Encapsulation-dehydration and PVS2-vitrification cryopreservation protocols were evaluated for the long-term conservation of a diverse group of Rubus germplasm. Cold acclimation for a 4-week period prior to cryopreservation was necessary for regrowth of shoot apices from blackberry and raspberry genotypes. For the encapsulation-dehydration protocol, encapsulated apices were pretreated in 0.75 M...
Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...
Highly efficient in vitro regeneration system has been developed for Swertia lawii Burkill, an important herb used as substitute for Swertia chirayita. Shoot tips explants were cultured on MS medium with various phytohormones for multiple shoot production. The best shoot production frequency (100%) and maximum shoots (10.4 ± 0.8) were obtained on MS media containing TDZ (3.0 mg l-1) in combinat...
alpha,alpha-Trehalose induced a rapid blackening of the terminal 2.5-centimeter region of excised Cuscuta reflexa Roxb. vine. The incorporation of radioactivity from [(14)C]glucose into alkali-insoluble fraction of shoot tip was markedly inhibited by 12 hours of trehalose feeding to an excised vine. This inhibition was confined to the apical segment of the vine in which cell elongation occurred...
This study describes the standardization of an efficient in vitro propagation and hardening procedure for obtaining plantlets from shoot tips of Hemp (Cannabis sativa L.). Hemp seedlings were germinated on half-strength 1/2 MS medium supplemented with 10 g·Lsucrose, 5.5 g·Lagar at a pH of 6.8 under light for 16 h per day. MS medium containing 0.2 mg·LTDZ, 0.1 mg·LNAA supported the maximal auxil...
Citrus genus is known as one of the world's major economic agricultural products. In the current research, a method is reported for artificial seed production technology by shoot tips in Citrus sinensis.var. Thamson navel. Alginate is one of the most efficient gelling agents in the production of capsule coating in artificial seeding technique. In the current research, impact of different consti...
Lycopodiophyta-consisting of three orders, Lycopodiales, Isoetales and Selaginellales, with different types of shoot apical meristems (SAMs)-form the earliest branch among the extant vascular plants. They represent a sister group to all other vascular plants, from which they differ in that their leaves are microphylls-that is, leaves with a single, unbranched vein, emerging from the protostele ...
