Waterlogging reduces shoot growth and bud fruitfulness in pot‐grown grapevines with a split‐root system

Waterlogging reduces shoot growth and bud fruitfulness in pot‐grown grapevines with a split‐root... Sultana grapevines (Vitis vinifera L. Sultana) with their root system split between two pots, a and b, were exposed to recurring cycles of waterlogging. Either none, half or the whole root system was waterlogged for the first 3 or 7 days of a 14 day irrigation cycle. Treatments were designated a0b0, a0b3, a3b3, a0b7, and a7b7, respectively where a and b refer to pots and subscripts refer to duration of waterlogging. For example, a0b3 indicates that pot a remained drained, whereas pot b was waterlogged for the first 3 days in a 14 day cycle; a7b7 indicates that both pots a and b were waterlogged for the first 7 days of a 14 day cycle. All material (shoots plus split roots) was harvested after 9 cycles for examination of bud anatomy and dry mass measurement. Waterlogging reduced shoot dry mass from 120 g per vine in control vines (a0b0 not waterlogged) to 90 g in a0b3, 67 g in a3b3, 72 g in a0b7 and 20 g in a7b7. Where entire root zones were waterlogged, root dry mass fell from 43 g per vine in a0b0 to 35 g in a3b3 and 17 g in a7b7. By contrast, waterlogging half the root zone had no effect on total root mass. Root mass was 45 g in a0b3 and 48 g in a0b7. Waterlogging caused the shoot:root ratio to fall from 2.8 in a0b0 to 1.1 in a7b7. Partial waterlogging caused a redistribution of root mass between pots a and b. Waterlogging of roots in pot b increased the mass of roots in the drained pot a. The mass of roots in pot a of a0b0 was 21.8 g, a0b3 30.1 g and a0b7 41.7 g. Buds between nodes 1 and 12 on harvested shoots were scored for fruiting primordia.

Abstract

Sultana grapevines (Vitis vinifera L. Sultana) with their root system split between two pots, a and b, were exposed to recurring cycles of waterlogging. Either none, half or the whole root system was waterlogged for the first 3 or 7 days of a 14 day irrigation cycle. Treatments were designated a0b0, a0b3, a3b3, a0b7, and a7b7, respectively where a and b refer to pots and subscripts refer to duration of waterlogging. For example, a0b3 indicates that pot a remained drained, whereas pot b was waterlogged for the first 3 days in a 14 day cycle; a7b7 indicates that both pots a and b were waterlogged for the first 7 days of a 14 day cycle. All material (shoots plus split roots) was harvested after 9 cycles for examination of bud anatomy and dry mass measurement. Waterlogging reduced shoot dry mass from 120 g per vine in control vines (a0b0 not waterlogged) to 90 g in a0b3, 67 g in a3b3, 72 g in a0b7 and 20 g in a7b7. Where entire root zones were waterlogged, root dry mass fell from 43 g per vine in a0b0 to 35 g in a3b3 and 17 g in a7b7. By contrast, waterlogging half the root zone had no effect on total root mass. Root mass was 45 g in a0b3 and 48 g in a0b7. Waterlogging caused the shoot:root ratio to fall from 2.8 in a0b0 to 1.1 in a7b7. Partial waterlogging caused a redistribution of root mass between pots a and b. Waterlogging of roots in pot b increased the mass of roots in the drained pot a. The mass of roots in pot a of a0b0 was 21.8 g, a0b3 30.1 g and a0b7 41.7 g. Buds between nodes 1 and 12 on harvested shoots were scored for fruiting primordia. Fruitful primordia decreased from 6 out of 12 in a0b0 to 5 in a0b3, 3 in a3b3 and a0b7, and only 1 out of 12 in a7b7.
