Summary: This study aimed to improve the resistance of oil camellia anthracnose by crossing Camellia yuhsienensis with Camellia oleifera. However, unilateral cross-incompatibility (UCI) was found between C. oleifera and C. yuhsienensis during the breeding process. Five C. oleifera cultivars and four C. yuhsienensis materials were tested to confirm the UCI. The study provides important insights into interspecific hybridization and reproductive isolation mechanisms between C. oleifera and C. yuhsienensis.

Summary: This study analyzed the floral scent components of Lagerstroemia fauriei, L. 'Tuscarora', and their fragrant hybrids using headspace solid-phase microextraction and gas chromatography-mass spectrometry. The results showed significant differences in the numbers and types of volatile compounds among the taxa. The hybrids' fragrances were found to be more similar to L. 'Tuscarora'. This research provides a foundation for understanding the genetic rules of Lagerstroemia floral scent components and guiding its fragrant germplasm breeding.

Summary: Cross-pollination in the cannabis industry has been a topic of concern, with fears that low THC hemp may become high in THC if pollinated by high THC cannabis. However, the article highlights that there are multiple factors that contribute to THC levels, debunking the misconception that cross-pollination alone leads to increased THC in hemp crops.

Summary: This study assessed the cross-compatibility of yam and analyzed the factors influencing pollination success to improve hybridization practices in yam breeding. The results showed that interspecific crossing combinations had lower crossability rates and seed production efficiency compared to intraspecific combinations. Weather conditions and pollinator's skills were the main contributors to the low success rate in intraspecific crosses, while genetic distance and heterozygosity played a minor role. The study also found that interspecific barriers were both pre-zygotic and post-zygotic, resulting from evolutionary divergence among yam species.

Summary: In this study, three L. indica cultivars with diverse flower traits were used to make crosses with L. caudata. A total of 2832 crosses were obtained, of which nearly 260 hybrid seedlings survived. The hybrids showed intermediate traits in comparison to their parents, but varied in terms of leaf and flower characteristics, including fragrance. These findings suggest that the floral fragrance of Lagerstroemia cultivars can be optimized through the use of L. caudata and the hybrids obtained in this study, providing a basis for the development of superior plants with unique ornamental traits.

Summary: Casuarina species are widely planted in the tropics for wood production and environmental services. Breeding programs are currently focused on producing interspecific hybrids with forestry characteristics. This study investigated the floral characters and their effect on pollen and seed output in three Casuarina species. The results showed that storing pollen at low temperatures improved viability, and conducting hand pollination during the peak receptivity period increased hybridization success.

Summary: This study found that the viability and germination rate of fresh pollen varied under different storage temperatures, with Budimka cultivar showing the highest viability and germination rate. Storage at 4 degrees Celsius extended the pollen viability and germinability, while -20 or -80 degrees Celsius significantly prolonged the pollen longevity for all cultivars. After 6 months, pollen stored at -20 and -80 degrees Celsius had much higher germination rates compared to pollen stored at room temperature for the same period.

Summary: The present study investigated pollen morphology and viability of four Ocimum L. species, revealing that O. basilicum had the highest pollen viability and germination rate, while O. sanctum had the lowest viability. The highest pollen germinability for all four Ocimum species was observed at -20 degrees Celsius. This research could aid in taxonomic identification of Ocimum species and be utilized in conservation efforts and improvement through cross-hybridization breeding programs.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: This study revealed that nitrogen deficiency can lead to increased production of reactive oxygen species (ROS) and methylglyoxal (MG), but also enhances the ability of leaves and roots to detoxify these molecules. The effects of nitrogen deficiency on ROS and MG generation and their detoxification systems were found to be different in leaves and roots, with roots being more affected.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: This study used Sentinel-2 satellite images to estimate biophysical and biochemical parameters of spinach crops and found that canopy-level parameters were estimated more accurately. The estimation of the canopy-scale parameter AGB using MCARI showed the highest accuracy, while the estimation of the leaf-scale parameter LCC using NDWI showed the lowest accuracy. At the field scale, the validation results for AGB estimation using SR were the best.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
