چکیده

15 The geodiversity of Crete is quantified in this study, based on the classification of 16 geomorphometric, geological and climatic factors. A number of geomorphometric variables, 17 extracted from the ASTER Global Digital Elevation Model (ASTER G-DEM) in conjunction 18 with geological and climatic information, are evaluated through various algorithms incorporated 19 into Geographical Information System (GIS) software’s. The derived geoinformatic data sets are 20 2 then analyzed to produce the geodiversity of Crete. The geodiversity map is used to quantify the 21 geodiversity, by calculating landscape diversity and other spatial pattern indices. Those indices 22 are evaluating the richness, evenness, fragmentation and shape of the landscape patch types. The 23 outcome of this study has highlighted that western Crete is characterized by complex 24 geodiversity with more irregular, elongated and fragmented landscape patterns relative to the 25 eastern part of the island. The geodiversity indices provide insights into the processes shaping 26 landscapes, particularly the "battle" between neotectonic landscape deformation and 27 erosion/deposition. The methodology presented can be useful for decision makers when 28 evaluating a regions geological heritage, planning the management of natural resources, or 29 designating areas for conservation. 30

Effect of Methyl Jasmonate and Sucrose on Endogenous Non-structural Carbohydrates in Petals and Leaves of Cut ‘First Red’ Roses (Rosa hybrida L.)

Effects of exogenously applied methyl jasmonate (MeJA) and sucrose on vase life and non-structural carbohydrate concentration in petals and leaves of cut ‘First Red’ roses were investigated. Roses were placed in sealed plastic containers and received MeJA vapour treatment (0.1 μL MeJA L-1) for 24 h at 20°C. Flowers were then placed in individual bottles containing 0 or 2% (v/v) sucrose solution...
