Genome size in wild Pisum species

Theoretical and Applied Genetics, 1996
Genome size was measured in 75 samples of the wild pea species Pisum abyssinicum, P. elatius, P. fulvum and P. humile by ethidium-bromide (EB) flow cytometry (internal standard: Triticum monococcum) and Feulgen densitometry (internal standard: Pisum sativum 'Kleine Rheinländerin').

Geographic distribution of wild potato species

American Journal of Botany, 2001
The geographic distribution of wild potatoes (Solanaceae sect. Petota) was analyzed using a database of 6073 georeferenced observations. Wild potatoes occur in 16 countries, but 88% of the observations are from Argentina, Bolivia, Mexico, and Peru. Most species are rare and narrowly endemic: for 77 species the largest distance between two observations ...

Cocaine distribution in wild Erythroxylum species

Journal of Ethnopharmacology, 2006
Cocaine distribution was studied in leaves of wild Erythroxylum species originating from Bolivia, Brazil, Ecuador, Paraguay, Peru, Mexico, USA, Venezuela and Mauritius. Among 51 species, 28 had never been phytochemically investigated before. Cocaine was efficiently and rapidly extracted with methanol, using focused microwaves at atmospheric pressure ...

Wild bees in urban grasslands: Urbanisation, functional diversity and species traits

, 2020
While cities are known as important habitats for wild bees, a conceptual understanding of how assemblages of wild bee species are shaped by urban environments is limited.

Discovery of Wild Triticum Species

2020
As mentioned above, as early as in 1833, Link found a wild plant similar to T. monococcum in the Balkans and Asia Minor. He named it as Crithodium aegilopoides Link. In 1854, Balansa found the same wild wheat in Mt. Sipylus, Syria, Iraq, and Iran in Asia Minor. They were merged into Triticum and changed to T. aegilopoides (Link) Bal. E. Boissier (1853)

Utilization of Wild Species

1992
Wild species have been exploited most often as sources of biotic and abiotic stress resistance. Several varieties of wheat, oat, rice, potato, tomato, sunflower, okra, crucifers, tobacco, snapbean, and maize carry the genes for resistance introgressed from the distant species and related genera at some stage and thus surviving in the field.

Climate Change and Wild Species

2013
Climate has varied on geological timescales, and ecological systems have responded. Atmospheric CO2 has increased 36% and methane ~160% since the beginning of the Industrial Revolution (~1750), resulting in the globe warming ~0.85°C. Species are responding by rearranging their ranges.

Conservation of wild Lilium species

Biological Conservation, 1974
Abstract This review considers the question of whether nature reserves are of practical value to horticulture, using the case of lily culture. In both agriculture and horticulture there is a constant readjustment with Nature to conquer diseases, create new plant forms, or adapt the existing cultivated forms to special conditions of soil, climate, and

Effects of pre-breeding wild species on tuberization ofSolanum tuberosum haploid-wild species hybrids

American Potato Journal, 1989
Methods for incorporation of wild species germplasm intoSolanum tuberosum must be developed to efficiently utilize their desirable traits. This study was conducted to determine whether wild species selected for tuberization under long-day conditions produce haploid-species hybrids that tuberize better than hybrids with unselected species parents ...

Evaluation of tuber traits of 10,2x(2EBN) wild species through haploid × wild species hybrids

American Potato Journal, 1989
The wild species of potato do not tuberize under long day conditions making evaluation of their tuber characteristics difficult. HaploidTuberosum × wild species hybrids provide a means of evaluating the tuber characteristics of the 2x, wild species. Seventy-eight haploid × wild species hybrid families were evaluated for yield, specific gravity, percent
