| Summary: | The current paper has considered the effect of the development degree of the leaf conducting systems and the head-bearing internode on kernel weight per head of the winter wheat grown in the conditions of insufficient moisture supply and optimal moisture. The study of out among 13 winter wheat samples developed by the FSBSI “Agricultural Research Center “Donskoy”. The area of the conducting vascular bundle of winter wheat ranged from 0.208 mm2 10-4 (‘Shef’, ‘586/13’) to 0.364 mm2 10-4 (‘Krasa Dona’) (a trial) and from 0.381 mm2 10-4 (‘Etyud’) to 0.350 mm2 10-4 (‘Zhavoronok’) (a control). The maximum development degree of wheat leaf conducting system in the trials was identified in the varieties ‘Krasa Dona’ (4.01 mm2 10-4) and ‘Ambar’ (4.22 mm2 10-4), and in the control these were the varieties ‘Polina’ (2.59 mm2 10-4) and ‘Ambar’ (2.62 mm2 10-4). The maximum values of the area of the leaf conducting system and kernel weight per head were shown by the varieties ‘Krasa Dona’ (4.01 mm2 10-4 and 0.37 g) and ‘Ambar’ (4.22 mm2 10-4 and 0.39 g). |
