In Europe on the whole as well as in Yugoslavia, the most widespread weed species from the genus Solanum is Solanum nigrum L. Since this species inhabits different habitats, it developed several ways of adaptation to environmental conditions. The influence of ecological factors on plant organism and resulting plant adaptations are most evident in leaf morphology and anatomy. Therefore, the anatomical structure of leaves and leaf epidermal tissue of S. nigrum was analyzed and compared among plants that originated from different habitats, in order to determine leaf structural adaptations. S. nigrum lamina has the mesomorphic structure with some xero-heliomorphic adaptations. The differences in stomata number, number of hairs, thickness of lamina, palisade and spongy tissue, as well as the size of mesophyll cells have been noticed. The highest values for most of the parameters have been recorded for the plants from cultivated soil. Largest variations of the examined characters were found for the leaves from ruderal habitats, where environmental conditions are most variable.

Sweetpotato (Ipomoea batatas (L) Lam) plants are highly susceptible to weed competition during their early field establishment period For a long time the contact herbicide paraquat has been widely used within the sweetpotato production system often as the only herbicide applied to control weeds that emerge within the crop A low rate of paraquat is applied repeatedly over the crop each season eliminating seedling weeds at a very young stage until the crop canopy provides adequate competition However the application of paraquat to selectively destroy seedling weeds has inadvertently selected for paraquatresistant weed biotypes This study confirms growers field observations that populations of paraquatresistant solanaceous weeds are now common identifying them as Solanum nigrum L and S americanum Mill Paraquat cannot be used selectively when these resistant biotypes are present as the concentrations required to control the weed species would be lethal to the crop itself

Aim. Studying of black nightshade young plants’ response to the induced mechanical stresses. Methods. Researches conducted in small plot fi eld experiments. Results. Change of sensitivity level of Solanum nigrum L. plants depending on phases of their development at the moment of damage of elevated parts has been proven. Owing to loss of the surface capable to photosynthesis, there is an essential decrease in volumes of photosynthesis at plants of weed survived and their possibilities of ontogeny passage. The deep induced dis- stresses reduce biological effi ciency of plants, their ability to accumulate weight and to form seeds and even lead them to death. Conclusions. The defi ned principles of response of weed plants to the induced mechanical dis-stresses are can be used for working out and ecological receptions of crops protection from weeds.

Leaf Anatomical Characteristics

The effect of water stress on gas exchange, water relations and leaf anatomical characteristics have been studied in two olive cultivars (Olea europea, L. cv. ‘Koroneiki’ and cv. ‚Mastoidis’). Photosynthetic rate as well as stomatal conductance were decreased in stressed plants. Osmotic potential (π) declined rapidly in stressed plants indicating their ability for osmoregulation. Bulk modulus of elasticity (ε) was significantly higher in stressed compared to well irrigated plants. The volume fraction of intercellular spaces of the upper palisade parenchyma, the spongy parenchyma as well as the lower palisade parenchyma were significantly lower in stressed compared to well irrigated plants. On the other hand, the density of mesophyll cells in the upper palisade parenchyma, spongy parenchyma and lower palisade parenchyma increased significantly in stressed plants
