Abstract:

UV-B radiation affects crop plants. Growing interest has been shown in studying the effectsof UV-B radiation exclusion on crops since 1993. This article summarized the generalconsequences of UV-B radiation exclusion on crop plants from the aspacts of plant morphology,growth and development. UV-B exlusion has promoting effects on plant height, internodeand leaf size. UV-B exclusion increases root biomass and stimulates nodulation of legumecrops with increased number and size of nodules and enhances the leghemoglobin. Higherlevels of α-tocopherol is found in UV-B plants, which plays an important role in translocatingphotoassimilates from the leaves to the roots. UV-B exclusion could be a useful tool forphysiologists and molecular biologists to further address mechanisms involved in UV-Bradiation damage in crop plants.

Molecular responses of plant cells to UV-B radiation

UV-B radiation (UV-B: 280-320 nm) can cause a wide range of responses in plant cells. These responses depend on the perception of the UV-B radiation, signal transduction mechanisms and modification of gene expression. Studies over the last ten years have revealed a complex molecular response of plant cells to UV-B radiation. Specific changes in gene activity take place and a number of signal tr...

Cuphea Growth and Development: Responses to Temperature

INTRODUCTION Species from the genus Cuphea, Lythraceae, are known to produce seed rich in medium chain fatty acids (MCFA), which are important feed-stocks in the manufacturing of soaps and detergents and numerous other related products (Thompson 1984). In the US there are no crops grown that serve as an economical replacement of MCFA. Consequently, the US chemical industry imports most MCFA as ...

Nonverbal responses to social inclusion and exclusion

Applying an elaborate and novel experimental paradigmwe collected non-verbal responses to social inclusion and exclusion. A judgement experiment revealed that it was possible to determine whether a person was included or excluded, based solely on non-verbal, behavioral cues, especially if the person was male. A detailed coding using the ECSI scale suggests that included speakers displayed more ...

Response of conifers to UV-B and climate in mountain areas

The present study was focused to examine the combined effects of climate and ultraviolet-B radiation on conifer tree-ring density. Statistical methods were employed to extract tree responses in annual ring density and to identify functional relationship in trees when the level of ultraviolet-B radiation changes regardless of climate variations. In this study, the consideration was given to the ...

Differential responses of growth and nitrogen uptake to organic nitrogen in four gramineous crops.

The capability to utilize different forms of nitrogen (N) by sorghum (Sorghum bicolor), rice (Oryza sativa), maize (Zea mays), and pearl millet (Pennisetum glaucum) was determined in pot experiments. Seedlings were grown for 21 d without N, or with 500 mg N kg(-1) soil applied as ammonium nitrate, rice bran or a mixture of rice bran and straw. No treatment-dependent changes of root length, surf...
