MEIOTIC STUDIES OF SOME AVENA SPECIES AND POPULATIONS IN IRAN
Eleven populations of five Avena species were analysed for meiotic characters including chiasma frequency and distribution as well as chromosomal association and segregation. Plants of a single population of A. eriantha showed the presence of 2n = 14 (diploid) and 2n = 4x = 28 chromosome number. Populations of A. barbata and A. wiestii possessed n = 14, while populations of A. sterilis ssp. lud...
متن کاملSalinity stress enhances production of solasodine in Solanum nigrum L.
Various in vitro grown tissues (non-regenerative callus, regenerative callus and microshoot derived leaves) of Solanum nigrum L. were cultured under salinity stress (0-150 mM NaCl) for enhanced production of solasodine, a steroidal alkaloid and an alternative to diosgenin, which is used as a precursor for the commercial production of steroidal drugs. The role of plant growth regulators and vari...
متن کاملStudies on phytochemical constituents and antimicrobial activities of leaves, fruits and stems of Solanum nigrum L
Medicinal plants are being used as traditional medicines to cure several infectious and non-infectious diseases because of their products are safe in contrast to the synthetic medicines that are considered as unsafe to human including other animals and environment. We selected Solanum nigrum L. (Makoi) which belongs to family Solanaceae to evaluate antimicrobial activities against six pathogeni...
متن کاملAntimicrobial activity of fruits of Solanum nigrum and Solanum xanthocarpum.
Current study was conducted to investigate antimicrobial activity of fruit extracts of two Solanaceous plants (Solanum nigrum and Solanum xanthocarpum) found in Pakistan. Petroleum ether, chloroform, dichloromethane, ethyl acetate, acetone, methanol and water were utilized for extraction. The highest percentages of polar components of both the species were extracted by water; little amount of n...
