Investigation of vegetative properties and generative production of the potential ornamental and narrow endemic species Verbascum yurtkuranianum (Scrophulariaceae) for ex situ conservation

Verbascum yurtkuranianum is a narrow endemic species occurring in single location, the northern Bursa province (Turkey). It an endangered and potentially ornamental plant. No conducted study on its life biology, production, aesthetic features available. This aimed to reveal vegetative properties, seed characteristics, methods requirements for germination, germination speed, potential value so it can be conserved ex situ produced. has as plant regarding flower. revealed that total number of individuals 788. Without any treatment, 70.7% rate achieved if seeds are stored at 4 °C. The optimum temperature was from 15 20 °C (77.3% 78.7%, respectively), photoperiod regulation 12/12 or 8/16 (light/dark) hours (74.7% 76.0%, respectively). most effective treatment promote found by implementation 60 min ultrasonic waves (94.3%) application 120 vacuum (95.3%).
