In this study, a randomized complete block design with 36 plants in Shiraz vineyard with simulated peeler, washing and control treatments was used to study the effect of microgravity on grape varieties. After applying the treatments, chlorophyll a and b, branch length, leaf relative water content, dry weight and leaf area as vegetative and biochemical traits, fruit formation, number of cubes per panicle, panicle weight, sugar percentage in cabbage and yield as traits Productivity of grapes was measured. Data analysis was done by analysis of variance and comparison of the meanings with Tukey test. The results showed that desert racecrine reduced the vegetative and reproductive traits of grapevine. Chlorophylls a and b were decreased 13.6% and 34.5%, respectively. Branch length and leaf relative water content did not change under threshing stress, but dry weight and leaf area decreased by 61.6% and 34.4%, respectively, and the difference between treatments was significant at 5% probability level. The leaves were washed out to eliminate the effect of the microtubules on plant growth and there was no difference between the treatment and the control. Formation of fruit is the most important phonological stage of garden trees, which is a significant reduction in insemination and formation of cabbage in grapevines. Reducing cabbage formation reduced the weight of the cluster and eventually decreased the yield by three times the plant yield and the difference was significant at the probability level with washing and control at 1% probability level. Washing the plant after spraying the thimble removed it from the leaves and the flowers opened the grapes and increased the yield of the plant, and with the control in one floor. The occurrence of reindeer phenomenon at pollination and inoculation stage can reduce fruit and yield formation.
