Effect of Cold Temperature and Duration on Carbohydrate Spectrum Changes in Three Genotypes of Lilium ledebourii’s Bulb
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 8
Abstract
Present study was conducted in order to understand sugar mobilization and effect of vernalization temperatures and duration in Lilium ledebourii’s bulb. Three genotypes were collected from Rudbar, Kelardasht and Ardebil regions. The period of vernalization was 5 and 10 weeks, and vernalization temperature was 3 and 9 °C. Bulb’s total sugar, Starch, glucose, fructose and sucrose were measured in first, second, fourth, eighth and tenth week of vernalization. Data were analyzed with SAS software in completely randomized design. Results showed that starch and total sugar reduced gradually, exception an increasing peak in 5th weeks in total sugar content. Sucrose and fructose content reduced, but glucose had constant value during vernalization. Starch and total sugar in 9 °C were significantly more than 3 °C vernalization temperature. Rudbar had significantly more fructose and total sugar content between three genotypes.
