“…In general, plants have a higher WUE under drought conditions, and have conservative water-use strategies to maintain plant growth and development; furthermore, under adequate water-environmental conditions, a lower WUE can cause plants to obtain higher productive forces [ 36 , 37 ]. In a forest system, water-use efficiency is the key link between tree production and water management [ 38 ]. Understanding the water-use efficiency of plants can not only help to understand the survival and adaptation strategies of plants, but it can also aide in artificially regulating limited water resources to obtain the highest yield or economic benefit [ 38 , 39 ].…”

Ex situ conservation plays an important role in the conservation and utilization of plant resources. In recent years, botanical gardens have greatly improved the ex situ conservation of plants, and research has mainly focused on morphological characteristics, reproduction technology, and conservation value. There are few studies on the ecophysiological traits of plants after conservation. Forty-seven plants that are frequently used in North China and were grown in the Beijing Botanic Garden were selected to measure their photosynthetic traits, light-use efficiency (LUE), water–use efficiency (WUE), specific leaf area (SLA), relative chlorophyll content (SPAD), and leaf water potential (φ). An analysis of variance showed that there were significant differences in the ecophysiological traits of the leaves of 47 woody species. The light saturation point (LSP), net photosynthetic rate at light saturation (Pnmax), φ, and SLA had significant differences among different plant life forms. The SLA and SPAD of leaves were significantly different among the families. The LUE of all species reached its maximum under a low light intensity, and species with a large difference between the light saturation point and light compensation point had larger Pnmax values. This research further adds to the understanding of the adaptation mechanisms of plants to the environment under the conditions of a botanical garden as well as the environmental fitness in a long-term ex situ domestication and then helps with scientifically setting up artificial management conditions.

“…Furthermore, study approaches used for agricultural crops can be adapted or improved for eucalyptus. In particular, opportunities are related to tillage in compacted areas by forest harvesting, by previously defining different soil compaction states in the field, such as performed for agricultural crops (Secco et al, 2009), considering spatial variability in soil physical properties (Silva et al, 2003;Marins et al, 2018); short-and long-term tillage (Veiga et al, 2008(Veiga et al, , 2009(Veiga et al, , 2010Reichert et al, 2016c) and cropping systems effects (Awe et al, 2015;Cecagno et al, 2016;Ambus et al, 2018;Reichert et al, 2022); refinement of plant available water as affected by soils and tillage, using existing pedotranfer functions (Vaz et al, 2005;Reichert et al, 2009Reichert et al, , 2020b or by developing improved ones, as well as via soil water balance (Reichert et al, 2021d), forest hydrology (Ferreto et al, 2021a) or catchment water-budget fluxes (Reichert et al, 2017bEbling et al, 2021;Ferreto et al, 2021b;Valente et al, 2021).…”

“…Forestry is a key component of the ICLF system in that it provides various ecological and economic advantages by decreasing the kinetic energy of rainfall and reducing water runoff, enhancing infiltration into the soil (Reichert et al, 2021), improving nutrient cycling (Stieven et al, 2018), exploiting deeper soil layers, minimizing nutrient losses through leaching (Borges et al, 2019), mitigating greenhouse gas emissions (Freitas et al, 2020), reducing biodiversity loss (Santos et al, 2019) and diversifying agricultural production (Reis et al, 2021).…”

In integrated crop‐livestock‐forestry (ICLF) systems, an agroforestry model, the forestry component influences the distribution of photosynthetically active radiation (PAR) and alters grain productivity. The aim of this study was to evaluate the effects of systematic and selective thinning of eucalyptus stands on the productivity of soybean and maize grown. The randomized block‐designed experiment comprised three treatments, namely crops grown under full sunlight (CFS) and in ICLF plots subjected to systematic and selective thinning to leave single‐row (ICLFS) and triple‐row (ICLFT) tree configurations. Soybean and maize were planted in succession between the tree stands and PAR incidence/transmittance and crop productivities were evaluated in the north and south sun‐exposed faces of the plots during three cultivation cycles after thinning. In comparison with CFS, PAR transmittance in the ICLF systems decrease varied according to the time of day, period of the year, distance of the sampling position from the trees, the sun‐exposed area (north and south faces) and time after thinning. Soybean productivities in ICLFS were similar to those of CFS in the first and second crop cycles, but significantly lower (p < 0.05) in the third crop cycle. In the ICLFT system, soybean productivity was similar to that of CFS in the second crop cycle but significantly lower in the first and third crop cycles. With regard to the maize crop, productivities decreased in the order CSF > ICLFS > ICLFT in all cultivation cycles. Our results showed that PAR transmittance and soybean/maize productivities were positively influenced by thinning of eucalyptus stands, particularly in ICLFS system.
