Meizotropis pellita is a rare, endangered and threatened plant species found in Patwadanger forest. In nature this species grows from rootstock in precise and sensitive habitats. However, phenolic compounds provoke browning reaction which is responsible for lethal browning in plant tissue culture and hindering in vitro germination. The aim of this study was to minimize the effect of phenolic compound during seed germination. We evaluate different antibrowning treatments in Meizotropis pellita seeds. The seeds were pretreated in Polyvinylpyrrolidone and then treated seeds were cultured on MS media and sterilized seeds were directly inoculated on PVP containing MS media. These culture media incubate under dark and light conditions at different durations respectively. Our results showed that addition of antibrowning agent, PVP inhibit onset of browning. Dark and light condition also played a crucial role on onset of browning. Delayed and low intensity of browning were observed in case of seeds that were inoculated on MS media containing PVP and were kept in dark. The present research offers a positive in vitro seed germination protocol for Meizotropis pellita conservation.

ABSTRACT Some factors may influence the in vitro culture of native orchids, especially the culture medium, sealing system and light condition. This study aimed to evaluate the addition of banana pulp and peel in the formulation of culture media, sealing system and irradiance, in the in vitro growth of Cattleya nobilior Rchb. f. A completely randomized design was used in a factorial scheme with five culture media [Murashige & Skoog supplemented or not with banana pulp or peel (100 or 200g L-1)], two light conditions [3,000 K LED lamps (43 µmol m-2 s-1 or 86 µmol m-2 s-1)] and two sealing systems (natural and conventional ventilation), with six replicates of one vial each. The plant height, diameter of the largest pseudobulb, length of the largest root and of the largest leaf, fresh weight and number of leaves, roots and shoots were evaluated. The use of both the banana pulp and peel as additives in the culture medium formulation promoted the C. nobilior growth. The natural ventilation system increased the plant height, pseudobulb diameter and leaf length, while the conventional system promoted tillering.

The objectives of this study were to determine the effects of yellow light (Y), green light (G), and two blue lights (B) at different wavelengths in conjunction with red light (R) on the growth and morphogenesis of potato plantlets in vitro. Randomized nodal explants were cut into 1.0–1.5 cm pieces and were grown under five different light conditions: fluorescent white light (FL); the combined spectra of R, Y, and B at 445 nm (R630B445Y); the combined spectra of R, G, and B at 445 nm (R630B445G); the combined spectra of R, Y, and B at 465 nm (R630B465Y); and the combined spectra of R, G, and B at 465 nm (R630B465G). Morphogenesis and physiological parameters were investigated. The results showed that R630B445Y and R630B465Y increased the fresh weight (FW), dry weight (DW), stem diameter, blade number, leaf area, specific leaf weight (SLW), and the health index of potato plantlets in vitro; root activity increased significantly; and soluble sugar, soluble protein, and starch also increased. The addition of Y to the combined spectra of R and B contributed to the growth, development, and morphogenesis more than the combined spectra of R and B with G, and B at 445 nm was more effective at promoting plant growth than was B at 465 nm.
