We present evidence for two behaviors influenced by intact, vegetative plant odor - upwind flight and abdomen curling - in female Manduca sexta and demonstrate the influence of the age and mating status of the moths on these behaviors. We compared the behavioral responses of laboratory-reared M. sexta. of discrete ages and physiological states (2,3, and 4 day old for virgin; 2 and 3 day old for...
Anatomical and physiological changes in Indian mustard (Brassica juncea) plants due to uptake and accumulation of Zn and Cd were investigated. Potted plants were exposed to metal treatments of Zn and Cd for 15 and 16 days, respectively. Leaves, stems and roots were harvested for studying anatomy and analyzing metal accumulation. Anatomical changes were documented using light microscopy, scannin...
Using potted sugar beet plants we aimed to investigate the suitability of four fluorescence indices to detect and differentiate the impact of nitrogen supply, water deficit and powdery mildew in two sugar beet cultivars (Beta vulgaris L.). Plants were grown inside a polytunnel under two nitrogen levels combined with water deficit or full irrigation. Changes in plant physiology were recorded at ...
Naive mated female cabbage looper moths, Trichoplusia ni Hübner, responded in a flight tunnel to potted potato plants ( Solanum tuberosum ). Percentages of moths attracted to uninjured potato plants, mechanically-damaged potato plants, and potato plants treated with regurgitant from larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say, were similar, indicating no effect of plant ...
Plant transpiration is the dominant water flux in global terrestrial balance and a key process hydrological sciences. Stable isotopes have contributed greatly to this understanding but one difficult assumption for plant source quantification using hydrogen oxygen that no isotopic fractionation occurs during uptake transport within plant. Here we present simple glasshouse experiment with two pot...
Photosystem II (PSII) herbicides have been detected in nearshore tropical waters such as those of the Great Barrier Reef and may add to the pressure posed by runoff containing sediments and nutrients to threatened seagrass habitats. There is a growing number of studies into the potential effects of herbicides on seagrass, generally using large experimental setups with potted plants. Here we des...
An efficient in vitro regeneration protocol has been developed from shoot tips of Drosera burmannii Vahl., a carnivorous plant of north-east India. Various plant growth regulators were used to study their efficacy in the induction of multiple shoots and roots. Of the various treatments, the maximum number of shoots (28.8 ± 1.5) and roots (9.7 ± 0.6) was observed in one-fourth strength standard ...
The impact of Argopistes tsekooni Chen (Coleoptera: Chrysomelidae), a herbivore, on Chinese privet, Ligustrum sinense Lour. (Scrophulariales: Oleaceae), an invasive shrub in the United States, was studied in China. Five densities of adults were inoculated into 3-year-old potted Chinese privet plants in cages under field conditions for 1 month. Plants exposed to high densities of adults were sev...
