In this work habitats impact to dandelion´s anatomic and morphologic state.
Dandelion´s leaf is dorsoventral, bifaciral type. Mesophyll habitat epidermal cells are izodeometric, waved, whereas in the higrophyll – slightly waved and extended in tangential direction. Mesophyll habitat epidermal cells´ number is bigger than in the higrophyll. In the mesophyll habitat on the upper epidermal cells´ number is 85,4, on the lower – 87,2 per 1 mm², accordingly in the higrophyll habitat – 79,3 and 82,4 per 1 mm². Stomata apparatus per 1mm² are more in the higrophyll habitat (on the upper lamina´s side there were 20,2, on the lower – 24,9 stomata apparatus), than in the mesophyll (on the upper lamina´s side there were 14,8, on the lowe – 19,5 stomata apparatus). In the mesophyll habitat upper lamina´s side stomata´s coefficient was 19,36% and 45,57%.
Dandelion´s leafstalk is ivugularly – shaped trapezium. In the mesophyll habitat – double, in the higrophyll – single, air spaces´ diameter – 1056 ��. In the lamina´s epidermis the stomata apparatus is not found neither on the upper, nor on the lower side. Dandelion´s leafstalk is represented by tabular collenchyma. In the leafstalk´s parenchyma articulate communicating latex vessel are situated.
Investigated on the Taraxacum officinale, wich is growing in the mesophyll and higrophyll habitats, anatomic state of radix is definited that changing habitat the anatomic state of radix shifts a little bit. Independent of habitat radix is... [to full text]
