Abstract
This study was carried out to investigate the relationship between in vitro competition and stress, and their effects on seedling growth of three flax (Linum usitatissimum) cultivars ( Madaras , Clarck , and 1886 Sel. ). Competition among plants was achieved by changing the distances they sown. Four different distances were used as 0.5x0.5 , 1.0x1.0 , 1.5x1.5 and 2.0x2.0 cm. The results showed that encouraging seedlings for competition by decreasing the distances among seeds sown per Magenta vessel elevated chlorophyll contents (chl. a, b and total chl.), seedling height and root length significantly up to a threshold from where stress initiated and significant decreases in all parameters were observed. In term of chlorophyll contents (chl. a, b and total chl.), seedling height and root length, the highest results (1540.1, 581.9, and 1253.7 μg/g tissue, 4.54 and 7.77 cm, respectively) were obtained from 1.5x1.5 cm distance in cv. Madaras . For cv. Clarck , the highest values in chlorophyll contents (chl. a, b and total chl.), seedling height and root length were recorded as 1860.6, 652.6, and 1429.0 μg/g tissue, 4.58 and 6.79 cm, respectively in 1.5x1.5 cm distance application. The highest results with respect to chlorophyll contents (chl. a, b and total chl.), seedling height and root length were aigain recorded at 1.5x1.5 cm distance application in cv. 1886 Sel. as 1782.6, 552.0, and 1138.7 μg/g tissue, 4.62 and 6.45 cm, respectively. As a consequence, the application of 1.5x1.5 cm distance seems to best for all cultivars. This study showed that competition among in vitro-grown seedlings which can be the source of explants may be used to increase the success of tissue culture studies.
