Productivity of sunflower is strongly regulated by the availability of water. In order to study the influence of deficit irrigation (I1:100% FC, I2 and I3: 75 and 50% FC during stem elongation period,...
In recent years, the use of sunflower seeds sorted by seed size has been extensively increased in Turkey but little is known about the effects of seed size on germination, emergence, seedling gr...
In the tropics, crops sown in the late season are subjected to concurrent stresses of high air and soil temperatures, large saturation vapour pressure deficits and negligible soil water regimes. The r...
This research was carried out to determine the hybrid vigour (heterosis) for certain agronomical characteristics in the new - improved hybrid combinations in sunflower, during the years 1994 - 1995 a...
Some agronomical characteristics of newly improved synthetic sunflower varieties were investigated during the years 1994 and 1995 at Uludağ University, in the Faculty of Agriculture, Field-Crops ...
In eastern Anatolia, the sunflower (Helianthus annuus L.) has been grown as a confectionary crop for a long time, but oilseed sunflower types have more recently been grown commercially. No informatio...
Sunflower (Helianthus annuus L.) is one of the most important oil crops in the world due to its excellent oil quality. This research was conducted to evaluate changes in the contents of oil, fatty ac...
The experiments, involving 25 sunflower hybrids, were conducted in 3 locations in 2000 and 2001. These hybrids were evaluated for 4 important yield components (seed and oil yields, oil content and hul...
This study was designed to evaluate different threshold crop water stress index (CWSI) values to schedule irrigation for sunflower (Helianthus annuus L.) grown under furrow irrigation. Irrigations wer...
The relation between crop growing and soil tillage treatment are play important role in agricultural production. Soils under conventional tillage (CT) generally have lower bulk density and associated ...
【目的】建立向日葵不同外植体离体培养再生体系,为向日葵遗传转化、突变体筛选奠定基础。【方法】以不同基因型向日葵为材料,研究了向日葵不同外植体在不同的培养基中诱导不定芽再生的频率。【结果】向日葵不同基因型外植体在含适宜吲哚-3-乙酸(IAA)、6-苄氨基嘌呤(6-BA)等激素的培养基中均较易形成愈伤组织,但愈伤组织诱导不定芽的能力则较弱;不同基因型向日葵外植体的不定芽诱导率依次为子叶节>下胚轴>子叶...
With a view to establish the effect of some plant growth regulators on sunfl ower (Helianthus annuus L.) production and oil content was made an experiment. The investigation was made on Bulgarian sunf...
