Liquidambar styraciflua L. seedlings and tissue-cultured plantlets were grown under high, medium, or low (315, 155, or 50 microeinsteins per square meter per second photosynthetically active radiation) quantum flux densities. Net photosynthesis, chlorophyll content, and chloroplast ultrastructure of leaves differentiated from these conditions were investigated. Seedling photosynthetic rates at ...

in order to study, in vitro bud induction and shoot regeneration of different explants (shoot tip, axillary bud, hypocotyl and cotyledon) of henbane on ms medium enriched with various concentrations of kinetin (0, 1, 3 and 5 mg.l-1) alone or in combination with indole-3 acetic acid (0, 0.1 and 0.5 mg.l-1) this research was investigated in urom zist tak knowledge-based company plant tissue cultu...

Tripleurospermum insularum (Asteraceae) is a critically endangered (CR) insular endemic species in Turkey and facing high risk of extinction. Here, rapid efficient vitro propagation protocol using nodal segments obtained from seedling shoots cultured on Murashige Skoog (MS) basal medium supplemented with different plant growth regulators (PRGs) was developed to conserve T. insularum. Besides, t...

Rooted quivers are quivers that do not contain A∞ ≡ ··· → • → • as a subquiver. The existence of flat covers and cotorsion envelopes for representations of these quivers have been studied by Enochs et al. The main goal of this paper is to prove that flat covers and cotorsion envelopes exist for representations of A∞. We first characterize finitely generated projective representations of A∞. We ...

7 An antimatroid is a family of sets such that it contains an empty set, and it is accessible and closed under union of sets. An antimatroid is an ‘antipodal’ concept of matroid. 9 We shall show that an antimatroid is derived from shelling of a poset if and only if it does not contain a minor isomorphic to S7 where S7 is the smallest semimodular lattice that is not 11 modular. It is also shown ...

In this study, an in vitro propagation protocol of Poncirus trifoliata L. (Raf.) rootstock, which is one the main rootstocks used citrus, was created. Monocular node parts plant, source explant, were cultured MS nutrient media containing BAP at dissmilar concentrations (0.5-1.0-2.0 mg/l). Afterward, it observed that shoot appearance and tillering achieved explants medium comprising 1.0 mg/l BAP...

An efficient protocol for plant regeneration has been developed for crop improvement programs. The present study was designed to assess the regeneration response of cotyledonary node explant taken from the germinating seeds of peanut (Arachis hypogaea L.). Complete plants were regenerated from in vitro cultured sectioned cotyledonary nodes. Multiple shoots arose on 6-benzylaminopurine (BAP) sup...

The aim of our study was to consider the efficiency of randomly amplified polymorphic DNA (RAPD) analysis to show the differences between Rhododendron mutants and control plants. The mutant plantlets were selected due to their better In vitro shoot and root regeneration relative to control in both varieties. Six mutant plantlets from Alfred and seven mutant plantlets from Paars variety were sel...

The midto long-term preservation of papaya (Carica papaya L.) would allow for the safeguarding of important germplasm. In this study, soft friable callus (SFC) and hard callus (HC) were induced from the first two true leaves of 10-day-old seedlings containing a midrib derived from the germinated seed of two cultivars (‘Rainbow’ and ‘Sunrise Solo’). Following germination on a Murashige and Skoog...

Tylophora indica Burm F. Merrill. is widely used against various diseases owing to the presence an array of medicinally important secondary metabolites. Its stem is bitter, stomachic, stimulates bile secretion, enriches the blood and cures diseases like diabetes, fever, flatulence, hypertension, jaundice, leucorrhoea, urinary disease and upper respiratory tract infection. It is neglected for ti...
