Due to botanical tulips' economic interest coupled with limited information regarding their seed germination, we investigated the effect of temperature on dormancy release and germination in two endangered local endemic tulip species of Greece ( Heldr., Heldr.).

The aim of the present study was to investigate the effect of temperature on seed germination of the local, wild-growing Greek endemics and and the sub-Balkan endemic , which are threatened with extinction, as well as the Mediterranean and the Asiatic naturalized on Chios Island (Greece). The germination responses at five constant temperatures (5, 10, 15, 20, and 25 °C) were assessed for all studied species in growth chambers under a 12:12 light-dark photoperiod.

For ecologists, the core of the issue is whether or not two species' distribution taken from the same habitat are the same or distinct. The Shannon index and Simpson diversity are well-known in ecology; however, the non-linearity of these indices may cause a misinterpretation of the underlying diversity, as shown by Lou Jost (2006) and others.

We sourced multifaceted evaluations for three economic sectors performed in three levels, using 48 attributes and eight criteria from previous studies of our own, and the relevant species-specific assessments are overviewed herein in detail.

Background: is a valuable Mediterranean shrub as an ornamental plant as well as fruit tree. Fresh fruits of are a good source of antioxidants, of vitamins C, E and carotenoids and also are characterized by the high content of mineral elements.
Materials And Methods: The effects of gibberellic acid (GA) and cold stratification (CS) on seed germination performance were investigated in seeds collected from three provenances in the Northern part of Greece.
