The protocol described in this paper provides optimal levels of growth regulators required to obtain high regeneration rates of Cistus in vitro. Micropropagation has been achieved through rapid proliferation of shoot-tips on Murashige and Skoog (MS) basal medium supplemented with 0.2 mg l -1 6-benzylaminopurine (BAP). After four weeks shoots were transferred to MS medium without growth regulators for further development and rooting. The highest percentage of regenerated shoots was obtained with 0.1 mg l -1 TDZ and 0.1 mg l -1 NAA after 4 weeks. Elongation and rooting was readily achieved when multiple shoots more than 1 cm in length were singled out and cultured on the MS medium without growth regulators. The plantlets were successfully adapted and grew vigorously in greenhouse conditions. This is the first report of shoot regeneration in the genus Cistus. The regeneration protocol developed in this study provides a basis for further investigation of the medicinally active constituents of this elite medicinal plant.

The flattened roofs and the extra space given to the appartment was used for amenity. In the 1970’s, people started appreciating the value of alternating the cityscape with the coverage of large parking spaces and the roof terraces were transformed into green roofs. However, it was not until the 1980’s that the environmental aspects of such structures started coming into consideration as people sought environmental solutions for the increasingly ongested cities. In contemporary times the bioclimatic and the economic advantages that the green roofs provide to buildings have become an integral part of their design. Roof terraces are not positioned any more on the top of a structure, they are the structure and together with other structural matters function as a living organism allowing the control of the environmental at...

The flattened roofs and the extra space given to the appartment was used for amenity. In the 1970's, people started appreciating the value of alternating the cityscape with the coverage of large parking spaces and the roof terraces were transformed into green roofs. However, it was not until the 1980's that the environmental aspects of such structures started coming into consideration as people sought environmental solutions for the increasingly congested cities. In contemporary times the bioclimatic and the economic advantages that the green roofs provide to buildings have become an integral part of their design. Roof terraces are not positioned any more on the top of a structure, they are the structure and together with other structural matters function as a living organism allowing the control of the environmental attributes inside and outside the building. The new trends emphasize the importance of vegetation in the architectural design to regulate the energy consumption and the thermical comfort of the building while, at the same time, rendering that soft texture to the appearance of the structure that only natural elements could provide. Landscape architecture as the only practice that can combine architectural design with vegetation has a primary role in the transformation of the urban space. New possibilities are emerging where landscape architects can exploit the bond between architecture and landscape elements in order to rearrange the urban texture and create a more livable cityspace.
