Nicotiana glauca Grah. is a species native of Southamerica which belongs to the Solanaceae Family. In Spain it naturally grows in arid areas close to the seaside in the Southeast and Canary and Balearic Islands. Its adaptation to regions with low rainfall, sprouting capacity and high sugars contents in the stems, are the most remarkable features. The biomass production, sugars content and sprouting capacity under 4 hydric regimes and 2 different cutting conditions, were studied in an experimental field. The hydric regimes were: 200, 240, 400 and 600 mm/year. Productions with 1 cut/year (December) and 2 cuts/year (August and December) were compaired when plants were cut down at soil level. Productivities ranged from 1.5 to 5.1 tons of dry matter per hectare and year, the ones corresponding to 1 cut/year being always higher. Clear differences in sugars distribution along stems were not observed. The average sugars content was 23. ABSTRACT. over dry weight. The sprouting capacity fluctuated between 67.

The obtained yields lead into thinking of Nicotiana glauca Grah. as a possible perennial energy crop of high interest for warm arid areas with mild winters. RESULTS AND DISCUSSION. CONCLUSIONS.
