Haploid plants of Nicotiana tabacum L. were produced in greater numbers from anthers on agar medium containing activated charcoal than on the same medium without charcoal.
Incorporating activated charcoal (AC) in culture media has been shown to affect growth and development of various organisms. Since AC stimulates the development of tobacco haploid plantlets from cultured anthers, research was conducted to determine the effect of activated charcoal on pith-derived
Tobacco plant was known to be a non-fructan-storing plant. However, we demonstrated that fructo-oligosaccharides (FOSs) were formed in cured tobacco leaf on adding sucrose to the leaf in our previous report (Nagai et al., J. Agric. Food Chem., 60, 6606-6612, 2012). Also, it was expected from the
BACKGROUND
Since 1962, the tobacco variety Nicotiana tabacum cv. Bel-W3 has been used worldwide as an ozone (O3) bio-indicator. The use of indicator plants to monitor O3 pollution has proven problematic when trying to correlate the severity of injury to ambient O3 concentration. The aim of the
Araujia sericifera Brot. (Fam. Apocynaceae) is an evergreen climbing plant native of South America, originally introduced in Europe as an ornamental. In spring 2012, virus-like symptoms including bright yellow mosaic of calico-type and leaf distortion were observed in three A. sericifera plants
In winter 2012, some potted plants of African daisy (Arctotis × hybrida L., family Asteraceae) cv. Hannah, propagated by rooted stem cuttings and cultivated for commercial purposes in a greenhouse located at Albenga (Liguria region, Italy), were noticed for a rapid dieback, generalized reddening,
