The Way

This paper proposes a flexible hose-like fluid actuator to inspect narrow curved or bumpy terrain. The tip alone moves forward and the rest remains stationary, enabling the actuator to move smoothly without interfering with the outer environment – a concept based on the plant growth process. The actuator consists of multiple flexible flat tubes bent in the skin, whose bending point is involved in preventing fluid from passing through. The actuator can also steer the direction in which the tip lengthens, while the shape of the rest remains unchanged. Our Grow-hose-I prototype is 62 mm in diameter and grows at a maximum speed of 500 mm/s while producing a 45 N drive. The way of carrying a head unit equipped with a camera is discussed and feasibility of the actuator’s inspection on narrow terrain is demonstrated.

Low temperature is one of the major adverse climatic factors that suppress plant growth and sustainable agricultural development. In these climate conditions, silicon (Si) can mitigate various abiotic stresses including low temperature. In this study, the roles of foliar-applied silicon (10 mM potassium metasilicate) in enhancing tolerance to chilling stress were investigated in maize (<em>Zea mays</em> ‘Fajr’) plants. The low temperature stress caused significant reduction of plant growth and relative water content; however, Si ameliorated these effects. Si supply in maize exhibited a significantly positive effect on accumulation of free amino acids, and reduced the necrotic leaf area. The decrease in maximum quantum yield of PSII (F<sub>v</sub>/F<sub>m</sub>) was reversible during recovery, but not in the non-Si-treated leaves. This can be explained by enhancement of protective pigments; carotenoid and anthocyanin leading to the protection of PSII from damage. Additionally, analysis of OJIP transients revealed that Si reduced cold damaging effect on performance index (PI<sub>abs</sub>) and F<sub>v</sub>/F<sub>m</sub> through improvement of excitation energy trapping (TR<sub>0</sub>/CS) and electron transport (ET<sub>0</sub>/CS) per excited cross-section of leaf. The malondialdehyde (MDA) concentration, which was significantly increased under chilling stress, was decreased by Si. The reduced glutathione and ascorbate concentrations were higher in Si-treated plants as compared to those without application of Si under chilling stress. These results indicated that Si could enhance the chilling stress tolerance of maize plants through improving the biomass accumulation, maintaining a high level of glutathione, ascorbic acid, protein, protective pigments, and enhancing the photochemical reactions. This study also suggests that the foliar-applied Si increases recovery ability from chilling injury.

A quantitative description of primary growth from the apical meristem activity is proposed for four tropical plants: Alstonia vieillardii var. vieillardii (Apocynaceae), Miconia ciliata (Melastomaceae), Ricinus communis (Euphorbiaceae), and Solanum rugosum (Solanaceae). The development of these four plants corresponds to Leeuwenberg's model. Three parameters were measured at different stages of plant growth: leaf surface, length of the underlying internode, and the surface of the internode section. Two other parameters were derived from these three: parameter T, which summarizes the first three parameters and corresponds to the overall dimension of the leaf–internode system, and parameter D, showing the differential evolution of the leaf surface and the corresponding axial volume. The higher the D value, the higher the predominance shown by the twig over the leaf component. This phenomenon is named axialization. The reciprocal situation is called foliarization. For parameter T, the observed variations are present in all four species and showed an increase followed by a decrease in dimensions during the growth process. From the evolution of parameter D, two processses can be recognized. In A. vieillardii var. vieillardii and Solanum rugosum, the amplitude of variation is wide and can be compared with that of parameter T. In M. ciliata and R. communis, the amplitude of variation is significantly reduced. A link can be established between this morphometric evolution and flowering. The results obtained for these four species are compared with those obtained by other researchers and bring new elements to the study of the relationship between the vegetative evolution of the plant and its flowering. Key words: architecture, morphometry, Leeuwenberg's model, ontogeny. [Journal translation]

Pear Orchard

Plant growth regulators (PGRs) are described in the literature as having a significant role in securing crop management of modern agriculture in conditions of abiotic and biotic stressors. A joint field experiment was carried out to assess the role of seaweed-based extracts in pear trees and to test the “less for more” theory, which consists of getting more and better agricultural produce using fewer innovative inputs. The trials took place on two production seasons (from March till September 2018–2019) and the selected case study was on a pear orchard (Pyrus communis L. cv. Abate Fètel) in Emilia Romagna (Italy) by Fondazione Navarra and Timac Agro Italia S.p.A. Results demonstrate that, depending on the yearly climate conditions, it was possible to substantially reduce the primary nutrients by 35–46% and total fertilisation units applied by 13% and significantly improve quantitative and qualitative production indicators (average weight of fruits (5%) and total yield (19–55%)). Results also confirm a positive correlation between plant growth regulators and agronomic efficiency of pears which increased between five and nine times compared to the conventional nutrition programme. These outcomes constitute scientific evidence for decision making in farm management.
