iran is one of the main date (phoenix dactylifera) producing countries in the world. however, little information is available on the pollen viability and favorable storage conditions of iranian male date cultivars. this study was conducted to estimate the best in vitro pollen germination of three male date palm cultivars, `ghanami’, `samsmavi’ and `gheibani’ using various doses of boric acid (0...

Fecal samples play an important role in giant panda conservation studies. Optimal preservation conditions and choice of microsatellites for giant panda fecal samples have not been established. In this study, we evaluated the effect of four factors (namely, storage type (ethanol (EtOH), EtOH -20 °C, 2-step storage medium, DMSO/EDTA/Tris/salt buffer (DETs) and frozen at -20 °C), storage time (one...

In micropropagation of lily, preferably bulblets should be produced: Because bulblets are compact and robust, they are much easier to handle and to plant in soil than shoots. In this review, the various factors that determine bulblet growth in vitro are discussed. Gibberellins, jasmonates (JA) and abscisic acid (ABA) are the major identified plant growth regulators (PGRs) for storage organ form...

PURPOSE To develop a new corneal storage medium with a simple formula and evaluate it by histological methods. METHODS Two corneal storage media containing minimum essential medium and 2.5% chondroitin sulfate (pH 7.33), with osmolarity of 320 mOsm/kg, were compared to Optisol-GS. The differences in the two media were the molecular weight (MW) and the source of chondroitin sulfate. The MW of ...
