2 enhanced the yield potential along with highest silymarin contents in milk thistle seeds which is of prime significance for its medicinal importance in treatment of liver diseases. The data obtained in this study highly recommend the priming and foliar spray of SA and H2O2 on milk thistle plants, as the best solution to alleviative the cadmium toxicity which will ultimately leads to better growth and yield of the plants.
