ABSTRACT:

Oxalis corniculata Linn is one of the known useful medicinal plant commonly known as yellow wood sorrel which has been used since ages for the treatment of various ailments and also used as a food at the time of scarcity. Under acidic condition, Aluminium(Al) toxicity is one of the potential growth-limiting factor for plants among the abiotic factors. Silicon (Si) is one of the most prevalent macroelements found in soil, can improve the condition of soils. In the present study experiments were conducted for cell death assessment in Oxalis corniculata Linn. The experimental setup was completely randomized with three treatments (0, 1.6 mmol/L Al, and 1.6 mmol/L Al + 2.0 mmol/L Si; being described as the control, Al toxicity and Al toxicity + Si, respectively). Treatments were given for two time intervals – 2hrs and 4hrs. The loss of cell viability or cell death was evaluated using Evan's blue staining method. The result showed plants that were aluminium stressed showed higher cell death as compared to control when the treatments were given for 2hrs and 4hrs on the other hand Si application results in lesser cell death for both the treatments (2hrs and 4hrs) as compared to aluminium stressed plants.
