Abstract
To evaluate the effect of methanol spraying under low irrigation conditions on quantitative and qualitative charactrieats of safflower, an experiment was conducted at the Agricultural Research Station, Sistan Earm, in 2012-2013 using a split plot arrangement in a randomized complete block design with three replication. Different irrigation schedules include: full irrigation, irrigation cut-off time in heading-bud and grain filling stages were considered as main factors and different levels of methanol include: control (no consumption of methanol), 7, 21, 35 and 49% by volume (v/v) were subsidiary factor. the results showed that, the low irrigation had a significant increase effect on proline, seed carbohydrate and protein, and had significant decrease impact on plant height, number brunch and auxiliary branches, number of leaf, leaf area index, leaf chlorophyll, fluorescence, number of heads, 1000 grain weight, seed and biological yield, harvest index and oil percentage. The highest and lowest seed yield was related to full irrigation and irrigation cut-off time in grain filling stage respectively and the former had 12.78 percentage increase in seed yield. Methanol spraying significantly increased plant height, branch number and auxiliary branches, number of leaf, leaf area index, leaf chlorophyll and fluorescence, number of heads, 1000 grain weight, seed and biological yield, harvest index, seed protein, seed carbohydrate and oil percentage, but proline was decreased. The maximum and minimum seed yield was related to spraying 21 percentage and 49 percentage methanol respectively, so that the former led to 12.38% increase in seed yield. Interaction of low irrigation and methanol spraying had a significant effect on branch number and auxiliary branches, chlorophyll, number of leaf, 1000 grain weight, seed yield, seed protein and soluble carbohydrates in seeds. Mean comparison of interactions showed that the highest seed yield was associated to spraying 21 percentage methanol that this treatment had about 29.20 percentage increase in yield Compared to spraying 49 percentage methanol with irrigation cutoff time in grain filling stage. Based on the results, spraying of 21 percentage methanol with full irrigation for safflower production can be proper treatment for the area.
