Water partitioning and respiration activity of dormant grape buds. By. The total water and the\ud intracellular fraction increased during the ecodormant period.\ud A method to evaluate bud water status by proton-nuclear magnetic\ud resonance was developed. Grape buds present anisotropic behavior. Using this\ud method, water content was. Shown is a schematic depicting the reciprocal grafts used to determine the in fl uence of the dormant bud at the cane internode on adventitious root formation by a recalcitrant to root and non. A grape-bud-oriented genomic platform was produced for a large-scale comparative analysis of bud responses to two stimuli of grape-bud dormancy release, .   Changes in main biochemical respiratory pathways in dormant nectarine floral buds were studied with nectarine trees (Prunus persica var. nectariana cv. Shuguang) in order to determine the function of respiration in dormancy release. Oxygen-electrode system and respiratory inhibitors were used to measure total respiratory rates and rates of respiratory pathways.

This occurred from November 24 to January Bud respiration rate showed a similar pattern, increasing from to nmoles CO 2 s −1 mg −1 dw, and bud water content increased from to mg mg −1 dw. In a day period after spraying, treated vines reached 50% budbreak, while controls reached only 7%. emphasized throughout this book. and the dormant bud. forms in the bract axil of the lateral bud. Because of. dormant grape. bud in leaf axil, showing primary. The roots form the plant–soil interface, while the trunk, cordons, and shoots of a vine form its stem. The shoots carry the leaves, buds, tendrils, and clusters. Leaves are arranged in spiral phyllotaxy in juvenile vines and in alternate phyllotaxy in mature vines. Buds are young, compressed shoots embedded in . This occurred from November 24 to January Bud respiration rate showed a similar pattern, increasing from to nmolesCO2s−1mg−1dw, and bud water .

Water Management for Grapevines Bill Peacock* The water requirement (evapotranspiration) of a mature vineyard varies from 22 to 28 inches, depending on the size of the leaf canopy. In addition to evapotranspiration, 6 to 8 inches of water may be needed some years for beneficial purposes such as leaching salts and providing frost protection. Temperature coefficient of respiration (Q 10) of forced primary grape buds at four developmental stages and four temperature intervals: 10 to 20C (A), 20 to 30C (B), 30 to 40C (C), and 40 to 50C (D).   'Pinot Noir' grape primary buds have a water/dry weight ratio of about 50% during the winter (Gardea et al., a) when they are endodormant, and in the early ecodormant stage. However, bud water content increases to 85% during the late ecodormant pe- riod, when buds .   Because the increase in the content of ABA and starch matched throughout the cycle of natural dormancy in grapevine buds, we decided to evaluate whether ABA promotes the synthesis of starch in grapevine buds. To this end, single-bud cuttings of dormant grapevine buds were sprayed with a μM ABA solution and water was used as the control.
