The Effects of Ph Levels and Plant Growth Regulators on in vitro Regeneration of Almond (Prunus dulcis Mill.)
نویسنده
چکیده
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 the shoots. NAA treatment gave friable callus and IBA produced compact callus. Between two types of auxins used only shoots treated with IBA produced roots. PH levels had significant effect on rooting. The shoots of ‘Shahrood 8’ produced roots at pH 5.7 in the rate of 70%. And the shoots of ‘Shahrood 10’ generated roots at pH 4.8 at the rate of 60%.

An efficient regeneration and rapid micropropagation protocol for Almond using dormant axillary buds as explants.
An efficient in vitro protocol was standardized for Almond (Prunus dulcis) propagation using dormant axillary buds as explants. Explants were cultured on Murashige and Skoog (MS) and woody plant medium (WPM) supplemented with different concentration/combination(s) of phytohormones. MS basal medium showed lowest shoot induction and took longest duration for shoot initiation. Multiple shoots were...
متن کاملRegulation of Nitrogen Uptake at the Whole-plant Level: A Study in Almond Trees
It has been proposed that a pool of amino N, whose size is determined by aboveground N demand, cycles in the plant and regulates soil N uptake by exerting an inhibitory effect at the root level. Several experiments were carried out to study this hypothesis in almond trees [Prunus dulcis (Mill.) D.A. Webb]. Based on the evidence found, there is an association, at the whole tree level, between sa...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...
متن کاملAssessment of the Genetic Diversity of Almond (Prunus dulcis) Using Microsatellite Markers and Morphological Traits
The genetic diversity among 56 almond (Prunus dulcis) genotypes was analysed using 35 microsatellite markers and 14 morphological traits. Analysis of morphological traits revealed a wide range of variation among the studied genotypes. Out of 35 simple sequence repeats (SSRs) markers, 25 were polymorphic, producing 215 alleles that varied from 2 to 16 with an average of 8.76 alleles per locus. R...

Salicornia europaea is a halophytic annual plant of the Chenopodiaceae family, which is considered as an oil plant in marine irrigation. This experiment was conducted to determine the effect of salinity and to reach the best hormonal treatment for shoot regeneration. After washing and sterilization, seeds of S. europaea were cultured under controlled light and temperature conditions at five sal...
