Growth dynamics of endemic Dracaena cinnabari
Dragon ́s blood tree, a flagship endemic species of Socotra, is threatened with extinction 23 due to lack of natural regeneration, likely because of goat herbivory and/or climatic factors. Loss of 24 dragon ́s blood tree would result in loss of other native flora, heightening the importance of 25 formulating a conservation strategy for it. Although artificial afforestation might be used to offset...
متن کاملGermination under Saline Conditions’
Three mutant strains of Arabidopsis thaliana var Columbia were selected for their ability to germinate in elevated concentrations of NaCI. They were not more tolerant than wild type at subsequent development stages. Wild-type strains could not germinate at concentrations >125 mM NaCI. l w o of the mutant strains, RS17 and RS20, could withstand up to 225 mM, whereas RS19 was resistant to 175 mM....
متن کاملTemperature regulation of germination in crimson clover seeds.
Seeds of Dixie crimson clover (Trifolium incarnatum cv. Dixie) completed germination in 36 hours at 20 C. At 10 C germination was delayed by 24 hours. At 30 C only 20% germinated and the rest remained viable for a long time but not germinable. Different patterns of adenylate energy state and zymograms of acid phosphatase and esterase were observed from seeds grown under the three temperatures f...
متن کاملSeeds use temperature cues to ensure germination under nurse-plant shade in xeric Kalahari savannah.
BACKGROUND AND AIMS In arid environments many plant species are found associated with the canopies of woody perennials. Favourable conditions for establishment under canopies are likely to be associated with shade, but under canopies shade is distributed patchily and differs in quality. Diurnal temperature fluctuations and maximum temperatures could be reliable indicators of safe sites. Here, a...
متن کاملAcute and sub-acute oral toxicity of Dracaena cinnabari resin methanol extract in rats
BACKGROUND Dracaena cinnabari (DC) is a perennial tree that located on the Southern coast of Yemen native to the Socotra Island. This tree produces a deep red resin known as the Dragon's blood, the Twobrother's Blood or Damm Alakhwain. The current study performed to evaluate the safety of the DC resin methanol extract after a single or 28 consecutive daily oral administrations. METHODS In ass...
