“…Furthermore, several studies have shown that small container size can restrict root growth and nutrient uptake, leading to reduced carbohydrate accumulation in leaves and an imbalanced source/sink ratio, which in turn can result in reduced shoot growth [53,54]. Kim et al [55] demonstrated that the biggest-sized container was favorable for plant growth, as it showed higher plant height, leaf number, leaf area, fresh weight and dry weight for the growth of tissue-culture-propagated apple rootstock plants. Therefore, further studies on acclimatization based on industry requirements are needed.…”

Studies on the morpho-physiology of cryo-derived pineapple plants after acclimatization have been quite limited. Therefore, in the present study, the morpho-anatomical and physiological characteristics of cryo-derived Ananas comosus var. comosus ‘MD-2’ plants after acclimatization were investigated. Plants obtained from cryopreserved and non-cryopreserved shoot tips, as well as in vitro stock cultures (control), showed similar morphological development (viz. plant height, number of leaves, D leaf length, D leaf width, D leaf area, diameter of stem base, number of roots, plant fresh weight and plant dry weight) to conventionally micropropagated and non-cryopreserved plants. The pineapple plantlets developed efficient anatomical leaf structures that allowed them to adapt to the transition process from in vitro to ex vitro. In all groups of plants, the content of water and chlorophylls (a, a + b, a/b) decreased during the first 15 days of acclimatization and then remained constant until the end of the evaluation. The mesophilic succulence index increased to its maximum value after 15 days, then decreased and remained constant up to 45 days. Although physiological indicators fluctuated during the 45 days of acclimatization, no differences were observed in any of the indicators evaluated when plantlets obtained from cryopreserved shoot tips were compared with controls. The results of the plants from cryopreserved shoot tips show that they switched from C3 to Crassulacean acid metabolism, which denoted metabolic stability during acclimatization.

“…Other studies also showed that variations in light availability among different plants influenced their enlargement when grown in soil (Shawon et al, 2021;Kim et al, 2022). Kim et al (2021) showed that the height of apple seedlings was statistically not different when they were grown in a substrate medium with the same light intensity provided. In this study, we used light-emitting diodes (LEDs) emitting white light and the same light intensity for all treatments under controlled environmental conditions.…”

Substrates are important for plant growth as they maintain the water quality in an aquaponic system. The aim of this study was to investigate the effects of four inorganic substrates of sponge (S S ), orchid stone (S O ), hydroball (S H ), and volcanic rock (S V ) on an aquaponic system for planterior (use of plants in interior design) purposes. A recycling deep flow system was used. Kalanchoe blossfeldiana 'Peperu' seedlings and goldfish (Carassius auratus auratus) were kept together for 50 days in a small tank divided into two sections. Every day, 0.25 g of fish feed was supplied into each tank. The electrical conductivity (EC) and pH of the water were checked regularly. The nutrient concentration of the aquaponics water and the plant growth parameters were measured. The results showed that the increasing pattern of the EC strength over time was identical under the different treatments. The pH of the water fluctuated with different ranges for each treatment. Furthermore, the NH 4 + concentration in aquaponic water increased sharply from 15 to 20 days in all treatments, later becoming more stable. The NO 3 and Mg 2+ ion concentrations also sharply increased after 15 to 20 days of treatment; later, NO 3 was found to have increased in the S H , S S , and S O treatments.However, at 35 days after treatment, Mg 2+ and Ca 2+ showed a similar stable concentration trend in all treatments. An inverse relationship was observed between the Ca 2+ and HPO 4 2concentrations in all treatments. Plant heights, widths, and stem diameters of K. blossfeldiana were not significantly different among the treatments. The number of leaves, the leaf length, and the leaf width of the plants were also not statistically different among the treatments. At 50 days after the commencement of treatment, the SPAD value of plants was higher in the S H treatment than in the others. Furthermore, the numbers of branches, nodes, and flowers of plant were not significantly different among the treatments. These results indicate that the inorganic sponge, orchid stone, hydroball, and volcanic rock substrates influenced the EC, pH, and ion concentrations in aquaponics water. In addition, the period of the first 20 days is crucial to ensure stable ion concentrations in water. However, these substrates did not significantly affect the growth of K. blossfeldiana.

“…The root architecture is also impacted by the shade. This may be due to the lower thermal conductivity resulting from lower lighting that declines the shaded compartment temperature, then restricts root development [71]. Only the root length trait was higher in the 40%-and 80%-shaded plants compared to 0%.…”

The production of argan seedlings in nurseries is considered a crucial step for the success of any argan forest regeneration program since it increases the rate of survival and growth. Therefore, the substrate and container play a vital role in argan seedling production, while the use of shade may improve soil moisture and decrease the water stress of the plant. This study aims to determine the effects of these factors and their interactions. For this, the effects of four shade levels (0%, 20%, 40%, and 80%) and six different compositions of the substrate, as well as four different sizes and forms of containers, on argan seedling production were studied for six months under greenhouse conditions, based on analyzing the leaf mineral elements and measuring morphological traits. According to the studied parameters, the results show that 0% and 40% of shade are, respectively, the best shade levels for growth, while the germination rate is higher only in an unshaded compartment (85.28%). Furthermore, the substrate based on peat moss lead to one of the higher germination rates (78.75%) and the finest plants in terms of chlorophyll content, and shoot and root growth, while the largest container (C2) had the best shoot and root growth with 34.34 cm of root length. However, the mineral analysis, mainly the leaf total nitrogen concentration, is correlated with morphological traits. In addition, the cost–benefit analysis study confirmed this finding and valorizes the use of S1 substrate (1/2 black peat and 1/2 blond peat) and a C2 container (volume: 3100 mL) since it is considered the most efficient and economic combination for different shade levels.
