Tobacco plants can use nitrogen taken up before mechanical wounding to synthesize nicotine afterwards

Grafting to improve nitrogen-use efficiency traits in tobacco plants

Nitrate plays a major role in the yield and quality of tobacco plants. This work explored the nitrogen-use efficiency (NUE) and how it can be affected by grafting. Two experiments were designed: in the first, using six commercial tobacco cultivars, the best cultivar for the NUE was selected and analysed for foliar NO3− content, total N, nicotine and nitrate reductase (NR) activity. The results ...

Tobacco & Nicotine - nicotine as therapy

Can nicotine use alleviate symptoms of psoriasis?

Psoriasis is a common chronic skin disorder with an estimated prevalence in the United States of 2.5% in white individuals and 1.3% in African Americans.1 Although psoriasis can manifest at any age, there seem to be 2 peaks in onset: one between the ages of 20 and 30 years, and another between the ages of 50 and 60 years.2 Several clinical types of psoriasis have been described; however, 90% of...

Nitrogen Transformations in the Tobacco Float Tobacco System

In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...
