Phytotoxicity dynamics of decaying plant materials

Phytotoxicity dynamics of decaying plant materials.

Allelopathic effects of plant litter have been extensively studied, but less attention has been given to the dynamics of phytotoxicity during the decomposition processes. Decomposition experiments were carried out on above- and below-ground plant materials of 25 species of different functional groups (nitrogen fixer, forbs, woody and grasses-sedges) in aerobic and anaerobic conditions. The phyt...

Immunomodulatory, antileishmanial and phytotoxicity of Arisaema Jacquemontii Blume plant extracts

ArisaemajacquemontiiBlume (Araceae) is reputed for its physiological properties in the folk medicine system and used in Chinese herbal medicine as anti-convulsant. Methanolic extracts of roots and fruits, the chloroform extracts of roots and shoots of ArisaemajacquemontiiBlume were investigated for immunomodulatory,antileishmanialand phytotixic activities. Immunomodulatory activitywas investiga...

Behavior and impact of zirconium in the soil-plant system: plant uptake and phytotoxicity.

Zirconium (Zr) is a transition metal that has both stable and radioactive isotopes.This metal has gained significant attention as a major pollutant of concern, partly because it has been prominent in the debate concerning the growing anthropogenic pressure on the environment. Its numerous past and present uses have induced significant soil and water pollution. Zr is generally considered to have...

Dynamics of a discrete-time plant-herbivore model

Pectic Content of Plant Materials.

Many plants and plant materials such as wood (2), tea (25), tobacco (15), cotton (16), hops (13), ramie (11), flax (12), grass (6), potato (10), plantain seed (20), celery (9), limes (22), guava (1), bergamnot (23), and root hairs (21), have been shown to contain pectic compounds. Because different methods of extraction and analysis were employed, it is impossible to iiiake comparative studies ...
