Strength and quality of safflower seed (Sina cultivar) in the development and maturation of seeds, under irrigated and rain–fed planting, were evaluated in greenhouse of Faculty of Agriculture University of Mohaghegh Ardabili in 2010. The obtained seeds for this experiment were farming in Agricultural Research Station of Islamic Azad University – Ardabil Branch, Ardabil, Iran, treatments affected plant density and dry and irrigated cultivation conditions. experiment was conducted A factorial in randomized complete block design in 4 replications. Factors including planting method (irrigated and rainfed) and planting density (30, 40, 50 and 60 plants \m2). Seeds were sampled at intervals of 18 to 62 days after flowering and were determined the amount of moisture and dry weight and were planted in pots to measure the strength and quality of seeds. Traits measured in this experiment include: changes in seed dry weight, seed moisture content, root length, the cotyledons length, length of normal seedling, shoot fresh weight, percentage of normal seedlings, the percentage of emergence and rate of emergence. Results showed that weight handle end or grain filling period has occurred of 42 days after flowering or 137 days after implantation. Maximum hypocotyl length and root length were observed on dry conditions at 62 days after flowering. The highest emergence rate were obtained at 45–55 days after flowering that almost simultaneously with the processing power and weight that reflects the high quality seeds were produced in this process. For other quality traits such as percentage of normal seedlings, seedling length and percentage of normal emergenc, The highest strength and quality of seeds has been made in dry conditions and at the end of the sampling, 7 to 9 days after the weighting maturity<\div>

In order to study the effects of different plant densities on some morphological traits and the yield of safflower under irrigated and rain–fed planting conditions, an experiment was conducted in Agricultural Research Station of Islamic Azad University – Ardabil Branch, Ardabil, Iran in 2010. The experiment was factorial based on a Randomized Complete Block Design with four replications. The factors was included planting method (irrigated and rain–fed) and plant density (30, 40, 50 and 60 plants \m2). The measured traits was included the plant height, main stem basal diameter, height of the first head–bearing branch from ground, seed length, the number of main branch per m2, the number of secondary branch, head number per m2, and seed yield. The results showed that the diameter and height of plants were higher under irrigated conditions than under rain–fed conditions. The highest height of the first head–bearing branch from ground and main branch number were observed at the density of 60 plants per m2 under irrigated conditions. The plants at the density of 30 plants per m2 under irrigated conditions had higher secondary branch number and main stem diameter. Also, the highest head number per unit area was obtained from the plants at the densities of 40 and 60 plants per m2 under irrigated conditions. The significantly highest seed length was obtained at the density of 40 plants per m2 under rain–fed conditions. The significantly highest seed yield was produced at the density of 60 plants per m2 under irrigated conditions<\div>

The present study was carried out in research station of Islamic Azad University of Ardabil, Iran in 2010 as a factorial experiment based on a Randomized Complete Block Design with four replications. The studied factors included planting conditions (irrigated and rain–fed) and plant density (30, 40, 50 and 60 plants m–2) with the spacing of 8, 6, 5 and 4 cm, respectively. The seeds were sampled 18–62 days after flowering (DAF) and their moisture content and dry weight was measured. The studied traits included the variations of seed dry weight, root length, hypocotyl length, normal shoot length, normal shoot percentage, germination percentage, viable seeds percentage, electrical conductivity (EC) and germination rate. It was found that weight maturity or the end of grains filling period occurred 42 DAF or 137 days after sowing (DAS). The highest seed vigor for normal shoot percentage was obtained at the densities of 40 and 50 plants m–2 under irrigated conditions and at the density of 50 plants m–2 under rain–fed conditions. The highest germination percentage was related to the density of 50 plants m–2 before and\or concurrent with weight maturity. The highest germination rate was obtained at the high–est studied density (60 plants m–2) a few days before weight maturity. The highest seed quality for viable seeds percentage was obtained at the density of 40 plants m–2 under irrigated farming and at the density of 50 plants m–2 under rain–fed farming. However, the highest seed vigor and quality at different development and maturity stages in terms of EC was related to the lowest density (30 plants m–2) under irrigated farming and to the density of 50 plants m–2 8 days before weight maturity under rain–fed farming.<\div>
