Bletilla striata: a review of seedling propagation and cultivation modes

Abstract

In recent years, the domestic and international market demand for Bletilla striata has increased rapidly because of its wide use in medical, pharmaceutical, chemical, health, cosmetology, and other fields. The increased demand and a shortage of wild herbal resources have led to the development of large-scale introduction and cultivation programs. Using our research results and the relevant literature, this paper characterizes the original B. striata plant, as well as seedling propagation techniques and its main cultivation modes, and discusses some problems in the B. striata production process. This work will provide a reference for industry development and the promotion of B. striata.

Establishment of a Rapid Breeding System for Bletilla Striata

“…It is a common experimental method to optimize the culture medium using the orthogonal test method. Zhang selected 1/2 MS medium as the basic medium, with 1% NaClO, 2% sucrose, and 0.1% activated carbon, with which the seed germination rate of B. striata attained 80% (Zhang et al 2019). In our experiment, we found that the optimal media ratio for seed germination was MS + 6-BA (2.0 mg/L) + NAA (1.0mg/L), under which the germination rate was effectively improved up to 91.8%.…”

Asymbiotic Germination and Seedling Development of Terrestrial Orchid Bletilla striata Using in vitro and ex vitro Cultures

“…After tubers are collected from the plant, they are peeled and dried. People use that plant for bleeding, muscular damage, burns, skin wounds, ulcers and, liver tumours (Xiang et al, 2013;Wang et al, 2013;Peng et al, 2014;Zhang et al, 2019).…”

A Review of Isolation, Chemical Properties, and Bioactivities of Polysaccharides from Bletilla striata

“…f. (Orchidaceae), named "Bai Ji" in Chinese, belongs to the orchidaceous family and is distributed widely in eastern Asian countries, including China, North Korea, Japan, and Burma [1,2]. B. striata has been widely used in traditional Chinese herbal medicine (TCM) for thousands of years and is one of the "seven white" in ancient China, mainly distributed in the Qinling Mountains and Yangtze River region [3,4]. TCM holds that B. striata is bitter, astringent, neutral, and warm and has bioactivities in alimentary canal mucosal damage, ulcers, bleeding, bruises, and burns [4,5].…”

Also, the functions of hemostasis, detumescence, and improving one's health of B. striata were recorded by Chinese pharmacopeia (2010) [2,6].…”

“…Increasing numbers of modern chemical and pharmacological studies revealed that B. striata has many beneficial effects, including healing, hemostasis, antioxidation, antiinflammation, antifibrotic, and immunomodulatory activity in vitro [4,7,8]. These multiple pharmacological effects of B. striata are attributed to its various functional ingredients, such as polysaccharides, saponins, flavonoids, terpenoids, trace elements, and other chemicals [1,4], among which the polysaccharides (BSPs) have gradually received attention and are now considered to be the main active substance of B. striata for its beneficial effects [9][10][11]. BSPs isolated using different extraction and purification methods have been confirmed to be structurally diverse biomacromolecules with various functions [2].…”
