Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
Such a "pollination syndrome", being due to flower color and orientation controlled by their genetics, ensures reproductive isolation and can be a cause of speciation. [25] Aquilegia petals show an enormous range of petal spur length diversity ranging from a centimeter to the 15 cm spurs of Aquilegia longissima.
Treatment of Botrytis involves cutting off the infected stock and clearing the surrounding area of A. majus from any of this debris. Pythium: Wilting in the plant may be caused by a Pythium species fungal infection if the plant is receiving adequate water. [1] Rust: Another fungal disease that A. majus is susceptible to is rust
Selfing syndrome refers to plants that are autogamous and display a complex of characteristics associated with self-pollination. [1] The term was first coined by Adrien Sicard and Michael Lenhard in 2011, but was first described in detail by Charles Darwin in his book “The Effects of Cross and Self Fertilisation in the Vegetable Kingdom” (1876), making note that the flowers of self ...
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
The flowers are visited by a wide variety of insects (the generalised pollination syndrome). [10] Some species in the insect order Lepidoptera frequently use the willowherb as their primary larval host-plant, examples including the elephant hawk moth ( Deilephila elpenor ), [ 11 ] bedstraw hawk moth ( Hyles gallii ), and the white-lined sphinx ...
This leads to shifts in pollination syndromes and to some genera having a high diversity of pollination syndromes among species, suggesting that pollinators are a primary selective force driving diversity and speciation. [5] [6] Ophrys apifera is an orchid species that has a highly evolved plant-pollinator relationship. This specific species ...
Symptoms include mosaic pattern on the leaves, malformed leaves and flowers, elongated shoots that are often red, and sometimes thorn proliferation. The distorted growth may be mistaken for herbicide damage. [12] There is no treatment for the disease, and control is limited to controlling the vector and destroying infected plants.
