- Antioxidant and Antibacterial Activities of Pteris vittata L . . .
Phuong Nhung Nguyen1, Ngoc Lien Nguyen2, Hai Nam Pham1, Phuong Khanh Nguyen1and Kieu Oanh Nguyen Thi1 Abstract Objectives: Pteris vittata L is one of the hyperaccumulator plants that can grow in heavy metal-contaminated soil This plant may tolerate metal stress through different mechanisms, eg, by producing a wide range of secondary metabolites These compounds play an essential role in
- Effects of Se on the uptake of essential elements in Pteris . . .
Abstract Selenium has been proven to be an antioxi-dant in plants at low dosages To understand better the mechanisms of Se toxicity and benefit to plants, more investigations about effects of Se on the uptake of essential elements in plants would be desirable In this study, hydroponic (nutrient solution culture) and pot (soil culture) experiments were simultaneously conducted to investigate
- Phosphorus and Iron Deficiency Stresses Affect Arsenic . . .
Phosphorus (P) and iron (Fe) are essential nutrient elements for plants, which affect plant growth and metabolism The P is a major component of nucleic acids, phospholipids, and intermediary metabolites [15] It has been reported that As(V), as a P analog, is taken up by plants via P transporter systems and both easily form a competitive relationship as a substrate for the phosphate uptake
- The contents of free amino acids and elements in As . . .
The objectives of this study were to analyse the relationship between the contents of elements and free amino acids (AAs) in fronds of As-hyperaccumulator Pteris cretica cv Albo-lineata (PC) and non-hyperaccumulator Pteris stra-minea (PS) during reversible senescence The time-course efect on senescence was also investigated
- Multi-Analytical Approach to Evaluate Elements and Chemical . . .

- Pteris - Little Flower College
In Pteris the first division of the zygote is vertical followed by second transverse division resulting in the formation of a quadrant Further a 32-celled embryo is formed due to further divisions of the quadrant
