Summary: Salinity is a detrimental stress for crop productivity, but can be overcome by growing high value tree species on saline lands. This study evaluated the effect of saline irrigation and different host species on the growth, physiological processes, and salinity tolerance of sandalwood. Results showed that sandalwood grown with Dalbergia sissoo, Azadirachta indica, and Melia dubia exhibited higher growth and tolerance under salinity stress. The growth parameters of sandalwood were negatively correlated with Na+ ion under salinity stress. Hosts Melia dubia, Dalbergia sissoo, and Azadirachta indica showed minimal decline in sandalwood growth and biomass under salinity stress. This study highlights the importance of host species in modulating sandalwood growth and its potential for cultivation in degraded saline soils.

Summary: The natural populations of East Indian sandalwood (Santalum album L.) have greatly declined due to overexploitation in the past three decades. Santalum album L. seeds have poor germination, hindering nursery seedling production and plantation establishment. This study investigated the effects of hydro- and osmopriming on the germination and seedling performance of Santalum album L. The results showed that osmopriming with 5% PEG solutions for 2 days resulted in the highest germination (79%), which was 42% higher than the control. Longer priming times (6-8 days) had no effect or negatively affected germination and growth. Osmopriming can be recommended as a low-cost technology to enhance seed germination and seedling growth for quality planting material of Santalum album L.

Summary: Sandalwood is highly valued for its fragrant heartwood and oil extraction, with santalols being the main components synthesized via the MVA pathway. The isolation and identification of SaMK and SaPMK genes in S. album, their high homology with genes from other plants, and their functional complementation in yeast indicate their crucial role in MVA biosynthesis. SaMK and SaPMK are constitutively expressed in various tissues and upregulated by methyl jasmonate, providing insights for further research on santalol biosynthesis.

Summary: AREB/ABF/ABI5 transcription factors play a role in regulating ABA-related gene expression and enhancing plant adaptability to environmental stress. Through genome-wide analysis, 10 SaAREB genes were identified in sandalwood, which were divided into five subfamilies. SaAREB genes encode unstable hydrophilic proteins and are localized in the nucleus. SaAREB1 responds to prolonged drought and is highly expressed in stems, while SaAREB3, SaAREB7, and SaAREB8 specifically respond to ABA treatment. These findings lay the foundation for further understanding the role of ABRE/ABF/ABI5 genes in santalol formation in Santalum album L.

Summary: The shape of wheat seeds is a key factor affecting the accuracy of discrete element simulation. An ellipsoid modelling method is proposed to accurately simulate the movement of wheat seeds. The feasibility of ellipsoid modelling is verified by comparing the simulation and bench test results with the multi-sphere modelling resolutions. The results show that the ellipsoid model is more accurate and has a shorter calculation time, providing a new method for wheat seed simulation.

Summary: This study uses the discrete element method to investigate the impact of irregular maize on the performance of a high-filling-rate seed metering device. The results reveal that the disturbances caused by the three wheels in the seed box lead to the formation of large and small cycles of seed transport. Increasing the angular speed of the three wheels reduces the rate of seed filling in the seed filling regions due to gravity and disturbances. Additionally, the analysis shows that the angular speed of the taking seed wheel has an effect on the coefficient of variation of the seed drop location.

Summary: This paper investigates the energy absorbed by a Roll-Over Protective Structure (ROPS) cab during controlled lateral rollover testing on a modern narrow-track tractor. Tests with different wheel configurations show that narrow tires consistently subject the ROPS cab frame to more energy compared to wide tires. Further understanding of the influence of tire configurations and silent-blocks' dynamic performance on energy partitioning is warranted.

Summary: Access to interactive, simulated work environments through virtual reality (VR) has the potential to teach safety in design (SiD) to engineering students in a cost-effective and convenient manner. This study examined the use of VR simulation in engineering design units at an Australian university to enhance students' understanding of SiD. The findings suggest that VR simulation is an effective learning tool, but the combination of different learning elements is crucial for achieving desired learning outcomes.

Summary: The accuracy of predicted breeding values (PBV) for low heritability traits can be increased by utilizing information from correlated traits. A study compared the accuracy of PBV for 10 correlated traits in a genetically diverse field pea population using univariate or multivariate linear mixed model (MLMM) analysis. The MLMM approach improved the accuracy of PBV and showed potential for increasing genetic gains in early generation selection cycles.

Summary: This study evaluated seed retention of subterranean clover across different subspecies and found that peduncle tensile strength was greater than burr-to-peduncle attachment strength. As the plants senesced, both strength measurements decreased significantly, related to reductions in burr moisture content, and burr and peduncle diameters. These findings are important for commercial production and suggest the potential for harvesting seed before plant senescence with appropriate machinery, although further evaluation is needed for implications on seed viability and yield.

Summary: This study found that engineering educators can effectively utilize HMD VR simulations to teach students about safety in design. It was demonstrated that engineering students are able to identify safety hazards in HMD VR simulations whether they are operating the equipment or observing another student in their group. The findings suggest that one HMD VR set per student group is sufficient, making inclusive use of HMD VR simulations feasible even for students who are unwilling or unable to wear the headset.
