- Abstract:
- ... The photosynthetic responses of clusterbean (Cyamopsis tetraganoloba) cotyledons exposed to UV-A, UV-B or UV-A + UV-B radiation for 1 h daily until day 10 have been compared. The loss in the rate of O-2 evolution and CO2 assimilation (P (n)) are incommensurate with each other in both UV-A and UV-B exposed samples indicating the occurrence of loss in photostasis of photosynthesis by these two radia ...

The effects of exposure of barley seedlings to different concentration (10(-6) to 10(-3) mol/l) of paraquat on seed germination, root length, antioxidant enzyme activities and randomly amplified polymorphic DNA (RAPD) profiles were investigated. The results revealed that malondialdehyde content significantly increased by exposing paraquat in a concentration-dependent manner (p < 0.05). A significa ...

Salt stress is among the major abiotic stresses that adversely affect the global crop production and its adverse impacts are getting more serious in the regions where saline water is used for irrigation. It induces reactive oxygen species, alters the activity of antioxidant system and adversely affects the process of photosynthesis. Various strategies have been employed to mitigate the deleterious ...

However, in orchids, the importance of mycorrhizal fungi in nutrient acquisition is not as extensively studied as in other plants. Therefore, an in vitro culture system to study the effects of mycorrhizal association on P ...

The change in tensile stress from 6 to 40 MPa caused the increase in cell wall elastic modulus from 0.4 to 3 GPa. Lowering the temperature from 30 to 4 A degrees C resulted in instantaneous and reversible cell wall e ...

- Abstract:
- ... Biosynthesis of proline - or other compatible solutes - is a conserved response of all organisms to different abiotic stress conditions leading to cellular dehydration. However, the biological relevance of this reaction for plant stress tolerance mechanisms remains largely unknown, since there are very few available data on proline levels in stress-tolerant plants under natural conditions. The aim ...
