Peptide alcohols as promoters of nitrate and ammonium ion uptake in plants.
نویسندگان
چکیده
Several aryl-carbamoyl dipeptide alcohols increased the uptake of nitrate and ammonium ions into corn root segments by up to 50% and 90%, respectively. The most effective one was N-carbobenzoxy-l-prolyl-l-valinol. Foliar application of this compound to underfertilized corn plants caused an increase in the rate of plant growth in the greenhouse and provided modest (6-10%) corn yield increases in field tests in Delaware.

Ammonium nitrate as an efficient and green reagent for the oxidation of alcohols into their corresponding carbonyl compounds in the presence of heteropoly acids
Simple, cheap and green protocol for effective conversion of alcohols to corresponding carbonyl compounds in the presence of H14[NaP5W30O110] and ammonium nitrate is reported. The products were characterized by FT-IR and comparison of their physical properties with those reported in the literatures. The progress of the reaction was monitored by thin layer chromatography (TLC) technique. The ali...

متن کاملAmino acids and nitrate as signals for the regulation of nitrogen acquisition.
The uptake of nitrogen (N) by roots is known to change with supply in a manner that suggests that the N status of plants is somehow sensed and can feedback to regulate this process. The most abundant source of N in soils for crops is nitrate. Uptake systems for nitrate, ammonium, and amino acids are present in the roots of most plants including crops. As nitrate is assimilated via conversion to...

Catalytic amount of Ce(IV) as ceric triethylammonium nitrate (CTEAN) in dichloromethane or acetone can bring about an efficient tetrahydropyranylation of different types of alcohols to afford the corrsesponding tetrahydropyranyl ethers in high yields. Deportection of tetrahydropyranyl ethers can also be achieved efficiently in the presence of this catalyst in methanol.
