- Phenology of Flowering and Starch Accumulation in Grape (Vitis vinifera L.) Cuttings and Vines

....................................................................................................

TABLE 1. Number of flowers, berries per bunch, seeds per berries, and fruit set in ‘Gewurztraminer’ (GW) and ‘Pinot Noir’ (PN) grapes

For each stage, ten flowers from five inflorescences were used, each inflorescence sampling from a different vine or cutting.

Values are means of ten inflorescences ± s.e.

Statistical analyses were carried out using Student's t-test. Means for a considered parameter were not significantly different when followed by the same letter (P 0·05).

TABLE 2. Reproductive stages according to the classification of Eichhorn and Lorenz (1977)

A, Archeospore; SC, sporogenous cells; m, microspores; mMC, microspore mother cell; MMC, macrospore mother cell; Vm, vacuolated microspores; MPG, mature pollen grain; ESMC, embryo sac mother cell; ES, embryo sac; ST, sporogenous tissue; T, tetrads; YES, young embryo sac; YPG, young pollen grain.

For vine and cutting, data are the means of ten flowers from five different inflorescences, and each inflorescence was sampled from a different vine or cutting. For each stage of development, the ten flowers considered show similar results.

TABLE 3. Presence (+) or absence (0) of starch in Gewurztraminer (GW) and Pinot Noir (PN) vines and cuttings

For vine and cutting, ten flowers from five different inflorescences were analysed to study the presence of starch, and each inflorescence was sampled from a different vine or cutting. For each stage of development, the ten flowers considered show similar results for starch content. Structures are scored a ‘+’ if the ten inflorescences had starch, and a ‘0’ if the ten inflorescences had no starch.
