Flue‐cured tobacco response to sublethal rates of glufosinate
نویسندگان
چکیده
Abstract Glufosinate is a broad‐spectrum, contact herbicide that currently applied to genetically engineered row crops tolerate exposure the compound. Flue‐cured tobacco ( Nicotiana tabacum L.) susceptible glufosinate, yet it commonly grown in close proximity tolerant North Carolina. The impact of glufosinate drift on flue‐cured not known. Research was conducted Carolina test effects sublethal rates (0.270, 0.135, 0.067, 0.034, 0.017 lb a.i. acre –1 ) injury, yield, visual quality, financial value, and leaf chemistry. Simulated imposed approximately 5 wk after transplanting. Visual injury increased with rate ranged from 15 83% 10 1 2 treatment, respectively. Cured yield reduced by 45% at highest exhibited linear decline 47 for every 0.01 . quality per value were affected most likely due loss necrotic tissue late‐season plant growth compensation. Residues green cured leaves likewise detected. Producers commercial applicators should exercise caution when applying around because can result physical spray drift, as well inability sell has been exposed pesticide labeled application.

Chemiluminescent response of grass carp (Ctenopharyngodon idella) was assessed to determine the effect of various concentrations of diazinon on the phagocytosis of grass carp in order to evaluate the fish immunity after exposure to this toxic chemical. One hundred and twenty specimens with individual weight of 850±155g were exposed to various concentrations of diazinon at 1, 2 and 4mg/L provide...

متن کاملChanges of major wall polysaccharides and glycoproteins of tobacco cells in response to excess boron
Effects of excess concentrations of boron on major cell wall components of tobacco cells(Nicotiana tabacum L. cv. Burley 21) were studied. Pectin, xyloglucan, hydroxyproline-richglycoproteins (extensin), and arabinogalactan proteins were characterized. Results showedthat increased boron supply resulted in significant decrease in cell and cell wall dry weights.Also, high concentrations of boron ...
