One of the most popular and usable Aromatic plants are kinds of Basilica (Ocimum sp., Lamiaceae). This genius has different characteristics in behavior germination. Biodynamic agriculture is a new science in the research and especially the position of stars and planet relative to each other, position of moon around the earth and seasonal change and Solar and lunar eclipses. We must demonstrate this theory. In this experiment, we want to record the effect of based on two calendars (biodynamic and Astronomic) on three ecotypes of Basilica seed germination. The base of this experiment was a randomized block design with three replications. We used 50 seeds in Falcon tube (value=15ml) and recorded the weight and value of seeds in tube. Then we added 5ml of water in tube and shacked after moisturized and control and recorded the Mucilage value and another behavior of seed germination in lab condition. Results showed that different position of some planets such as moon and Mars and Jupiter had the highest effect, positive and significant effect on mucilage percent (p>95%), germination speed and length of root. Therefore, we could express the lunar position had the highest effect on root length of local type and the lowest effect on purple basil. Mucilage percentage of seed coat in green basil had the highest content relative to another ecotype and this content was significant (p>95%). Thus, the best suggestion for the produce of mucilage from the basil seeds, the best time is the first quadrature of the moon.

Cistus is one of the most characteristic genera of the Mediterranean flora. These species, natives of lands surrounding the Mediterranean Sea, are present in scrubland and garigue on siliceous ground and often on acid soil; seven species in particular are founded in Sicily. The adaptation of the genus to Mediterranean environments is evident from ecological characteristics such as fire-dependent seed germination; the heat generated by fire is in fact a key germination input.In this view, two experiments were performed to study the effects of high temperature on germination of four Cistus species (C. creticus L., C. crispus L., C. monspeliensis L., C. salviifolius L.). In the first, in relation to untreated control, 7 different high temperature pre-treatments (from 70°C to 130°C) for different timings (from 1 to 10 minutes) were analysed in relation to two sowing strategies (soon after the seed collection and after a 6 month period at 5°C to simulate the winter season effects). The pre-treatment with high temperatures can improve the germination; the storage at 5°C to simulate the winter season effects did not modify the germination process. In any case the results showed a species-dependent response. High germination percentage was obtained for C. creticus, while a lower germination rate was achieved by C. crispus and C. monspeliensis.In the second experiment, seeds were treated for different periods (80°C for 10 min, 90°C for 5 min and 100°C for 1 min) with high temperature in dry and wet (immersion in distilled water) conditions. Also in this case the responses were strictly linked to the species. Especially C. crispus and C. monspeliensis showed high germination percentage in wet conditions. In all species the wet heat treatments determined an accelerating of process like demonstrated by lower T50 values.
