Effects of Planting Medium on the Propagation of Loquat (Eriobotrya japonica L.) from Cuttings and Seeds

Loquat (Eriobotrya japonica) has a great potential to be cultivated as a fruit crop in North Sumatra. In order to cultivate loquat, the availability of high-quality seedlings is becoming an essential factor. This research was aimed to determine the response of loquat’s seed, stem, and shoot cutting on various types of medium. The seed, stem, and shoots cutting of loquat were collected from North Sumatra. Three types of medium, i.e., humus + roasted rice husk (1:1), raw rice husk + sand (1:1), and humus + raw rice husk (1:1), were used during the experiment in Cibodas Botanical Garden. The results show that the highest percentage of seed germination on the 10th week after the plantation was humus + roasted rice husk (91.18%) and followed by humus + raw rice husk (77.78%) and raw rice husk + sand (69.44%). The combination of humus + roasted rice husk gave a significant effect on plant high (9.178a cm), the number of leaves (5.51a), length of leaves (8.36a), and width of leaves (3.78a) on the 12th week after plantation. Moreover, there were no significant differences between shoot cutting and stem cutting propagation on parameters survival rate and the number of buds.

High Quality Seed

The production of high-quality seed is the basis for a durable a profitable agriculture. After production, seed is processed, conditioned, stored, shipped and germinated. For quality assurance, seed quality has to be controlled at all steps of the production chain. Seed functioning is accompanied by programmed transitions from cell proliferation to quiescence upon maturation and from quiescence to reinitiation of cellular metabolism upon imbibition. Despite the obvious importance of these control mechanisms, very little information is available at the molecular level concerning those elements that regulate seed germination. In the present study, the induction of cell cycle activity and the regulation of ß-tubulin expression is related to the water content and other physical properties of the seed.

This study investigated the effects of potting media on seed germination and early seedling growth of Pterocarpus erinaceus Poir at the Forestry Nursery in Jos, Nigeria. Using Completely Randomized Design (CRD) with three replicates, laboratory-tested soil samples, top soil, sharp sand, sharp sand + top soil, sharp sand + top soil + cow dung and sharp sand + top soil + poultry droppings were used in various combinations to assess the growth parameters of P. erinaceus (germination percentage, emergence, plant height, number of leaves, length of leaves and stem diameter) for 12 weeks. Descriptive and inferential statistics were employed to analyze collected data. Result indicated that sharp sand + top soil + poultry droppings had the highest nitrogen concentration (2.19%), sharp sand + top soil + cow dung (2.07%), sharp sand + top soil (1.50%), top soil (0.72%) and Sharp sand (0.38%). Potting media with poultry droppings recorded an overall higher percentage germination of 42.9% by the end of the germination period. Analysis of variance (ANOVA) of collected data on combined soil aggregate on growth parameters indicated a significant (p<0.05) difference in plant height, number of leaves, leaf length and stem diameter. Potting with poultry dropping gave the best potting media growth results when compared to other treatments that enhanced seed germination and seedling growth of P. erinaceus. This superior observation of the poultry droppings incorporated potting mixtures over the cow dung provides an outstanding potentials to enhance P. erinaceus plantation establishment. Consequently, recommended for raising seedlings in the nursery as well as ensuring sustainable management.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

Different Doses

Anthurium maricense is a tropical ornamental species with great commercial potential in the areas of landscaping and potted foliage plants. One of the main obstacles in the production of micropropagated anthurium plantlets is its slow development and/or the low survival rate of the plantlets during the acclimatization stage. The use of slow-release fertilisers (SRF) can accelerate this process; however, there are no reports in the literature concerning this practice during acclimatization of micropropagated plantlets of this species. As such, in the present study, the effects of different doses of SRF on the development of micropropagated plantlets of Anthurium maricense were evaluated during the acclimatization stage in a screenhouse. The experiment was carried out in a completely randomised design, with five treatments and four replications of four plantlets per plot. The treatments comprised doses of 0.0, 2.5, 5.0, 7.5 and 10.0 kg m-3 of the SRF Osmocote® (NPK 15:9:12) added to the substrate. The variables under evaluation were the variation in plant height, in the number of leaves and in the area of the largest leaf, pot occupancy, net photosynthetic rate, internal carbon, and leaf temperature and moisture. The use of SRF promoted better development of the micropropagated plantlets of A. maricense during the acclimatization stage. Of the variables under analysis, the variation in the area of the largest leaf is the most important, since the commercial interest of the studied species is the foliage, which was at its maximum with an estimated dose of Osmocote® of 6.40 kg m-3.

Problematic Soil

Beach ridges interspersed with swales (BRIS) soil is identified as one of Malaysia's problematic soil since this type of soil contains a plethora portion of sand texture that contributes to water and nutrient leaching causes infertile soil. A polybag trial was conducted to evaluate the effects of wood vinegar and rice husk biochar on soil properties and growth performances of immature kenaf. The plant was arranged in a completely randomised design with four treatments and three replications. The factors taken for the experiment were four different media compositions, i.e., T1(control), T2(BRIS soil amended with wood vinegar, WV), T3(BRIS soil amended with rice husk biochar, RHB) and T4(BRIS soil amended with wood vinegar and rice husk biochar, WV+RHB). Rice husk biochar and a combination of wood vinegar with rice husk biochar significantly improved soil properties in terms of soil moisture content, organic matter, water retention and soil porosity, as well as significantly increased the kenaf stem diameter. However, there was no significant difference in plant height, number of leaves, leaves area and chlorophyll content on different treatments medium. In conclusion, the application of rice husk biochar and wood vinegar in this study enhanced BRIS soil properties and showed a positive effect on the growth of immature kenaf.

Spilanthes acmella (Asteraceae) is an endangered ornamental cum medicinal annual herb. This study reports on the effect of two arbuscular mycorrhizal fungi (Glomus mosseae and Acaulospora laevis) applied either alone or in combination on post-transplanting performance of micropropagated S. acmella. Complete plantlets of S. acmella were raised by direct organogenesis from nodal explants on Murashige and Skoog medium supplemented with various cytokinins. S. acmella plantlets responded to all three mycorrhizal treatments in a significantly different way. G. mosseae enhanced the survival rate of S. acmella plantlets to 100%. Plant height, plant spread, number of branches per plant, number of leaves per plant, leaf area, biomass production, and chlorophyll content were significantly higher in AM inoculated plantlets as compared to the uninoculated ones. This clearly demonstrates that AM inoculation improved not only the survival rate of micropropagated plantlets but also their growth and biomass yield.

The main propagation method of Cassia fistula is sowing seeds. The seed germination is usually low because of its impermeable hard coat. Therefore, this experiment evaluated the effects of TiO2 nanoparticles and scarification methods on seed germination and seedling growth in vitro condition. The tree seeds were treated with, hot water, H2SO4 (36N), and mechanical scarification and culture on ¼ MS salt mixture. The medium was supplemented with different concentrations of TiO2 nanoparticles. The results showed that the highest percentage and rate of germination was recorded in seeds treated with mechanical scarification. The highest shoot and root dry weight was recorded for seeds treated with mechanical scarification and grown on MS media supplemented with 1.5 mg/ml TiO2 nanoparticles. TiO2 nanoparticles did not show any significant effects on the percentage and rate of germination. Different growing soil mixtures had significant effects on the growth of the ex vitro transferred plantlets. Coco peat and peat moss mixture (1:1) was found to be more effective in increasing the number of leaves and root length of the seedlings.
