Timing of seed dispersal in Daucus carota By: Elizabeth P. Lacey Lacey, E. P. (1982) Timing of seed dispersal in Daucus carota L. (Apiaceae)
This study describes the temporal pattern of seed dispersal in Daucus carota and examines the fate of seeds dispersed at different dates in SE Michigan. Plants varied greatly in both time of onset and rate of dispersal. Onset was directly related to flowering time, a phenotypically plastic character, and tended to occur earlier in newly established populations. Dispersal rate was similar for di...
متن کاملPatterns of Gene Flow between Crop and Wild Carrot, Daucus carota (Apiaceae) in the United States
Studies of gene flow between crops and their wild relatives have implications for both management practices for cultivation and understanding the risk of transgene escape. These types of studies may also yield insight into population dynamics and the evolutionary consequences of gene flow for wild relatives of crop species. Moreover, the comparison of genetic markers with different modes of inh...
متن کاملPervasive Mitochondrial Sequence Heteroplasmy in Natural Populations of Wild Carrot, Daucus carota spp. carota L
Exceptions to the generally accepted rules that plant mitochondrial genomes are strictly maternally inherited and that within-individual sequence diversity in those genomes, i.e., heteroplasmy, should be minimal are becoming increasingly apparent especially with regard to sequence-level heteroplasmy. These findings raise questions about the potential significance of such heteroplasmy for plant ...
متن کاملThe Sugars of the Roots of Daucus carota.
It is well known that some reducing substances, resembling true sugars in their behavior, occur almost invariably in plant extracts and may introduce great errors into the estimation of those sugars. Since the soluble sugars commonly present in plants (glucose, fructose, sucrose and maltose) are easily fermented by yeast, this phenomenon suggests itself as a convenient and practicable method fo...
متن کاملChemical composition and antioxidant activity of the essential oil and the methanol extract of Algerian wild carrot Daucus carota L. ssp. carota. (L.) Thell
In this study we identified the chemical composition and antioxidants effects of essential oils and methanolic extracts from (seeds and leaves) of wild carrot. A Total of 48 and 47 volatile compounds from the essential oils of leaves and seeds in D. carota L. subsp. carota, were identified by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). These compounds were mainly α...
