- Abstract
This study was conducted in order to determine the nectar and pollen amount in phacelia (Phacelia tanacetifolia Bentham) and its flowering phenology under Çukurova region conditions. The planting of placelia plant in Çukurova conditions was conducted at November 25th, 1999. The first flowering period of phacelia started at April 4th, 2000, and it ended at May 22nd, 2000. It was determined the phacelia plant stayed in flower for 50 days under Çukurova region conditions. In order to determine the flower density in parcel where phacelia was planted, flower counting was performed for once in a week in 3 points with 0.30 m2 surface each during flowering period. As a result of those countings, it was found that the flower densities of phacelia plant were 176.33 pcs/m2 at the beginning of flowering, 6538.67 pcs/ m2 at the most dense period of flowering, and 508.33 pcs/m2 at decreasing period of flowering. It was found that there was a statistically significant relationship between measurement periods and the numbers of flowers (P<0.01) in phacelia plant. It was also determined that phacelia plant takes place within 4th class nectary plants with its 14.45 kg/h nectar potential by excreting averagely 0.66 mg/flower/day of nectar. Also it was found that the dry matter content of its nectar was 15.90%. It was revealed that phacelia plant excretes 0.56 mg/flower pollen daily, and it provides 12.26 kg/h productivity in terms of pollen productivity. It was expressed that the phacelia plant planted under Çukurova region conditions provides enough pollen and nectar source during its flowering period.
