This invention relates to the field of bioengineering technology and provides an application of the maize heat shock transcription factor gene ZmHSF18, wherein the nucleotide sequence of the maize heat shock transcription factor gene ZmHSF18 is shown in SEQ ID NO:1. Experiments have demonstrated that overexpression of the maize heat shock transcription factor gene ZmHSF18 in plants can significantly improve seed germination rate and frozen survival rate at the mature stage under low-temperature stress, reduce malondialdehyde accumulation, and increase superoxide dismutase activity. Therefore, this maize heat shock transcription factor gene ZmHSF18 can be used to improve plant cold tolerance and create transgenic plants with enhanced cold tolerance, possessing important application value in plant genetic engineering and stress resistance breeding.

The present application belongs to the technical field of plant morphology, and particularly relates to a seed plant propagule three-dimensional shape measurement method based on a video stereomicroscope, comprising: collecting seed plant propagules at the mature stage and air-drying to a constant weight; classifying the propagules according to the seed, fruit shape and surface accessory structure, and determining the measurement criteria of the shape of different categories of propagules; scanning the three-dimensional structure of each category of propagule by using a video stereomicroscope, and accurately measuring the shape parameters length, width and thickness of the propagule; normalizing each category of propagule, calculating the shape index of the propagule, and representing the closeness to a spherical shape. The method quantifies the complex three-dimensional shape characteristics of the seed plant propagule into a comprehensive shape index, realizes accurate quantitative measurement and digitization of the morphological characteristics of the propagule, solves the pain point of determining the shape of the propagule by using a traditional observation tool, and facilitates the comparative identification of the three-dimensional shapes of different categories of seed plant propagules.

This utility model belongs to the field of passion fruit technology, and in particular to a climbing device for passion fruit cultivation. It includes an adjustable climbing structure with outward-expanding climbing structures on both the front and rear sides, and reinforced support structures on both sides. Through the adjustable climbing structure and the reinforced support structures, the reinforced support structures effectively support the adjustable climbing structure, ensuring its stability. Furthermore, the device possesses high flexibility and adaptability, allowing for precise adjustments based on the actual needs of passion fruit at different growth stages. Whether it's the initial climbing during the seedling stage or the vigorous growth during the mature stage, this structure provides just the right amount of support and guidance, not only helping the vines achieve even distribution throughout the growth process but also effectively preventing insufficient light caused by overly dense vines.

This utility model discloses an integrated device for plant seedling maintenance, relating to the field of seedling maintenance technology. It includes a support frame, of which multiple supports are provided, and a ring-shaped support member is fixedly connected to the top of each support frame. A ring-shaped irrigation member is slidably connected to the center of the bottom of the ring-shaped support member. When it is necessary to adaptively adjust the irrigation height of the irrigation nozzle, the positioning pin on the outer wall of the sliding plate can be pulled outwards, separating its end from the positioning hole. After being pulled out, the ring-shaped irrigation member can be slid up and down along the guide groove and slide of the support frame according to actual needs until the irrigation nozzle is aligned with the target irrigation area. Then, the positioning pin is released, allowing it to be inserted into the positioning hole of the corresponding height under the action of a compression spring, quickly locking the height of the ring-shaped irrigation member. The irrigation height can be adjusted according to the root distribution characteristics of the seedling and mature stages of the plant.

The present application relates to the beer brewing technical field, specifically to a kind of beer fermentation equipment and process, equipment includes yeast activation tank, main fermentation tank, flavour modification tank and post-mature wine storage tank in turn, respectively corresponding yeast activation, main fermentation, flavour modification, low-temperature post-mature four fermentation stages, quantitative sterile conveying pump and sterile control valve are achieved between each tank body quantitative sterile conveying of material, and each stage can be independently regulated and controlled environmental parameter;Process includes yeast activation stage, main fermentation stage, flavour modification stage and low-temperature post-mature stage.In the present application, each tank body only bears single fermentation function, single-tank failure does not affect the operation of other processes, realizes the accurate control of yeast metabolic pathway, directional enrichment of flavouring material, the consistency deviation of batch flavour is small, and beer flavour level is more rich, which can be widely applied to the large-scale production of various types of beer, especially suitable for customized production of high-quality craft beer.
