The present paper describes some effects of light intensity and temperature on non-fruiting growth of a grape-vine variety, normally grown in warm regions, using controlled environment growth cabinets.
At 13 weeks the plants were harvested and dry weights of roots, parent canes, stems, and leaves measured.
Finding include that dry weights increased with increasing light intensity, apical dominance increased with increasing temperature and intemode length was stable under all conditions.
