Relation Between Frost-Resistance of Winter Grains, Their Respiration Rate and Water – Soluble Carbohydrates Content in Autumn - Spring Period
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2013, Vol 9, Issue 4
Abstract
The content of water-soluble carbohydrates and respiration rate in the crown tissue of winter wheat, rye and triticale in autumn – winter – spring were studied. In the period and of winter significant differences were revealed between winter crops in the rate of respiration and content of carbohydrates. Respiration of wheat in mid-March increased over February to 33%, and the content of carbohydrates during this period decreased by 10%. Despite the increase in environment temperature by mid-March of winter rye and triticale showed not increase, but rather decrease in the rate of respiration. A higher level of plant resistance of winter rye and triticale to low temperatures, as compared to winter wheat is associated with carbohydrate status and higher stability of respiration process in winter rye and triticale in response to temperature rise in end of winter.
