Stevia rebaudiana, which produces the non-caloric natural sweeteners referred to as steviol glycosides (SGs), is a perennial herb native to South America. This study examines the effect of various biotic elicitors, including chitosan (CH) and yeast extract (YE), as well one abiotic elicitor, namely methyl jasmonate (MeJA), on in vitro shoot multipl...
Although micropropagation in temporary immersion systems might increase plant growth and multiplication, it can also cause specific problems such as hyperhydricity and losses by contamination. A new commercial temporary immersion bioreactor, SETIS™, was used to micropropagate two Tunisian pear cultivars, ‘Arbi’ and ‘Mahdia 6’. The latter cultivar w...
The temporary immersion system SETIS™ consists of an upper recipient for in vitro plants and a connected lower recipient for liquid medium. The combination of periodical short immersion with nutrients and regular aeration of the headspace allows fast in vitro growth of a large number of plant species. Benefits and drawbacks of the system are discus...
A procedure was developed for in vitro propagation of Rosa genotypes along with an efficient de novo shoot organogenesis (DNSO) method. We tested, on one genotype (hybrid of Rosa wichurana), the effects of MS basal medium complemented with two growth regulators to achieve either shoot elongation or shoot multiplication of plants. These media were c...
The Mycelium Donor Plant system (MDP) was adapted to study the time course of the colonization of Pyrus communis by Rhizophagus irregularis under in vitro conditions. Isolated germinated spores did not colonize pear roots. Inoculum composed of R. irregularis spores/mycelium associated with chicory root fragments was used to inoculate Medicago trunc...

Worldwide, Hevea producers face the need to replant large surfaces in the coming years. The rubber yield per ha, produced by trees grafted on heterogeneous illegitimate seedling rootstocks, has reached its maximum. For long-standing Hevea clones, as for a lot of other tree species, one of the consequences of physiological aging is reduced in vitro ...
