بابونه شفاف یا anthemis hyalinedcیکی از مهم ترین گیاهان دارویی بوده که اسانس آن در صنایع مختلف داروسازی وآرایشی-بهداشتی مورد استفاده قرار می گیرد. مطالعاتی در زمینه کشت بافت این گونه از بابونه صورت نگرفته است و با توجه به خصوصیات دارویی و ترکیبات اسانس بابونه شفاف، مطالعات کشت درون شیشه این گیاه می تواند دارای اهمیت باشد. در این مطالعه تأثیر سطوح مختلف هورمون های گیاهی نفتالین استیک اسید(0 ، 1/...

An efficient protocol for callus induction and somatic embryogenesis of Cyclamen premium Mill. Was developed. In this study we investigate difference between response of two explants type leaf and petiole and two medium salt concentrations MS and 1⁄2 MS on callus percentage and somatic embryo number. Media was non-significant on callus production but leaf explants was better than petiole and in...

The rapid direct and repetitive somatic embryogenesis in Coffea arabica and C. canephora genotypes was tested on Murashige and Skoog medium (MS) containing thidiazuron (TDZ) (1-phenyl-3-(1,2,3,-thiadiazol-5-yl)urea) in concentrations of 2.27–11.35s M. Segments taken from cotyledon leaf, first leaf and stalk of regenerated plantlets produced clusters of somatic embryos directly from cut portions...

present study was conducted to consider the effects of different concentrations of 2,4-d and ba on somatic embryogenesis induction, development and maturation of three strawberry cultivars (kurdistan, parose and camarosa). for this purpose, leaf blade, nodal, petiole, stamen and flower bud calli were cultured on murashige and skoog (ms) medium supplemented with 2, 4 dichlorophenoxyacetic acid (...

The Tungkal Composite of liberica coffee rejuvenation program at Jambi Province is urgently needed due to the latest status plants are old and showing diseased attacked. To support rejuvenation, provision seedlings could be done by tissue culture approach through somatic embryogenesis. This research aimed study effect 2,4-D, BA TDZ on callus formation embryo induction from leaf explants. Explan...

BACKGROUND AND AIMS Understanding the fate and dynamics of cells during callus formation is essential to understanding totipotency and the mechanisms of somatic embryogenesis. Here, the fate of leaf explant cells during the development of embryogenic callus was investigated in the model legume Medicago truncatula. METHODS Callus development was examined from cultured leaf explants of the high...

Clerodendrum pholomidis is an important medicinal plant of Lamiaceae. Leaves, internode and petiole explants were cultured on Murashige and Skoog (MS) medium supplemented with combinations of 2, 4-dichlorophenoxy acetic acid (2, 4-D), kinetin (kn) and indole-3 butyric acid (IBA). Leaf explants formed clusters of globular somatic embryos directly from epidermal cells within 12-15d when cultured ...

This paper describes a protocol for the efficient vegetative propagation of Cleome rosea by somatic embryogenesis. Leaf and stem explants from nursery-grown seedlings of C. rosea were cultivated on Murashige and Skoog (MS) medium supplemented with indole-3-acetic acid (IAA), α-naphthaleneacetic acid (NAA), 4-amino-3,5,6trichloropicolinic acid (picloram) or 2,4-dichlorophenoxyacetic acid (2,4-D)...

Somatic embryogenesis is an efficient micro-propagation technique, which can lead to mass multiplication of tea with a tap root. Hence, the development viable somatic and protocol through liquid culture conditions needed increase efficiency protocol. Cotyledon-derived embryos, leaf stem callus TRI 5001 cultivar, were tested different MS media. A significantly higher cotyledon-derived embryo rat...

To obtain a higher percentage of callogenesis and consequently the maximum number of plantlets, one of the most important procedures for transgenic plant production. To this end, a factorial experiment using completely randomized design (CRD) with four replications was carried out to assess the effect of cultivar (Marfona and Agria), type of explants(leaf and internode), Kanamycin concentration...
