In Vitro Organogenesis in Rumex Thyrsiflorus Fingerh. – Problems of Sex Ratios
نویسندگان
چکیده
Rumex thyrsiflorus Fingerh. is one of the few dioecious plant species, which have sex chromosomes. We conducted the preliminary experiments to determine the type of morphogenesis of R. thyrsiflorus explants cultured in vitro and to verify, using PCR-based methods, if there is the relationship between sex and morphogenetic response of explants micropropagated under in vitro conditions. The results of our studies revealed the female-biased sex ratios among explants cultured in vitro (M:F=1:1.7). The female-biased sex ratios in case of explants showed organogenesis in vitro (M:F=1:2.44) may suggest a higher regeneration ability of female explants.

Growth and Survival Responses of Rumex Species to Flooded and Submerged Conditions: The Importance of Shoot Elongation, Underwater Photosynthesis and Reserve Carbohydrates
Plants of Rumex thyrsiflorus Fingerh., R. crispus L. and R. muritimus L., which are zoned along a gradient of elevation in a river foreland ecosystem, and differ in their flood-tolerance, were subjected to different Hooding levels. Under conditions of soil flooding, the growth rates of the flood-tolerant R. crispus and R. muritimus were as high as under drained conditions, but that of the flood...

Soil flooding results in unusually low oxygen concentra tions and high ethylene concentrations in the roots of plants. This gas composition had a strongly negative effect on root elongation of two Rumex species. The effect of low >xygen concentrations was less severe when roots conained aerenchymatous tissues, such as in R. palustris Sm. thyrsiflorus Fingerh., which has little root porosity, w...

The growth characteristics of three Rumex species were determined under different solution oxygen concentrations in hydroculture. These species all occur in a river foreland ecosystem and they were found to differ in their flood tolerance. The flood-tolerant R. maritimus and R. crispus developed a large num ber of new, aerenchymatous roots within a short period under low solution oxygen concent...
متن کاملAmmonium to Nitrate Ratio Affects Protocorm Like Bodies PLB Formation In vitro of Hybrid Cymbidium
Carbon and nitrogen are the two elements that most affect plant organogenesis. In vitro, usually as part of the macronutrients. Some anecdotal evidence from the literature suggests that the ammonium (NH4+) to nitrate (NO3–) ratio may affect orchid organogenesis. In this study, to test this hypothesis, different NH4+: NO3– ratios were tested on the development of protocorm-like bodies (PLBs) of ...
