“…A significant common response was observed during the application of both the hormones, i.e., with gradual rise in application of both the hormones, there was a moderate fall in the positive response of root growth from the cultured shoots. Thus, it was evident from the current study that application of NAA for proper root growth was more beneficial than that of the IBA application (34)(35)(36).…”

In the present investigation, a micropropagation protocol has been developed for Vanilla borneensis Rolfe – a critically endangered orchid through multiple shoot regeneration. Through in vitro multiple shoot regeneration from both nodal and shoot tip explants, maximum (100%) shoot induction was observed. The minimum time required for shoot bud induction was observed from the shoot tip (5–7 days) on medium supplemented with BAP (4.44 mM) + KIN (2.32 mM) as compared to the nodal explants. Maximum multiple shoot regeneration was observed from nodal explants on the medium supplemented with BAP (4.44 mM) + TDZ (6.82 mM). However, maximum shoot length was observed on the medium supplemented with BAP (4.44 mM) + 15% CW and the number of nodes (5.27±0.33) per shoot after 90 days. Maximum (80-100%) of root initiation was observed in almost all the concentrations of NAA. The shortest time of root initiation was found on the medium supplemented with NAA (5.37 mM). Further, acclimatization period was found to be 15 days with 70% acclimatization while 60% of survivability was observed in the field condition. This efficient micropropagation method of V. borneensis could be successfully used for mass propagation as well as conservation of the critically endangered wild orchid.

“…ex Hook.f. a rare endemic species in the Indian Thar Desert, that is of immense economic value and ecological importance (Singh et al, 2017;Parihar & Dwivedi, 2020) for its in-situ conservation. Not only this, preliminary/ reconnaissance survey also revealed distinct variability in its morphology also making it all the more necessary to conserve it.…”

“…Consequently, its populations are becomingsmaller in size occurring in isolated patches scattered far and wide over rocky plateau in Jaisalmer district of India. Parihar and Dwivedi (2020) reported successful multiplication of G. varians through tissue culture means; however, results of its hardening and success rate of field plantation for exsitu conservation are not known so far. Hence, in-situ conservation of G. varians was considered a viable proposition for testing in the field.…”

This study assessed natural diversity of rare, endemic and threatened arid plant, i.e., Glossonema varians, in the Indian Thar desert and that needs in-situ conservation. Furthermore, efficacy of a traditional method of rainwater conservation is investigated in sustaining its regeneration and conservation. Two biotypes of G. variancs on rocky crevices having crisped margin leaves with light yellow flowers and sand deposition having leaf margin entire and dark yellow flowers are found. Ecologically, it is a sub-dominant species with relative importance value raging from 8.71 to 49. Box-whisker plots revealed that rainwater conservation improved plant growth and population of G. varians. Results of t-test further evidenced the influence of rainwater conservation in regenerating and flourishing plants of G. varians. Rainfall and plant population showed a moderately positive linear relationship (R2 = 0.30, p<0.10) and 27-mm threshold rainfall over 6 days is essential for conserving G. varians.

“…The selection of media depends on the plant species and its growth patterns in the natural environment. Some traditional media like Murashige and Skoog's Medium (1962) is used to develop in vitro culture of some plants like Caralluma edulis (Parihar, 2016(Parihar, , 2018Parihar and Dwivedi, 2019), Ceropegia bulbosa (Parihar, 2017), Glossonema varians (Parihar, 2020;Parihar and Dwivedi, 2020), Stevia rebaudiana (Mathur et al, 2017). Zarrouk's medium was initially synthesized as a synthetic medium by Zarrouk in 1966 that is still utilized in the form of a standard media.…”

Background: Spirulina is a multicellular, filamentous cyanobacterium, belonging to the Phormidiaceae family which appears as blue-green filaments composed of cylindrical cells arranged in unbranched helicoidal trichomes. It contains a wide spectrum of nutrients that include proteins with all essential amino acids, carbohydrates, vitamins, minerals, pigments, carotenoids and super antioxidants apart from trace elements. Methods: The aim of the present study is to optimize the growth of cyanobacterium i.e., Spirulina platensis in selected media such as Zarrouk’s modified medium, Zarrouk’s medium, BG11 medium and F-2 medium. The growth analyses were recognized after 30 days. The temperature was maintained at 30±2°C under 12:12 hour light-dark cycles, light illuminated (4500 lux). Result: The maximum biomass of 0.641 gm/ml was achieved in Zarrouk’s modified medium. The inoculation of S. platensis in the F-2 medium showed the least growth of alga. The maximum concentration of phycocyanin content (0.19 mg/ml) and total carotenoid contents (5.99 µg/ml) were observed in Zarrouk’s modified medium followed by Zarrouk’s medium (0.12 mg/ml and 5.51 µg/ml) and minimum amounts were observed in F-2 medium (0.08 mg/ml and 3.08 µg/ml). According to the results, this study concluded that the growth and biomass of Spirulina with significant cell count and higher pigment proteins can be enhanced by using the naturally modified medium.
