Endogenous hormonal status of embryogenic callus in cocos (Cocos nucifera L.) explants
(1996-01-01)
The application of optimum concentrations of hormones according to specific culture stages plays an important role, especially in plants which are concerned lo be recalcitrant for propagation in vitro, like Cocos nucifera ...
Mode of action of plant hormones and plant growth regulators during induction of somatic embryogenesis: molecular aspects
(2005-11)
Plant hormones play critical roles in the establishment of somatic embryogenesis. During this process, somatic plant cells reverse their state of differentiation, acquire pluripotentiality and set up a new developmental ...
Effect of macronutrients and sucrose concentration on in vitro growth of Drosera capensis L. (Droseraceae) plants, and evaluation of six substrates for acclimatization
(2011-01)
The effect of two concentrations of the Murashige and Skoog macronutrients (full and half strength), in combination with three concentrations of sucrose (1.5, 3.0 and 4.5% w/v), was evaluated on the in vitro growth of ...
Hormonal status of maize initial explants and of the embryogenic and non-embryogenic callus cultures derived from them as related to morphogenesis in vitro
(2001)
Endogenous hormone levels (indole-3-acetic acid [IAA], abscisic acid [ABA], gibberellins 1, 3 and 20 [GAs], zeatin/zeatin riboside [Z/ZR] and N6[Δ2-isopentenyl] adenine/N6[Δ2-isopentenyl] adenosine; [iP/iPA]) were analysed ...
