ABSTRACT.
Onion sets (small onion bulblets) may allow seed production with lower costs than the traditional biennial cycle. This research aimed to evaluate the seed-set-seed method for seed production of three onion cultivars grown in Uruguay. Small (16-21 mm) and large (26-31 mm) onion sets were evaluated in combination with four storage periods at 7°C (0, 15, 30 and 45 days) for the cultivars INIA Casera (IC) and Pantanoso del Sauce CRS (PS), and 0 and 30 days for INIA Valenciana (IV). Large sets produced higher yield for IC (1001 kg ha-1) and PS (745 kg ha-1) than small sets, with no influence of the cold period. Large set-size in combination with 30 days storage at 7°C showed the highest yield for IV (595 kg ha-1). Seed weight was only influenced in IC, with higher values for no cold storage and small sets with 30 days cold-storage. Germination in IV was higher for large sets with 30 days at 7°C, whereas in PS germination was higher for large sets with 15 days at 7°C. All treatment combinations showed germination higher than the 75% required in certification rules. Results suggest the viability of this method to obtain high quality seeds. |

ABSTRACT
This study evaluated the effect of shearing ewes at 50 day of gestation on the growth, reproductive behavior and response to a gastrointestinal parasite challenge in the
female offspring from weaning (104 d) to 18 months old. Fifty-seven Polwarth female lambs were used, 22 single (S) and 35 twin (T) born to ewes either shorn at 50 days of pregnancy (PS, n = 23) or shorn at 62 days post-partum (U, control, n = 34) resulting in four sub-groups: SPS: single female lambs born to ewes shorn at 50 days of pregnancy (n = 8), SU: single female lambs born to ewes shorn postpartum (n = 14), TPS: twin females lambs born to ewes shorn at 50 days of pregnancy (n = 15) or TU: twin female lambs born to ewes shorn postpartum (n = 20). All progeny was managed together under improved pasture with a minimum forage allowance of 6% live weight on dry matter basis. Body weight, body condition score (BCS) and fecal eggs count was recorded every 14 d from weaning to 18 months of
age. Concentrations of progesterone were measured weekly (from 4 to 10 months of age and from 14 to 18 months of age) to establish the onset of puberty. Ovulation rate (545 ± 1.0 d old) was recorded. Prepartum shearing did not affect the age at puberty or the ovulation rate, but those female lambs born as singles were more precocious (P = 0.03) and heavier (P = 0.02) at puberty than twin born female lambs. Both the average value of parasite egg count (P = 0.07) and the Famacha index (P = 0.02) for the entire study period were lower in female lambs born to prepartum shorn ewes than those born to postpartum shorn ewes. In conclusion, shearing at 50 days of gestation did not affect the growth or the reproductive behavior of female offspring. However, female lambs born from ewe shorn during gestation showed a better response to the parasite challenge, but further research is required to confirm this. MenosABSTRACT
