“…Peptone was also responsible for increased uniformity of seedling development. Niacin has also been found to be beneficial for orchid seed germination (Arditti, 1967). Niacin and its derivatives are essential for metabolism as components of NAD + and NADP + .…”

A major obstacle to native orchid production is difficulty in seed germination. Culture media and light effects on seed germination of Calopogon tuberosus var. tuberosus, a native orchid with horticultural potential, were studied. Culture media included Knudson C, Malmgren modified terrestrial orchid, and PhytoTechnology orchid seed sowing. Effects of 8 weeks continual darkness, 8 weeks 16-h photoperiod, 2 weeks dark followed by 6 weeks 16-h photoperiod, 4 weeks dark followed by 4 weeks 16-h photoperiod, and 6 weeks dark followed by 2 weeks 16-h photoperiod were examined. Percent seed germination was highest on Knudson C after 8 weeks culture; however, seedling development was enhanced on PhytoTechnology seed sowing medium during 8 weeks culture under a 16-h photoperiod. This suggests that while KC and darkness promoted seed germination, P723 and light enhanced further seedling development. Seedlings of C. tuberosus readily acclimated to greenhouse conditions. Abbreviations: KC -Knudson C; MM -Malmgren modified terrestrial orchid medium; NAD -nicotinamide adenine dinucleotide; NADP -nicotinamide adenine dinucleotide phosphate; P723 -Phyto Technology orchid seed sowing medium

“…3.2.3. Effect of Jrhs Proliferation on Media Containing Proteins, Amino Acids, B Vitamins, and Plant Growth Regulators Nitrogen or amino acids brought many benefits to growth or morphogenesis, including increased callus formation, prevention of browning, and increased protocorm-like bodies, seedlings and the yield of orchids [17,[42][43][44].…”

“…Jrhs that cultured with 1 g/L tryptone obtained significantly (p < 0.05) larger size and better proliferation rate, which were 8.9 ± 2.0 mm and 12.4, respectively. Tryptone is mainly composed of amino acids and vitamins [42]. Related research data showed that 2 g/L tryptone in the culture medium could help the development of Paphiopedilum primulinum and Phaius tankervilliae seeds [29,45] as well.…”

Effects of Nutrients and Growth Regulators on Seed Germination and Development of Juvenile Rhizome Proliferation of Gastrodia elata In Vitro

Two prevalent issues with Gastrodia elata growing in a natural wild environment are the necessary symbiotic seed germination with Mycena spp. and the long growing cycle of protocorms into mature rhizomes with Armillaria mellea. This study explored the most suitable nutrients to germinate seeds and the developmental stages and propagated protocorm/juvenile rhizomes (jrhs) through a tissue culture approach. Adding humic acid, mashed potato, peptone, and (indole-3-acetic acid) IAA to the 2 g/L Hyponex 7-6-19 basal medium accelerated seed germination into protocorms with an average length of 2 mm. The nutrients best for the in vitro propagation of jrhs consisted of 1 g/L Hyponex 7-6-19 and MS salts with 1/2 NH4NO3 and KNO3, 2 mg/L BA, 2 mg/L NAA, 2 g/L tryptone, 2 g/L glutamic acid, 1 g/L chitosan, 10 g/L apple puree, 20 g/L mashed potato, 100 mL/L coconut water, and 1.5 g/L A. mellea powder, at a pH level of 6. The maximum length and number of jrhs were 17.2 ± 0.8 mm and 76.6, respectively, in two subcultures. The in vitro propagation system started from seeds of G. elata can be employed as a potential method to propagate protocorm/jrhs for the cultivation of mature rhizomes from indoor or outdoor cultures.

In Callleya attrantiaca seedlings, ethephon _(2-chloroethylphosphonic acid, also known as Ethrel), slightly :icc~l~rated leaf development at c~ncentratlons between 2.5 and 20 ppm but suppressed it at 50 ppm. It inh1b1t~d leaf l~ng~h. at concentrations .of 2.5\ 5, and SO ppm but enh:inced it at 10 and 20 ppm. Root formation was mh1b1ted by concentrations higher than 2.5 ppm. Chlorophyll content of seedlings was highest on a medium containing S ppm ethephon.
