“…The level of incident solar radiation may affect the physiological processes of cuttings and the early development of plants [12]. Literature indicates that cuttings propagated by Ficus carica L. [13] and Cornus alba L. [14] responded differently to shade levels but works with A. citrodora were not found, making it necessary to study and to investigate the light regimes in the cuttings production phase and the acclimatization processes.…”

Aims: The aim of this study was to evaluate the effect of types of cuttings and light intensity on cidró vegetative propagation. Place and Duration of Study: Medicinal Plants Garden, Federal University of Grande Dourados (UFGD), Dourados, state of Mato Grosso do Sul, Brazil, September to November 2016. Methodology: The experiment was carried out under two light conditions (shaded and full light), evaluating three types of cuttings (softwood, semi-hardwood and hardwood). Experimental design was a 2 x 3 factorial randomized complete block design (RCBD) with four replications. Results: Hardwood cuttings showed the highest survival rates (86% and 82%), regardless of light. Highest fresh weight (0.6062 g plant-1) and dry mass (0.2987 g plant-1) with a leaf of 44.57 cm2 were from hardwood cuttings, regardless of the light, while the longest root length were those of softwood cuttings under full light. Physiological indices varied as a function of light intensity, The highest values of leaf area ratio (46.11 cm2 g-1) and specific leaf mass (0.0037 g cm-2) occurred in cuttings under full light. Conclusion: The vegetative propagation of cidró can be carried out using the hardwood portion of the cutting branch, under full light.

“…Another explanation could be that the stimulation of signal molecules, such as the plant hormone indole-3-acetic acid (IAA), may have increased the proportion of fine roots of P. orientalis under AP. It was recently reported that high concentrations of IAA could stimulate the formation of fine roots when the taproot length was restricted (Pacholczak et al, 2017;Pierret et al, 2007;Remans et al, 2008;Spaepen et al, 2007). Furthermore, we suggest that the enlarged taproot cross-section in response to AP might be attributed to the increased cortical thickness within the root crosssections of P. orientalis.…”

Additional index words. air-root pruning, root growth, chinese cypress Abstract. Air-root pruning (AP) has been identified as an effective technique for enhancing root growth and development. However, little information is available regarding the temporal changes in the root system of Platycladus orientalis (L.) Franco under AP. We performed integrated morphological, physiological, and anatomical analyses of the roots in P. orientalis seedlings that had been air-root pruned for 120, 150, and 190 days. Our results found that the whole root length, number of root tips, and root surface area of AP seedlings at 120, 150, and 190 days were higher than those of the non-root-pruned (NP) seedlings (P < 0.05), but the average root diameter did not differ significantly between the treatments. Compared with NP treatment, AP increased the root length, surface area, number of tips, and specific root length of the £0.5 mm diameter roots in P. orientalis during the experimental periods (P < 0.05), but those of 0.5-to 1-mm-diameter roots were only increased on day 190 (P < 0.05). The AP plants also exhibited higher root vitality and proportion of live fine roots than the NP plants (P < 0.05). Our anatomical evaluation of the £0.5 mm roots and taproots revealed features that could account for the morphological differences found between the AP and NP plants. In conclusion, our results indicate that air-root pruning induced changes in the roots that promote the root system development in P. orientalis compared with the NP treatment during the experimental period. These results thus provide experimental evidence to support the use of AP in P. orientalis seedlings.

“…The microbiological method of protecting and stimulating plants was originally developed in the field of agriculture, but is now applied to forest and ornamental tree species (Gorb & Barayshchuk, 2019;Lekontseva et al, 2019;Pacholczak et al, 2017). The basis of microbiological preparations are producer strains and their metabolic products: enzymes, antibiotics, siderophores, hormones.…”
