The Effects of Ph Levels and Plant Growth Regulators on in vitro Regeneration of Almond (Prunus dulcis Mill.)
In this research, a factorial 4×3×4 with 4 replications in Completely Randomized design was used to study the effects of different auxin treatments (4 levels), pH(2 levels) and cultivars (3 levels) on regeneration and rooting of in vitro shoot tips excised from shoots cultured on media supplemented with 1.5-2 mg/l BA. The results showed both auxins (NAA and IBA) produced callus in the bases of ...
متن کاملAnatomy and cell wall polysaccharides of almond (Prunus dulcis D. A. Webb) seeds.
The anatomy of Prunus dulcis was analyzed by applying several differential staining techniques and light microscopy. Prunus dulcis seed has a thin and structurally complex seed coat, with lignified cellulosic tissue. The embryo has two voluminous cotyledons. Cotyledon cells have a high number of protein and lipid bodies, some of which have phytin. The provascular tissue, located in the cotyledo...
متن کاملIdentification of stylar RNases associated with gametophytic self-incompatibility in almond (Prunus dulcis).
Stylar proteins of 13 almond (Prunus dulcis) cultivars with known S-genotypes were surveyed by IEF and 2D-PAGE combined with immunoblot and N-terminal amino acid sequence analyses to identify S-RNases associated with gametophytic self-incompatibility (SI) in this plant species. RNase activities corresponding to Sa and Sb, two of the four S-alleles tested, were identified by IEF and RNase activi...
متن کاملDual role of imidazole as activator/inhibitor of sweet almond (Prunus dulcis) β-glucosidase
The activity of Prunus dulcis (sweet almond) β-glucosidase at the expense of p-nitrophenyl-β-d-glucopyranoside at pH 6 was determined, both under steady-state and pre-steady-state conditions. Using crude enzyme preparations, competitive inhibition by 1-5 mM imidazole was observed under both kinetic conditions tested. However, when imidazole was added to reaction mixtures at 0.125-0.250 mM, we d...
