The Effect of Caffeine and Trifluralin on Chromosome Doubling in Wheat Anther Culture

Plants, 2020
Challenges for wheat doubled haploid (DH) production using anther culture include genotype variability in green plant regeneration and spontaneous chromosome doubling. The frequency of chromosome doubling in our program can vary from 14% to 80%. Caffeine

Rate and time of nitrogen fertilizer application for winter camelina

Agronomy Journal, Volume 116, Issue 4, Page 1804-1816, July/August 2024.
Abstract Winter camelina [Camelina sativa (L.) Crantz] is a potential third crop to diversify maize (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations in the upper Midwest. Although generally considered a low‐input crop, empirical evidence suggests that it responds to added nitrogen (N) fertilization.

Simultaneous removal of mixed pesticides and natural organic matter from surface waters by nitric and chlorosulfonic acid functionalized powdered activated carbon

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 7, Page 1646-1659, July 2024.
Abstract BACKGROUND Several studies have addressed the adsorption of pesticides such as alachlor, acetochlor, metolachlor and fenthion from water and wastewater, yet the interaction of these compounds with natural organic matter (NOM) complicates their effective removal owing to competitive adsorption effects.

Grain yield and quality responses to nitrogen application rate and timing in dry direct broadcast seeded rice under different weather conditions

Agrosystems, Geosciences &Environment, Volume 7, Issue 2, June 2024.
Abstract In rice (Oryza sativa L.) production, dry direct seeding is one of the most essential technologies to reduce labor input and to increase net income. Field experiments were conducted in southwestern Japan in 2019 and 2020 to determine the effects of nitrogen (N) application rate and timing on grain yield, lodging, grain appearance, and protein ...
