Plant tissue has biologically closed electrical circuits and electric fields that regulate its physiology. The biologically closed electrochemical circuits in the leaves of Aloe vera were analyzed using the charge stimulation method with Ag/AgCl electrodes inserted along a leaf at 1-2 cm distance. The electrostimulation was provided with different timing and different voltages. Strong electrica...

The relative impermeability of the surfaces of leaves to water and mineral ions in solution is a condition upon which the life of terrestrial higher plants depends. However, for the investigator this feature imposes difficulties on attempts to make quantitative studies of the process of ion absorption by leaf tissue. The importance of this absorption process in the physiology of leaf cells has ...

Abstract—Specific leaf area (SLA; cmleaf gleaf) the ratio of leaf area to leaf dry mass is a key ecophysiological parameter influencing leaf physiology, photosynthesis, and whole plant carbon gain and also can be used as a rapid and diagnostic tool. In this study, two species of soluble inorganic selenium forms, selenite (Se) and selenate (Se) at different concentrations were investigated on ma...

The study was conducted on physiology and biochemical performance and correlation for yield and its quality characters of 18 genotypes of Glory lily (Gloriosa superba). Experiment was laid out in a randomized block design with three replications at the Medicinal Plants Unit, Botanical Garden, Tamil Nadu Agricultural University, Coimbatore. Genotypes GS 15, GS 06, GS 18, GS 03 and GS 02 were com...

Leaf shrinkage with dehydration has attracted attention for over 100 years, especially as it becomes visibly extreme during drought. However, little has been known of its correlation with physiology. Computer simulations of the leaf hydraulic system showed that a reduction of hydraulic conductance of the mesophyll pathways outside the xylem would cause a strong decline of leaf hydraulic conduct...

Heteroblastic plants produce markedly different leaf morphologies between juvenile and adult stages, while homoblastic plants exhibit little or gradual changes. We tested the hypothesis that the leaf morphology of the seedling stage of New Zealand heteroblastic species is advantageous in dealing with low light levels found in forest understorey. We used four independent contrasts of heteroblast...

Background: The Gundilia tournefortii leaf contains the chemical compound such as saturated and unsaturated fatty acids. Saturated fatty acid includes stearic and palmitic acid and unsaturated include linoleic and oleic acid, that, these compounds inhibit 5 reductase enzyme. The present study was carried out with the aim of determining the effect of Gundilia tournefortii leaf on spermatogenesis...

Understanding the vertical pattern of leaf traits across plant canopies provide critical information on plant physiology, ecosystem functioning and structure and vegetation response to climate change. However, the impact of vertical canopy position on leaf spectral properties and subsequently leaf traits across the entire spectrum for multiple species is poorly understood. In this study, we exa...

Indirect plant-mediated interactions between herbivores are important drivers of community composition in terrestrial ecosystems. Among the most striking examples are the strong indirect interactions between spatially separated leaf- and root-feeding insects sharing a host plant. Although leaf feeders generally reduce the performance of root herbivores, little is known about the underlying syst...

The impacts of Dust and Sand Storms (DSS) on people, crops, livestock, infrastructure and health are well documented. Data have accumulated on the deleterious effects of dust aerosols when they settle on plants. Sand blasting of low growing plants is a common cause of failure in reforestation efforts. Burial of plants by moving sands are also a cause of much damage. The physics of moving sand a...
