Abstract

Grapevine (Vitis vinifera) is one of the most widely cultivated horticultural plants with high socioeconomic value, and itis extensively appreciated for its colorful berries and the wines made from its berries. Variations in the phytochemical compoundsof different tissues of grape berries under different cultural practices have been explored in numerous studies in recent years. In thisstudy, variations in the physical, proximate, and fatty acid compositions of grape (Vitis vinifera L. ‘Red Globe’) seeds under differentpartial root-zone drying and deficit irrigation treatments were investigated. The results showed that different irrigation treatments andirrigation levels affected the vitality, moisture, and oil contents of grape seeds. However, the number of fatty acids in grape seed oil didnot change according to the different irrigation treatments. The major fatty acid in grape seed oil for all irrigation treatments was linoleicacid, followed by oleic acid, palmitic acid, and stearic acid, respectively. Under drought stress, the linoleic acid in the seeds of the grapesdecreased while the oleic, palmitic, stearic, myristic, docosahexaenoic, and palmitoleic acids increased. The partial root-zone dryingtreatments increased the amount of polyunsaturated fatty acids (PUFAs) and the ratio of PUFAs to saturated fatty acids in the seeds.
