An efficient protocol has been developed for regeneration of complete plants through somatic embryogenesis in H. coronarium. Creamish white, pale yellow and brown calli were obtained on MS medium supplemented with different concentrations of auxins [2, 4-Dichlorophenoxy acetic acid (2, 4-D), Indole-3 acetic acid (IAA) and 1-Naphthylacetic acid (NAA)] after 4 weeks. Creamy white calli developed ...

The in vitro biocontrol ability of Trichoderma harzianum on the phytopathogen Alternaria alternata improved in the presence of the growth regulators gibberellic acid (GA3), or indolacetic acid (IAA) or benzylaminopurine (BAP) or foliar nutrient at concentrations similar or higher than those used at the field level. These plant hormones decreased the secretion of endopolygalacturonase (endo-PG) ...

6-Benzylaminopurine is a broad-spectrum plant growth regulator, able to rejuvenate plants, bring plants out of dormancy, cause the formation lateral shoots and root shoots, stimulates chlorophyll positively affects photosynthesis, making leaf darker greener, stronger, in many crops are able, with out-of-root processing green fruits berries, somewhat postpone ripening time favor size weight. The...

This study was conducted to observe the effects of exogenous gibberellic acid3 (GA3) and 6-benzylaminopurine (BAP) treatments on growth inflorescence initiation Phalaenopsis determine whether hormonal applications can substitute for low-temperature exposure floral transition. Queen Beer ‘Mantefon’ clones were treated with no hormones (control), GA3 100 mg/L, 200 BAP mg/L + by foliar spray. The ...
