The genus Delphinium belongs to the Delphinieae tribe and Ranunculaceae family; in Iran according to flora Iranica has 29 species with zygomorphic flower. In this study, the morphological information of flower and spur in Delphinium species was studied to determine the importance of these characters in identifying species of this genus. Inflorescence condition, flower color, sepal flower, the color of sepals and petals comparative to each other, spur shape, spur curvature and spur tip were investigated. Statical analysis was conducted by SPSS software and cluster analysis was performed by Average linkage method. The results showed that flower color is one of the important traits in identifying Iranian Delphinium species, so that these genera are divided into two groups of yellow and non-yellow flower. Also, shape and spur curvature can differ from cylindrical, attenuate and inflatum. However, these character don’t correlate with distribution and the area where plant is grown. D. saniculifolium has a inflatum spur among specimens. Herbarium image of flower in different species are presented.

In order to investigate the effect of removing inflorescence and seed tuber size on yield and yield components of potato, the experiment was conducted using a factorial method based on randomized complete block design with three replications in a farm located in evoghlu region of Khoy city, during spring of 2014. The first factor was removal of inflorescence at two levels including removal and non-removal of inflorescence and the second factor was the seed tuber size at six levels including 25-35 g, 35-45 g, 45-55 g, 55-65 g, 65-75 g, and 75-85 g. The results indicated that the effect of removing inflorescence and seed tuber size was significant on tuber size, weight of tuber in plant, the number of branches and leaves in plant, leaf area index and tuber yield. So that the highest leaf area index (5.48) obtained from the treatment of inflorescence removing and tuber yield also in the treatment of inflorescence removing increased by 2.68 tons per hectare (%15). In regard with seed tuber size, the highest rates of tuber yield were 22.64 and 21.89 tons per hectare which were respectively obtained for seed tuber sizes of 65-75 g and 75-85 g. There was no significant difference between these two sizes of seed tuber in regard with tuber yield. Therefore, inflorescence removing is effective in yield increasing due to elimination of un useful sink, also seed tuber size of 65-75 g is recommended in order to save seed consumption and reduce costs.

To study the response of some morphological traits, yield and essence of fennel, to foliar application of salicylic acid and phosphate 2 bio-fertilizers, an experiment was conducted in Research Farm of Islamic Azad University Branch of Malekan in 2013. The experimental was conducted as randomized complete blocks with three replications. The factors was included foliar application of salicylic acid at three concentrations (non-foliar and foliar application of 30 and 60 mmol/lit), and fertile phosphate 2 (non-inoculation and inoculation). Results showed that foliar application of salicylic acid with biofertilizer had significant effects on traits including plant height, shoot dry matter, grains per plant, thousand grain weight, grain yield, harvest index and yield essential oil. The highest grains per plant (2274), plant height (63.6 cm), percentage of essential oil (3.24%) and yield essential oil (0.96 g/plant) were obtained with application of 60 mmol/lit salicylic acid. Also the highest grain yield (3215.6 kg/ha), grains per plant (2215), plant height (63.18 cm) and yield essential oil (0.85 g/plant) were achieved with application of fertile phosphate 2. It seems that application of salicylic acid and fertile phosphate 2 bio-fertilizers due to the improvement of some traits such as grain yield, essence and grains per plant can be recommended for profitable fennel production.
