Opis:
Invasive alien species are non-native plant species that displace native species and pose adverse effects to environment, ecosystem, economy, and human health by diminishing the growth of native plants and by exhibiting higher stress tolerance. In our present study, four invasive alien species, namely Lantana camara, Parthenium hysterophorous, Ricinus communis, and Ageratum conyzoides, were studied from different locations. Plants growing under natural environmental conditions were sampled at random in the vicinity of Jalandhar. To gain insights into the biochemical basis of invasiveness of these plants, the samples were subjected to chemical fingerprinting by using UV-Vis, fluorescent, and Fourier transform-infrared (FT-IR) techniques under natural abiotic stress conditions (moderate and hot conditions). Indices of oxidative stress, such as malondialdehyde (MDA), were also studied. MDA levels were enhanced under hot conditions. Elevated peaks (major and minor) were observed in UV fingerprinting during adverse abiotic conditions. Fluorescent spectroscopy also validated the enhanced levels of secondary metabolites. FT-IR spectroscopy confirmed the presence of alkaloids and phenolics during stress conditions. Peaks were identified as rutin, vanillic acid, ascorbic acid, and glutathione reduced. The obtained results showed that under stressful conditions, the studied plants may produce an increased level of metabolites that might play a role in minimizing the oxidative stress faced by these plants. It was concluded that the studied plants, namely P. hysterophorus, L. camara, R. communis, and A. conyzoides, have the potential to cope with abiotic stress such as high temperature, which could be the reason for their invasiveness and vast adaptability.

Opis:
In vitro tissue culture technique, especially micropropagation, is attracting increasing attention in the production of ornamental plants. This technique will probably dominate the horticultural market in the near future. Light is one of the several factors affecting the success of in vitro plant tissue cultures. It directly affects the widely understood morphogenetic response of the explant, i.e., the ability of the explant to grow or regenerate, produce roots, etc. Lighting conditions provided during the in vitro stage may also greatly affect the plant vigor after transferring to nonsterile conditions. Moreover, the necessity of providing artificial light significantly contributes to the total cost of maintaining tissue cultures (related to energy consumption and the need to cool down the heat generated by lamps). Light quantity (intensity) and quality (spectral composition) are the two main parameters that determine its influence on in vitro cultures. This impact depends on the species and other accompanying factors. The aim of this mini-review is to summarize information on the influence of light on the morphogenetic and biochemical response of explants of some selected ornamental plant species grown under in vitro conditions.
