Inbreeding in horsenettle (Solanum carolinense) alters night-time volatile emissions that guide oviposition by Manduca sexta moths.
Plant volatiles serve as key foraging and oviposition cues for insect herbivores as well as their natural enemies, but little is known about how genetic variation within plant populations influences volatile-mediated interactions among plants and insects. Here, we explore how inbred and outbred plants from three maternal families of the native weed horsenettle (Solanum carolinense) vary in the ...
متن کاملStudy of Variation of Yield and Morphological Traits of Some Local Varieties of Iran’s Eggplant (Solanum melongena L.)
Eggplant is a crop that has been cultivated for a long time in different areas of Iran. Nevertheless, no sufficient studies have been done on variation of morphological traits and yield of this crop in Iran, and it has not been well-attended in breeding programs. Therefore, to study genetic diversity in collected local varieties, the experiment was conducted in a Randomized Complete Block Desig...
متن کاملThe role of male flowers in andromonoecious species: energetic costs and siring success in Solanum carolinense L.
Two non-mutually exclusive hypotheses regarding the benefits of andromonoecy (producing perfect and female-sterile flowers on the same plant) are tested using Solanum carolinense. Results indicate that (1) staminate flowers are cheaper to produce than perfect flowers, even after correcting for their relative position in the inflorescence; (2) the resources saved by producing staminate flowers a...
متن کاملMorphological variation and Taxonomic validation of gill raker characteristics in Caspian marine shad (Clupeidae: Alosa braschnikowi)
We used 50 specimens of Alosa braschnikowi (A. brschnikowi) to study the growth effect on Gill raker morphology. Gill rakers counted as 26-47 which increased in relation to increase in TL (P<0.05). Gill raker lengths and the length:width ratio decreased with a high coefficient of relationships (R2=0.818 and 0.634 subsequently) regarding the increase of TL. The proportion of gill raker length to...
متن کاملInsect herbivores, density dependence, and the performance of the perennial herb Solanum carolinense.
How insect herbivores affect plant performance is of central importance to basic and applied ecology. A full understanding of herbivore effects on plant performance requires understanding interactions (if any) of herbivore effects with plant density and size because these interactions will be critical for determining how herbivores influence plant population size. However, few studies have cons...
