    Effects of different planting depth and bulb sizes on yield and yield components of saffron (Crocus sativus L.)
    (Ankara University, 2009) Ipek, Arif; Arslan, Neşet; Sarihan, Ercüment O.
    Saffron (Crocus sativus L.) is known as one of the earliest cultivated plants. Formerly having importance as spice, dye and medicinal plant and cultivated in Bolu, Tokat, Şanliurfa, Adana, Izmir provinces, saffron plantation areas have decreased gradually and it is cultivated by some farmers in Safranbolu district Turkey only. The foremost barrier is limitation in bulb (corms) production to develop cultivation of this plant. This study was carried out in the experimental field of the University of Ankara, Faculty of Agriculture, Department of Field Crops. The aim of the study was to evaluate the effect of planting depth and bulb size on production of the bulbs and different sized saffron bulbs were planted in rows 10 cm apart with inter row spacing of 20 cm of planting depths were 5,10 and 15 cm in 2002 and harvested in 2004. Both planting depth and bulb size affected both flowering and developing of daughter bulbs.

    Relationship between seed age and germination rate in great burdock (Arctium lappa)
    (2005) ?pek, Ar?f; Sarihan, Ercüment O.; Gürbüz, B?lal
    The germination tests were carried out at the seed testing laboratory of Field Crops Department, Faculty of Agricultural, University of Ankara, in 2003. The seeds were treated with GA3 (0, 100, 200 and 400 ppm) and KNO3 (0, 0.1, 0.2 and 0.4 %). The highest germination rate (88%) was obtained in the seeds treated with GA3 (100 ppm) belonging to the year 2001. However, no germination was recorded in 10 years old seeds. Germination rate in the control seeds decreased regularly from 78% to 0%. The GA3 and KNO3 had positive effect on germination of older seeds.
