Abstract
The puropose of this study is determination of optimize conditions in root culture of Carthamus tinctorius L. to obtain more amounts of roots that may have remarkable ability in production of important compounds with different uses. As Carthamus tinctorius L. is a plant with known benefits in industrial, edible and medicinal fields, optimization of their root culture condition is desired. In the present work, one of the condition that is considered for this purpose is light condition. Light condition included darkness and lighting. The next factor has been studied here was pH factor. In this method roots derived from young stems of the growth seeds in solid MS medium were transferred to liquid MS medium and after regeneration and more growth were exposed to mentioned treatments. After 21 days was measured fresh and dry weight, special pigment of Carthamus tinctorious L .(red pigment concentration at 517 nm and yellow pigment concentration at 403,321nm), photosynthetic pigments (Chla, Chlb, Total chlorophyll, Carotenoid) in samples. The most important achievement of researches obtain to remarkable amounts of special pigment of Carthamus tinctorious L. and photosynthetic pigments in root of plant that later reported in shoot parts and flowers. Addition observations and results indicate light condition has great impact on growth mean and produce compound rather than dark condition and in case of second treatment(pH factor) Carthamus tinctorious L. has been adopted with whole used pH range to increase growth and compounds production.
