“…The shoot canopy varied based upon the mineral formulation in sterile culture, so plants were better apt to capture light and grow more rapidly in later replicates with brighter sunlight. Subsequent effects of media composition used in sterile culture effected canopy size and greenhouse growth in turmeric with the effects of in vitro mineral nutrition becoming evident during acclimatization [ 21 ]. Likewise, reports of varying responses in vitro and ex vitro growth based upon mineral nutrition has also been described in Lemna minor and Landoltia punctata [ 22 ].…”

Difficult-to-root plants often perform poorly during acclimatization and in vitro rooting can increase the survival and quality of plants. The influence of auxin application and mineral nutrition on in vitro rooting and subsequent effects on plant quality in eight Prunus genotypes were investigated. Microshoots were rooted in vitro on Murashige and Skoog (MS), ½ MS, Driver and Kuniyuki (DKW), or New Prunus Medium (NPM) media formulations in combination with 15 µM indole-3-butyric acid (IBA), 4-day 15 µM IBA pulse, 1 mM 30 s quick-dip, or IBA-free treatments. Shoots were observed pre- and post-acclimatization to determine rooting methods to maximize quality and minimize labor. A genotype-specific response to auxin application was observed with seven of eight genotypes achieving 100% survival when paired with the recommended IBA treatment. Peaches performed best when treated with 4-day IBA pulse or 30 s quick-dip. Rooting of P. cerasifera, it’s hybrid to P. persica, and P. munsoniana all benefitted from IBA application. Shoots rooted with 15 µM IBA were smaller and lower quality in most genotypes. DKW maximized size and quality in six genotypes. Better shoots and larger root systems during in vitro rooting produced better plants in the greenhouse with no detrimental effect of callus growth. Rooting techniques to maximize plant quality while reducing labor are specified.

“…The short (Mweru) and medium (Kampolombo) duration varieties achieving maximum shoot biomasses at higher fertigation treatments than the long‐duration variety (Nalumino) was perhaps due to their internal demand for nutrients to complete their growth cycle within the shortest period. El‐Hawaz et al () and Kanmegne et al () indicated that nutrition accelerates growth, thus, could be used to shorten the growth cycle. Certainly this was the case in the three varieties but more pronounced in Mweru.…”

Response of cassava (Manihot esculenta Crantz) to fertigation as a form of nutrient delivery is unknown. The objectives of this study were to establish a balanced nutrition and to enhance agronomic nutrient use efficiency (ANUE) of cassava under fertigation. This study was conducted in the greenhouse and in the field. In both, the results showed a similar trend. There were six fertigation concentrations and three cassava varieties, selected for their duration of growth in the field. Shoot biomass of the long‐duration variety (Nalumino) was the highest, even though its dry root yield was the lowest (10.18 t ha−1) among the varieties. In contrast, the medium‐duration variety (Kampolombo) produced the highest dry root yield (20.34 t ha−1) and a lower shoot biomass. The highest root yield of the shortest‐duration variety (Mweru) was achieved at 200 mg N, 30 mg P, and 200 mg K L−1 (155.0, 23.3, 155.0 kg N, P, K ha−1), while Nalumino's was at 70 mg N, 7 mg P, and 70 mg K L−1 (54.3, 5.4, 54.3 kg N, P, K ha−1). ANUE and harvest index of these varieties declined as the fertigation concentrations increased. Additionally, the correlation between concentrations of N in the youngest fully expanded leaf (YFEL) blades and dry root yields was the lowest (R2 = 0.5488), whereas P and K were R2 = 0.7237 and R2 = 0.8006, respectively, an indication that nutrient concentrations in the leaf, especially N, cannot easily be used to predict root yield. When cassava reaches nutrient sufficiency, mainly N, its accumulation in the leaf continues without significant increase in the root yield.

“…Turmeric plants cultivated in vitro in the absence of NH4 + and with high concentrations of calcium, had the largest growth compared to plants produced in MS medium with 100% of the concentration of ammonium (Adelberg et al, 2013). The reduction of cationic nitrogen in the MS medium also favored the growth in height during the acclimatization of turmeric plants (El-Hawaz et al, 2016).…”

Dragon's blood, native species from South America, has therapeutic properties scientifically proved. This study had the objective of developing a protocol for in vitro establishment and plantlets acclimatization from zygotic embryos, since researches with species are incipient. Culture media (MS, WPM, QL and N6) were assessed, without and with activated charcoal (2 g L-1). It was observed the percentage of developed embryos from 83% to 100% and the effect of medium composition for plant height and leaf number in vitro. The plantlets were acclimatized with 100% of survival rate, and for treatments from in vitro culture only the culture medium influenced diameter and plant height. The WPM and QL formulations without activated charcoal are indicated for in vitro culture of embryos and acclimatization of Dragon blood. The suggested methodology represents an important strategy for reproduction, physiological study and preservation of species.
