This requires precise modelling of tree water demand under varying conditions. However, current methods often lack accuracy or require extensive data inputs. In this study, we adopted and evaluated a simple, mechanistic, low data-input transpiration model for macadamia trees. To this end, we conducted a comprehensive experimental study in the sub-humid Levubu region, South Africa, collecting tree sap velocity data from two macadamia cultivars, along with microclimate and soil water data over two seasons. First, the model was calibrated under non-limiting water conditions using data on tree-intercepted radiation, vapor pressure deficit (VPD), and canopy conductance to simulate potential tree transpiration (T_d), representing the upper limit of macadamia water use. Secondly, we further developed the model to simulate T_d for water deficit conditions by rescaling simulated potential T_d based on the observed fraction of transpirable soil water (FTSW). The performance of the calibrated model was validated against observed T_d from (spared) independent datasets for both cultivars.</div><div>Observed macadamia T_d showed pronounced seasonal variability (ranging from 0.6 mm d⁻¹ in winter to 1.3 mm d⁻¹ in summer), largely influenced by varying VPD and FTSW. The model captured the strong response of stomatal closure to increasing VPD, reflecting the conservative water use of macadamia trees. Model performance was satisfactory for both cultivars, and under both non-limiting and water deficit conditions, with lower relative error measures in the latter. This indicates that the improved model under water deficit is well-suited for accurately estimating macadamia T_d under heterogeneous environmental conditions, making it a valuable tool for optimizing irrigation practices and conserving water resources in macadamia orchards.</div></div>","PeriodicalId":21679,"journal":{"name":"Scientia Horticulturae","volume":"341 ","pages":"Article 113970"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Susceptibility of ‘B74’ to internal disorders in association with VHT and flesh mineral composition was investigated. Fruit were sourced from orchards across three climatic regions of Australia: Northern Territory (NT), Far-north Queensland (FNQ), and South-east Queensland (SEQ). They were assessed over two successive seasons for internal disorders associations with mesocarp mineral composition. Flesh browning (FB) and flesh cavity with white patches (FCWP) defects were observed. FCWP was present only in VHT fruit. FB was independent of VHT. Over the two seasons, the highest FB incidence was observed in NT fruit (20 %) and the highest FCWP in FNQ fruit (65 %). FB was not observed in fruit from SEQ in either season.

One potential approach is to harmlessly utilize these materials as substrates for soilless cultivation. Nevertheless, the effects on plant growth and the underlying mechanisms of using sewage adsorbent-recycling materials as soilless cultivation substrates remain unclear. Clarifying these aspects is crucial for assessing the feasibility of reusing adsorbent-recycling materials. This study conducted soilless cultivation experiments on narcissus using phosphorus-recycling ceramsite (PC) after adsorption treatment of phosphorus-containing sewage to investigate its impact on plant growth. The results indicated that compared to commercial ceramic granules and control experiments, PC significantly promoted the growth of narcissus. Specifically, the average leaf lengths of narcissus in PC cultivation were 1.77- and 1.40-fold longer than in the control and commercial ceramic granule treatments after 30 d, respectively. The effects and contributions of various hydroponic solution indicators were assessed through Mantel analysis, Spearman correlation analysis, and random forest algorithm. The findings confirmed that phosphorus content and pH in the hydroponic solution had a substantial impact on narcissus growth (<em>p</em> &lt; 0.01). Additionally, bioactive substances in the hydroponic solution were detected by three-dimensional fluorescence excitation-emission spectroscopy (3D-EEM) and LC-MS. In summary, the mechanisms by which PC promotes narcissus growth primarily include: environmental stress on roots was reduced by PC by providing essential mineral elements and phosphorus to the hydroponic solution while mitigating pH decline; the accumulation of autotoxic substances such as cinnamic acid and apoptosis-inducing substances like stachyose in the hydroponic solution is inhibited, while the production of growth-promoting substances is enhanced; microbial content in the hydroponic solution is reduced to minimize toxicity and competitive effects.

In this study, multiple bioinformatics tools were employed to identify 67 members of the <em>NRT1</em> gene family in dwarf coconuts, which can be categorized into 8 subfamilies. The analysis also determined the <em>NRT1</em> genes' molecular weight, chromosome distribution, subcellular localization, transmembrane structure, and conserved structural domains.

Transcriptome and qPCR analysis revealed that after 7 days of cold stress, the expression levels of the coconut <em>CnNRT1</em> genes generally decreased significantly. This suggests that cold stress may inhibit the absorption and transport of nitrate nitrogen in coconuts. In a combined examination of tall and dwarf coconut varieties, it was observed that <em>CnNRT1.5, CnNRT1.8, CnNRT1.13</em>, and <em>CnNRT1.17</em> genes responded promptly to cold stress signals after 8 h, showing heightened expression levels in various plant parts such as roots, stems, floral organs, and fruit peels.
