Wild Carrot

This summary of biological data is for wild carrot, Daucus carota L. ssp. carota, as a weed in Canada, particularly in central Ontario. Brief reference is made to wild carrot in Europe and to the related cultivated carrot which have many pests in common. Weedy populations of this biennial occur in areas formerly occupied by deciduous forests in eastern Canada, and by the coastal Douglas fir forest in British Columbia. It belongs to association of plants of roadsides, old pastures and open spaces which are disturbed periodically.

This summary of biological data is for bird’s-foot trefoil, Lotus corniculatus L., which is weedy in Canada, particularly in eastern Canada and the Fraser valley of British Columbia. Bird’s-foot trefoil is an agricultural escapee and is often continuous over large areas of roadside and waste places. It can be controlled by the use of several common herbicides.

The elemental composition of the protein bodies from several members of the Umbelliferae including carrot (Daucus carota L. cv. Imperator 408), wild carrot (Daucus carota L.), caraway (Carum carvi L.), anise (Pimpinella anisum L.), dill (Anethum graveolens L.), celery (Apium graveolens L. cv. Tall Utah), fennel (Foeniculum vulgare Mill.), parsnip (Pastinaca sativa L. cv. Hollow Crown), parsley (Petroselinum sativum L. cv. Moss Curled), and chervil (Anthriscus cerefolium L. cv. Curled) was determined using energy dispersive X-ray analysis. Globoid crystals in the endosperm usually contained P, K, and Mg or infrequently P, K, Mg, and Ca. In the embryos of carrot and caraway, P was always present with a combination of K, Mg, or Ca. Calcium was the only element detectable in the calcium-rich crystals. The proteinaceous matrix always contained S and K regardless of the inclusion present in the protein body.Quantitative determinations of P, Mg, K, and Ca are presented for all members studied except wild carrot, chervil, celery, and fennel. In all species analysed in this manner K or Ca were present in the highest amounts followed by P and Mg. Calcium-localization studies showed that most of the Ca is located in the endosperm and pericarp portions of the mericarp.

Male-sterile carrot plants with petaloid-stamens were discovered in wild populations in the vicinity of Guelph, Ontario, Canada and inheritance of phenotype was assessed. Genetic analyses were also conducted to identify nuclear restorer genes of petaloid cytoplasmic male sterility (CMS) from wild carrot, and determine if Guelph, Cornell and Wisconsin cytoplasmic male-sterile accessions interacted similarly with alleles of restorer genes from different sources. Petaloid male-sterility was inherited cytoplasmically for the new Guelph accessions, and nuclear genotypes which normally produce `green' or `white' petaloid-stamens in combination with the Cornell cytoplasm also produced corresponding phenotypes when backcrossed to Guelph cytoplasmic accessions. Two duplicate restorer genes were identified from wild carrot. Dominant alleles of single restorer genes from three sources, one from wild carrot and two from cultivated germplasm, restored stamen production to Guelph, Cornell and Wisconsin petaloid cytoplasmic accessions, suggesting that the cytoplasms were genetically identical.

Vicia Cracca

This paper provides a summary of biological data on five weedy species of vetch (Vicia). All species are naturalized in Canada and are found in a wide range of habitats with their main centers of distribution in Eastern Canada and the south and coastal regions of British Columbia. Vicia cracca is the most common and serious problem and occurs nationwide. Vicia sativa is the most variable of the species; numerous subspecies, varieties, forms and hybrids are described. Tendrils allow vetches to attach to crop plants and form mat-like infestations. Vetch species are sensitive to a number of herbicides but there appears to be differential tolerance among species to chlorthal dimethyl, 2,4-DB and others. Vicia spp. are host to several economically important pathogens and parasites.Key words: Weed biology, vetches, Vicia spp., distribution

This paper provides a summary of biological data on Stellaria media (L.) Vill., commonly known as chickweed. It is found throughout most of the world and is present in all Canadian provinces and both territories, being particularly abundant in British Columbia and eastern Canada. Chickweed is a weed of grain fields, young pastures, lawns, and gardens, and can be controlled by the use of several common herbicides.
