“…The dissection was carried out from the top of the bud down towards the growing point, exposing leaf primordia and inflorescence primordia (IP) (Dahal, Bhattarai, Walsh, Midmore, & Oag, 2022). In accordance dissecting microscope images of Dahal et al (2022), stages 4-5 were recognized. Primary buds with one or more inflorescence primordia were considered as fruitful buds and the quantity of inflorescence primordia within a primary bud served as the expression for the concept of bud fruitfulness (Dahal et al, 2022).…”

After budburst, the number of bunches from each bud/node/cane/vine were assessed to determine actual fruitfulness i.e., observed bunch number of the vine.…”

Bud dissection is generally done to determine potential bud fruitfulness (average number of potential inflorescence primordia), can be used to predict the next season’s crop yield and make decision on pruning by analyzing fruitfulness of bud with respect to its position on cane/spur in order to achieve desired crop load. Comparison of potential inflorescence primordia with actual bunches with respect to each node give reliability on data from bud-dissection. The objective of this study was to detect potential inflorescence primordia and correlate it with observed bunches in vine. Bud dissection was carried out in a spur (having 4 buds from basal node towards apex) per vine of var. Himrod and var. Steuben from a vineyard of Warm Temperate Horticulture Centre, Kirtipur, Kathmandu, Nepal with the help of micro-dissection tools under stereo-microscope. It was revealed that cultivars ‘Himrod’ and ‘Steuben’ were both more prolific toward the buds located on distal nodes in comparison to buds situated on basal nodes; as a result, it was found that bud dissection can be used as a decisive tool for the detection of bud fruitfulness, thus for yield prediction and to develop appropriate management practice.
