Abstract

The study was executed to assess individual and interactive effects of elevated ultraviolet-B (eUV-B) radiation and chromium (Cr) on a medicinal plant Adhatoda vasica Nees. The experiment was conducted under field conditions involving control, Cr, eUV-B, and Cr+eUV-B treatments. The results showed that Cr content was the highest in roots as compared to other parts under Cr+eUV-B. Significant reductions in photosynthetic rate, intercellular CO2 concentration, and stomatal conductance were observed under all treatments with maximum under Cr+eUV-B. Chlorophyll (Chl) fluorescence parameters showed variable responses under Cr and Cr+eUV-B. Chl content showed reductions under all treatments whereas Chl a/b ratio and carotenoids showed increment under eUV-B and reductions under Cr and Cr+eUV-B. The ultrastructure of leaves showed changes in chloroplasts under treatments. Vasicine (medicinally important secondary metabolite) increased under treatments. Our study revealed that A. vasica showed variable responses towards individual and interactive stress of Cr and eUV-B.

Abstract

Ultraviolet-B is an important fraction of sunlight which influences the plant performance either positively or adversely in terms of growth, physiology, biochemistry, and major active compounds. The static nature of plants constrains them to be subjected to various adverse environmental conditions. Several studies performed with plants and UV-B with fewer reports are available on medicinal plants having rhizome. The present study focuses on transformation induced in two Curcuma spp. (C. caesia and C. longa) under the influence of elevated UV-B (eUV-B) (ambient ±9.6 kJ m−2 d−1) under natural field conditions to analyse the changes in physiological, biochemical and essential oil of the test plants. eUV-B significantly reduced the photosynthetic activities such as photosynthetic rate (Ps), stomatal conductance (gs), transpiration (Tr), internal CO2 (Ci), and photochemical efficiency (Fv/Fm) with higher reductions in C. longa as compared to C. caesia. The enzymatic activities of PAL, CHI, and CAD showed higher stimulation in C. caesia whereas C. longa showed increment only in CAD. The essential oil content was increased by 16% and 9% in C. caesia and C. longa, respectively. C. caesia showed increased monoterpenes than sesquiterpenes, whereas almost equal increase of both the terpenoid found in C. longa. C. caesia showed induction of aromatic compounds (epiglobulol, germacrene, 4-terpineol), whereas anticancerous compounds; aphla-terpinolene (61%), beta-caryophyllene (60%), and beta-sesquiphellandrene (32%) were increased in C. longa. C. caesia acted well in terms of both physiology and major active compound (1, 8-cineole), but overall most of the compounds increased in C. longa under eUV-B.

Abstract

This book presents updated and relevant information on the tropospheric ozone problem and its effects on the plants and human health. The contributions here present in-depth knowledge about history, pattern, sources, environmental factors and other necessary aspects of the tropospheric ozone problem. The book provides a balanced view of current developments on the effects of the tropospheric ozone on plant and human health, crop production and ecosystem services. In addition to the effects of the tropospheric ozone on growth and physiological and biochemical traits, it also considers the molecular basis of plant responses to ozone. The book encompasses a holistic view on various interconnected issues of ozone pollution, and will appeal to scientists from all over the world.

Abstract

A three noded, 18 d.o.f. beam element is developed for beams of variable rectangular cross section, arbitrarily curved in space. The superparametric beam element is combined with the existing eight noded, 40 d.o.f. superparametric shell element for shell beam systems. To show the applicability of the formulations, some simple problems of beams and a four-beam slab are analysed.
