Abstract:
'Williams' is the most cultivated pear in Uruguay and requires more than 900 chill hours to exit from the endodormancy. When this condition is not satisfied, the application of budbreak promoters is necessary to facilitate the bud swelling. The experiments were carried out in a pear orchard of 'Williams' (Pyrus communis L.) located in the Experimental Station INIA Las Brujas, during the 2017-2018 season. The objective of the study was to evaluate the effect of budbreak promoter applications on budbreak. Two experiments were performed: Experiment 1 consisted in the application of Erger® 4%, Erger® 2% and mineral oil 4%, in two dates: August 15, 2017 and September 1, 2017. Experiment 2 consisted in the application of Erger® 8% and hydrogen cyanamide 1% on August 15, 2017 and Erger® 4% on September 28, 2017. In 2017 chill units in Uruguay were 187, while the average for the last 20 years is 843. Thus chill requirements of 'Williams' pears were not met. Because of the inadequate chill accumulation (32% of the chill units NDASH CU or 78% of the total chill portions NDASH CP), no difference was observed in the final budbreak among the treatments, and the budbreak percentage never exceeded 20% for any treatment. Analyzing the budbreak discriminated per type of shoot (vegetative spurs, reproductive spurs and one-year shoots), no significant differences were observed among the treatments except for vegetative buds in experiment 1, where the treatments with mineral oil achieved a higher final budbreak (20%).

Abstract:
BACKGROUND: The effects of growth stage (GS) and ensiling were assessed on whole-crop oat's (Avena sativa L. cv. Cantara) chemical composition, silage fermentation quality and in situ ruminal degradability. Oat was harvested and ensiled at six GS: boot, heading, water ripe, early milk, early dough and grain ripe (144, 151, 178, 234, 362 and 512 g kg-1 of dry matter (DM) of whole-crop forage, respectively). RESULTS: GS influenced chemical composition, silage fermentation quality and ruminal degradability of whole-crop oat. Lower DM and higher water-soluble carbohydrates (WSC) contents lead to adequate forage compaction and fermentation at early GS; however, effluent was produced until the dough stage (L and Q; P ? 0.003). Advancing in maturity increased (P < 0.001) crop yield (4.5 to 9.4 t DM ha-1), DM (144 to 512 g kg-1), neutral detergent fibre (NDF; 537 to 571 g kg-1 DM), lignin (44.6 to 71.3 g kg-1 DM) and starch contents (26.4 to 201 g kg-1 DM), and reduced (P < 0.001) crude protein (107 to 60 g kg-1 DM) and WSC (115 to 17.5 g kg-1 DM). DM and NDF ruminal degradability declined with maturity for fresh and ensiled forages (L and Q; P < 0.05). Density and buffering capacity decreased with GS (L and Q; P < 0.001), whereas pH and soluble protein increased (L and Q; P ? 0.004). CONCLUSION: The growth stage of oat influenced the nutritive value and ruminal degradation to a greater extent than ensiling, and thus it can play a paramount role in whole-crop oat silage quality. © 2021 Society of Chemical Industry. © 2021 Society of Chemical Industry.
