A functional association in Vitis vinifera L. cv. Cabernet Sauvignon between the extent of primary branching and the number of flowers formed per inflorescence
نویسنده
چکیده
• As we know, the inflorescences that will produce any year’s grape crop start differentiating inside the buds in the previous year. There are 2 main stages of development: formation of primary branches starts in Year 1, before the vine goes dormant; secondary and tertiary branching, as well as individual flower differentiation, continues around budbreak of Year 2. Thus, the cropping potential in Year 2 is set rather early during shoot formation in Year 1.

The bouquet of grapevine (Vitis vinifera L. cv. Cabernet Sauvignon) flowers arises from the biosynthesis of sesquiterpene volatiles in pollen grains.
Terpenoid volatiles are important information molecules that enable pollinators to locate flowers and may protect reproductive tissues against pathogens or herbivores. Inflorescences of grapevine (Vitis vinifera L.) are composed of tiny green flowers that produce an abundance of sesquiterpenoid volatiles. We demonstrate that male flower parts of grapevines are responsible for sesquiterpenoid fl...

متن کاملProteomic analysis reveals differences between Vitis vinifera L. cv. Chardonnay and cv. Cabernet Sauvignon and their responses to water deficit and salinity.
The impact of water deficit and salt stress on two important wine grape cultivars, Chardonnay and Cabernet Sauvignon, was investigated. Plants were exposed to increasing salinity and water deficit stress over a 16 d time period. Measurements of stem water potentials, and shoot and leaf lengths indicated that Chardonnay was more tolerant to these stresses than Cabernet Sauvignon. Shoot tips were...
متن کاملDevelopment of inflorescence primordia in Vitis vinifera L cv. Chardonnay from hot and cool climates
• Flower formation in grapevines follows 3 steps: 1) formation of uncommitted primordia, also called anlagen, within the latent buds; 2) differentiation of uncommitted primordia into inflorescence primordia; and 3) differentiation of inflorescence primordia into individual flowers . Steps 1 and 2 happen during the previous season, whereas Step 3 does not happen until budbreak of the current sea...
متن کاملPhenolic profiles and antioxidant properties of young wines made from Yan73 (Vitis vinifera L.) and Cabernet Sauvignon (Vitis vinifera L.) grapes treated by 24-epibrassinolide.
The grape berries of two varieties, Yan73 (Vitis vinifera L.) and Cabernet Sauvignon (CS) (Vitis vinifera L.) were treated with 0.40 mg/L 24-epibrassinolide (EBR), 1.00 mg/L brassinazole (Brz), and deionized water (control), at the veraison period. The EBR treatment significantly increased total phenolic content (TPC), total tannin content (TTC) and total anthocyanin content (TAC) of Yan73 and ...
