Boron (B) plays a crucial role in plant physiological processes, and imbalances in its supply can markedly affect plant morphophysiology. This study evaluated the effects of a B concentration gradient on the growth and morphophysiological responses of Alternanthera tenella under in vitro conditions. Stem segments were cultured on media supplemented with different B concentrations (0, 125, 250, 500, 750, 1000, and 2000 µM) for...

In the in vitro cloning of specific individuals of woody species, a challenge can be the low viability of explants collected from old mature donor trees due to the recalcitrance of their plant material. Other factors, such as the auxin–cytokinin balance, must also be considered. We investigated how in vitro conditions and donor age can modulate the regeneration capacity, morphophysiology, and DNA methylation of Quercus robur ....
