“…In the majority of the current experiments, the use or lack of use of mycorrhizae had little or no effect on the mean root length, root number and rooting rate. The rooting response of the cuttings of shrub species to mycorrhizae has been suggested to depend, among other things, on the type of substrate, genotype and the applied fungal strain [36,37,46]. From the current results, it is not clear whether the lack of a mycorrhizal effect observed is due to the applied substrate or the genetic make-up of the tissue, which requires further research at the biochemical level.…”

“…A further example of natural plant extracts that contain natural auxin substances is aloe vera gel [35]. Apart from substances with rooting enhancing properties, the use of arbuscular mycorrhizal fungi (AMF) as alternative rooting enhancers in asexual plant propagation has also been evaluated and discussed in the past [36], taking advantage of the natural properties of arbuscular mycorrhizal fungi in enhancing plant growth and development or acting as natural bio-fertilizers [37].…”

The current study aimed to enhance the sustainable utilization framework of the underutilized Greek native Rosa canina L. (rosehip) germplasm as a potential novel crop that can deliver high-quality products with minimum environmental impact. The first part of the work includes asexual propagation trials on cuttings of two Greek R. canina genotypes, assessing the potential of various alternative rooting enhancers to the conventionally used indole-3-butyric acid (IBA), as affected by rooting substrate and cutting type. The propagation results showed commercially acceptable (>50%) rooting rates for 2500 ppm IBA, coconut water, rooting gel and aloe vera treatments and similar rooting attributes of root number and length, providing evidence for the feasibility of using alternative rooting enhancers. The second part of the work presents the results of an ongoing ex situ cultivation trial assessing the potential of a diversified organic fertilization regime against conventional fertilization on fruit size and yield, coupled with macro- and micro-nutrient concentration, in the leaves of four Greek R. canina genotypes. The results showed a genotype-specific response in rosehip fruit size and yield to fertilization, with the organic regime showing comparable results to the conventional fertilization. In addition, diverse patterns, depending on the element, of macro- and micro-nutrient content were measured in the leaves in both fertilization regimes, which were, however, genotype-dependent. Overall, the current study reports for the first time the potential of alternative rooting enhancers for commercial R. canina propagation coupled with the application of organic fertilization as a means of establishing a diversified cultivation protocol for underutilized R. canina germplasm. The current results can be employed to further facilitate a value chain creation for Greek rosehips as a raw material for use in the agro-alimentary and medicinal–cosmetic sectors.

“…To date, nobody has shown any mycorrhizal associations with M. scabra, including Arbuscular Mycorrhizal Fungi (AMF), ectomycorrhizal fungi, or endophytes. Studies presented by Ravi & Muthukumar showed that M. scabra grafted onto rootstock of Cucurbita moschata x Cucurbita maxima that was inoculated with AMF showed increased vigor, production, and quality of fruit (Ravi & Muthukumar 2019). Ravi & Muthukumar did not provide any insight into the mycorrhizal associations with M. scabra.…”

This manuscript attempts to bringMelothria scabra[Naudin] to the attention of agronomic researchers as an increasingly popularand economically important crop and to identify gaps in research that should beinvestigatedwithfuturestudies.Allrelevantpeerreviewedpublications were examined in this study, with 79% of the studies published since 2000 c.e., while the remainder of the studies provide historical context.Major gaps in the research involvingM. scabraoffers a new frontier in agronomic studies, and will increase agronomist’s knowledge of this uniquely meso-American crop species. In conclusion,M. scabrais an understudied crop with world-widecultivation, and offers many opportunities foragronomists to research the genetics, physiology, and morphology of this small melon

Microorganisms play an important role in the propagation and growth of plants. Propagation of plants through stem cuttings is a popular method widely practiced in horticulture and forestry. As the information on the interactive role of arbuscular mycorrhizal (AM) fungi and phosphate-solubilizing bacteria (PSB) in the regeneration and growth of clonally propagated plants is limited, we inoculated stem cuttings of Impatiens walleriana with Rhizophagus fasciculatus and Bacillus megaterium var. phosphaticum individually or in combination in an unsterile Alfisol field soil. The inoculated cuttings were harvested after 45 days of cultivation and various growth parameters and phosphorus (P) uptake were measured. Inoculation with the AM fungus or PSB individually improved plant growth parameters, whereas the dual inoculation did not give synergistic results. Plants inoculated at cutting stage with R. fasciculatus accumulated the highest plant biomass and showed maximum microbial inoculation effect and efficiency of P uptake. Inoculation with the PSB stimulated symbiosis with native AM fungi but a synergistic effect has not been found when both AM fungi and PSB were co-inoculated. It could be concluded that screening for compatibility between microorganisms is essential before selecting the bioinoculants for dual inoculation.
