Action of Phytochrome During Prechilling of Amaranthus retroflexus L. Seeds.
Dark germination of Amaranthus retroflexus L. seeds at 35 degrees increased after several days of prechilling at 20 degrees or lower. Irradiation with far-red light for short periods during the early hours of a prechilling period at 10 degrees inhibited subsequent dark germination at 35 degrees . The inhibition was completely reversible with red light. Far-red irradiation in the latter part of ...
متن کاملRehydration of Phytochrome in Imbibing Seeds of Amaranthus retroflexus L.
It is commonly recognized that light-sensitive seeds require a period of imbibition before full promotion of germination by a light stimulus can be attained. Yet little work describes the nature of these preliminary events. Of the several major limitations that may be involved, clearly the rehydration (or activation) of phytochrome and the system with which it interacts are the chief ones to co...
متن کاملAllelopathic effects of Chenopodium album, Amaranthus retroflexus and Cynodon dactylon on germination and growth of safflower
According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...
متن کاملChanges in Phytochrome Expressed by Germination of Amaranthus retroflexus L. Seeds.
Effects of red (600 to 680 nanometers) and far red (700 to 760 nanometers) irradiances on Amaranthus retroflexus L. seeds indicate that synthesis of phytochrome in the red-absorbing form takes place in water-imbibed nongerminating seeds at 35 C. After 96 hours in darkness, conversion of about 0.10% phytochrome to the far red-absorbing form induces 50% germination. Continuous far red radiation a...
متن کاملAllelopathic Effects of Sisymbrium irio L. and Descurainia sophia (L.) Schur on the Germination of Wheat (Triticum aestivum L.)
An experiment was conducted under controlled conditions to study the effect of water extract of leaves, shoots and roots of either Sisymbrium irio L. =SISIR and/or Descurainia sophia (L.) Schur =DESSO on the germination and primary growth of wheat. A split-split plot experiment in CRD with three replications was used. The main plots were the type of weed: i.e. SISIR and DESSO and the sub-plots ...
