Оцінка генеративної сфери catalpa bignonioides та c. Speciosa в умовах придорожньої лісосмуги
Generative sphere states of Catalpa bignonioides and C. specious under condition of the roadside forest belt

Summary/Abstract: Research of the generative sphere of plant genus Catalpa in the roadside forest belt was conducted. The belt’s ecological condition leads to the depression of blossoming and fruiting of C. bignonioides Walt. and C. speciosa Ward. The qualitative and quantitative characteristics of fruits and seeds were changed in comparison with a control. The changes in fruiting parameters are greater than flowering. Flowering characteristics of both species changed almost identically, with the exception of the blossom cluster length. The description of fruiting changed substantially in C. speciosa Ward.
