In this study, the planting biology of the countryside (Convolvulus arvensis), which is a problem in agricultural fields, and the pink-flower evening seafood (Ipomoea triloba) was studied. Sulphuric acid (15, 30, 45, 60, 90 and 120 minutes) to break the stumbling in the seeds.Sodium hydroxide (5, 10, 20, 30 and 40 min.The effects of the application of gingeric acid (250, 500, 750, 1000 and 2000 ppm), microwave (10, 30, 60, 90, 120 and 150 s), hot water (10, 15, 30, 60 and 120 s), mechanical infusion and hot+cold water (5, 10 and 15 times) have been studied. According to the results obtained; 90 and 120 minutes for C. arvensis.H2SO4 for triloba I, 15, 30, 45, 60, 90 and 120 minutes.The H2SO4 application has been identified as the best dormansi break-up applications. The minimum, optimal and maximum grinding temperatures of the seeds are determined as 10 oC, 20-30 oC and 40 oC for C. arvensis, respectively; 15 oC, 25-30 oC and 40 oC for I. triloba.

Germination biology of field bindweed (Convolvulus arvensis) and three-lobe morningglory (Ipomoea triloba) was investigated in this study. The effects of sulfuric acid (15, 30, 45, 60, 90 and 120 min), sodium hydroxide (5, 10, 20, 30 and 40 min), gibberellic acid (250, 500, 750, 1000 and 2000 ppm), microwave (10, 30, 60, 90, 120 and 150 s), hot water (10, 15, 30, 60 and 120 s), mechanical scarification and hot+cold water (5, 10 and 15 times) applications were investigated in order to break the dormancy of the seeds. According to the results, breaking dormancy studies in the applications examined C. arvensis for 90 and 120 min H2SO4; for I. triloba 15, 30, 45, 60, 90 and 120 min H2SO4 applications were found to be the best breaking dormancy application. Minimum, optimum and maximum temperatures were determined as 10, 20-30 and 40 ºC for C. arvensis; 15, 25-30 and 40 ºC for I. triloba.
