Abstract

This study aimed to investigate the ornamental utilization, two-year growth performance in natural habitat and cultural conditions, generative production methods, and morphologic and phenologic plant properties of Campanula grandis, which is an endemic species demonstrating ornamental plant potential and needs ex-situ conservation and cultivation. In addition, the germination and growth performance of seeds collected in the new season was compared with seeds that were kept for one year. Seeds stored dry for 3 months at 4 °C and then treated with 200 ppm GA3 exhibited the highest germination percentage (76%). Furthermore, GA3 treated seeds had best germination speed, shortening the germination time. This study also identified the ideal temperature for germination as 20 °C for the best germination rate. It was revealed that the number of flowers on the plant in natural habitat was 48 while in cultural conditions it was found as 165 flowers in biennial plants. The seedlings were planted in an ex-situ collection garden established for placing the Campanula grandis species under conservation. The Campanula grandis species has the potential for use as an ornamental plant for landscaping applications due to its lengthy flowering period, vigorous second-year stem growth, and numerous, enormous, flamboyant, blue-purple, and bell-shaped flowers.
大风铃鱼的最佳发芽方法、观赏植物特征及迁地保护
本研究旨在研究桔梗的观赏利用、在自然栖息地和培养条件下的两年生长性能、繁殖生产方法以及形态和酚性植物特性。桔梗是一种具有观赏植物潜力的特有物种,需要迁地保护和栽培。此外,将新季节采集的种子与保存一年的种子的发芽和生长性能进行了比较。在4°C下干燥储存3个月,然后用200ppm GA3处理的种子表现出最高的发芽率(76%)。此外,GA3处理的种子发芽速度最好,缩短了发芽时间。本研究还确定了发芽的理想温度为20°C,以获得最佳发芽率。结果表明,在自然栖息地,该植物上的花朵数量为48朵,而在培养条件下,二年生植物上的花数为165朵。这些幼苗被种植在一个为保护桔梗物种而建立的迁地收集花园中。大风铃属植物由于其花期长、第二年茎生长旺盛、花朵众多、巨大、艳丽、蓝紫色和钟形,有潜力用作景观美化应用的观赏植物。
