MODELLING THE INTERACTION BETWEEN WILD AND CULTIVATED SPECIES.
… for the simulation of the interaction between cultivated and wild species. Biophysical models are powerful tools to analyze the interactions between plants and environmental variables as well as to optimize crop management. However, one of their main weakness is the lack of algorithms for …

Red rice competition and control in cultivated rice
Studies were conducted to evaluate rice competitiveness with red rice and how to utilize glufosinate- and imazethapyr-resistant rice in water-seeded rice to control red rice. In the interference study, CL 121, Cocodrie, Drew, and Jasmine were seeded to obtain 95, 190, and 290 plants/sq m. Red rice …

Analysis of Aroma Constituents in Cultivated Strawberries by GC/MS
… wild strawberries studied, but found only in few cultivated varieties. In this work, three kinds of cultivated strawberries were sampled and analyzed. The three strawberries all belong to the Camarosa variety. They came from different growing areas: Salinas (California), Orrville (Ohio), and …

Understanding Plant Pathosystems in Wild Relatives of Cultivated Crop Plants
… resistance traits that can be introgressed into cultivated crops. The identification of novel disease resistance is of paramount importance because pathogen co-evolution is not only defeating current resistance genes (R genes) but chemical controls as well. Phytophthora sojae (P. sojae), the …

Developing Serum-Free Media Via Bioprocessing For Cultivated Seafood Products
Global food production management has become a challenge with an anticipated population of 10 billion people by 2050 and the ongoing COVID-19 epidemic. Seafood is a vital food source due to its widespread consumption, excellent nutrient profile, and low feed conversion ratio, rendering its …

Denitrification and greenhouse gas emissions from cultivated and wetland alluvial soils
… organic C amendments on denitrification rates of cultivated lands and restored forested wetlands. N2O, CH4 and CO2 emissions from restored and natural forested wetlands were measured to determine if restoration for NO3 removal will increase greenhouse gas emissions, thereby contributing to global …

Effects of shade on the cultivated strawberry (Fragaria X anassa Duch.)
Greenhouse and field studies were conducted to determine the effects of shade on photosynthetic, growth and yield responses of "Redchief" strawberries. Plants were exposed to 0 , 30 , 47 and 63 percent shade in the greenhouse. Net photosynthesis (Pn) as measured under the shade treatments …

Effects of defoliation on the cultivated strawberry (Fragaria X ananassa Duch.)
Using 'Redchief' (Junebearer) and 'Tribute' (dayneutral) cultivars, greenhouse and field studies were conducted to determine the effects of defoliation on photosynthesis, growth and yield of the strawberry. From preliminary photosynthesis experiments it was found that both 'Redchief' and 'Tribute' …

Arsenic uptake by beets (Beta Vulgaris) cultivated in a roxarsone-contaminated medium
Arsenic (As) is a global toxicant that negatively impacts human health. Roxarsone (ROX) is an organoarsenical administered to poultry to control internal parasites. ROX is excreted from poultry unchanged and the waste may be used for vegetable fertilizer. This experiment was conducted with beets …

The effects of phenylbutazone on a strain of fibroblasts cultivated in vitro
<p>Phenylbutazone was first synthesized in 1946 by H. Stenzyl during his investigation on pyrazole and pyrazoline derivatives. Although these compounds had been studied during the previous fifty years, the pharmacological properties were only recently recognized. It has been used clinically since …

The use of Cicer reticulatum L. for genetic improvement of cultivated chickpea
… a range of agronomically important traits in cultivated chickpea. This study was conducted to evaluate the phenotypic and genetic variations of 486 lines derived from interspecific crosses between C. arietinum (CDC Leader) and 20 accessions of C. reticulatum. Field evaluations were done on the …
