Infection is distributed by thrips adults or budding of plants. Economic significance: INSV is widespread in Europe, America, Asia, and recently in Iran; in roses, this leads to reduce the quality of flowers and amount of essential oil. Disease symptoms: Disease symptoms are similar to tomato ...
Urbanization is changing the conditions in which many species live, forcing them to adjust to these novel environments. Floral size and shape are critical traits for the reproduction of plants pollinated by animals as they are involved in the attraction of pollinators and in efficient...
Daisies (Gerbera jamesonii) are perennial or annual plants that feature brightly colored blooms. They are part of the sunflower family and have flowers similar to sunflowers. The showy display attracts a wide range ofinsect pestswho like to munch on the plants; deer and rabbits are also attract...

After 90 days of incubation, results revealed a higher concentration of total Hg in the leaves than in the flowers or the stems. Plants that were grown in the soils with higher Hg concentrations showed significantly higher Hg uptake and translocation in the aboveground plant-biomass, and the ...
Petunia plants that experienced both competition from other plants in the container and lower irrigation rates had enhanced efficiency of flower production (i.e., more flowers per unit biomass). For Impatiens, however, the growing of single plants at "25% ETp" was plausible, but the addition ...
