“…It is reliably known that just one glass of watermelon juice is quite enough to satisfy the daily need of a healthy person for such a vital trace element as magnesium [41]. Due to this property, nutritionists strongly recommend including watermelon juice in the diet of people with arterial hypertension [42].…”

The objects of the research are fruit and berry juices from watermelon, rosehip, apples and pumpkin. The influence of the physico-chemical parameters of fruit and berry juices on the process of storage and blending is investigated. It has been found that quantitative regulation depending on the physico-chemical parameters of fruit and berry juices during the development of blended juice technology makes it possible to develop a drink with a long shelf life. The developed juices should satisfy the body's needs for vitamins and minerals in food necessary for the normal development of the body. Based on research, watermelon-pumpkin-rosehip juice is recommended. However, the consumer properties of natural juices depend on the variety and climatic conditions of growth. The climatic conditions of growth and the variety significantly affect the physico-chemical parameters of the juices obtained from them. All this allows us to assert that it is advisable to conduct a study devoted to establishing the influence of the physico-chemical parameters of fruit and berry juices based on watermelon juice on the process of storage and blending. Juices are the most technologically advanced product for creating new types of functional nutrition. In addition, they contain a complex of vitamins and minerals in their composition. In connection with the above, the development of technology and the organization of the production of functional purpose juices are the solution to problems related to nutrition. It is found that the resulting new product – watermelon-pumpkin-rosehip drink will allow you to get a new product with high quality indicators and expand the range of fruit and berry drinks based on watermelon juice

“…Before removing the rootstock growth point, the rootstock needs to be held using the inclined insertion grafting method. A rootstock seedling clamping mechanism was designed in our previous study [23], as shown in Figure 1. The clamping mechanism mainly involves clamping blocks, silicone rubbers, and cylinders.…”

Rootstock has a soft tissue that should be held carefully to avoid mechanical damage. Holding the rootstock stem is a significant factor in the grafting process, with direct consequences on the survival rate of grafting. To analyze the damage mechanism of clamping rootstock, a finite element model of the clamping mechanism was established, and different clamping velocities and silicone rubber thicknesses were then studied in this study using the finite element method (FEM). The density and elasticity modulus of the rootstock stem and silicone rubber were determined experimentally using standard methods. The results show that as the clamping velocity increased, the contact force on the rootstock stem increased, and the clamping velocity should be lower than the critical velocity to reduce the probability of damage occurrence on the stem. The increase in silicone rubber thickness would decrease the force on the stem, while also resulting in the instability of the rootstock clamping. A silicone rubber thickness of 4 mm was confirmed as an appropriate thickness for this device. The simulation results were compared with the experimental results, and the mean error was 7.01% within the allowable range, which indicated that the FEM simulation model was reliable.

“…In the previous study, a rootstock clamping mechanism was designed and tested. The test results showed that the mechanism had a better holding effect on rootstocks, with low damage [20]. To evaluate the rootstock deformation during the holding process, further studies need to be conducted on the viscoelastic properties of rootstock.…”

The fragile structure of a rootstock predisposes the stem to mechanical damage during grafting. Thus, it is necessary to take into account the rootstock’s rheological properties under mechanical compression when designing a clamping mechanism. This study focused on cucurbit, a typical rootstock for watermelon grafting. Firstly, we adopted a four-element Burgers model to analyze viscoelastic behavior and deformation characteristics of the rootstock, then conducted creep tests to obtain the parameters of the viscoelastic model. Next, we developed a model for the rootstock during holding based on viscoelastic parameters, loading force and contact time. Moreover, we evaluated the effect of various loading forces and test velocities on creep deformation to reveal the least damage on the rootstock. Results showed that the influence of loading force on the creep deformation was greater than test velocity. Finally, the holding test indicated that the clamping mechanism with silicone rubber can effectively prevent the damage to the stem. Specifically, the loading force should be controlled below 4 N to reduce the associated damage. Taken together, our findings provide a theoretical basis for analyzing the holding damage mechanism during watermelon grafting.
