Growth characteristics, oxygen exchange, and carbohydrate and chlorophyll contents were determined 30 days after subculturing of single node-derived plantlets of Solanum tuberosum cv Haig cultivated in vitro. Cultivation conditions were: (a) photomixotrophy in closed vessel, (b) photomixotrophy in closed vessel on medium supplemented with silver thiosulfate, (c) photomixotrophy in aerated vesse...

The objective of the study was to determine whether Parkia platycephala families with superior morphophysiological traits perform consistently across four stages early development (plantlets, seedlings, and juveniles at 34 60 months), as a means assess possibility conducting pre-selection. For 21 traits, following genetic parameters were estimated: heritability, coefficients variation (genetic,...

The plant tissue culture procedures for asexual multiplication of Hancornia speciosa represent an important process facilitating the preservation selected genotypes this threatened species and large-scale production plantlets population reinforcement or other utilization. However, there is no research regarding somaclonal variation at molecular level. This study aimed to evaluate role in geneti...

Polyploid plantlets, including triploid, tetraploid, and mixoploid, were induced from the European pear (Pyrus communis L.) cultivar ‘Fertility’ by in vitro colchicine treatment of leaf explants. The leaf explants were incubated in 0.4% (w/v) colchicine for 24, 48, or 72 h, then transferred to adventitious shoot-induction medium. Regenerated shoots were pre-selected according to their morpholog...

To obtain a suitable explant and efficient culture medium for plant regeneration in spinach, two cultivars of Melody and Karaj local seedlings were chosen. A hypocotyl and cotyledon segments as well as shoot tip explants were dissected from seedlings. The explants were then cultured on MS medium supplemented with IAA, GA3, NAA, and BAP and their response to this media was studied. A completely ...

Cadmium (Cd) is easily absorbed by the root system in many plant species and due to its solubility in water and toxicity is considered as a major pollutant. The aim of this study was investigation of cadmium toxicity on some physiological characteristics of lentil seedlings. So, two-week-old plantlets were treated with different concentrations (0 as control, 0.125, 0.25, 0.5, 1, 2.5 and 5 μM...
