| dc.description.abstract | La cebolla es una especie hortícola que se produce por semillas y completa su ciclo en dos años. En condiciones normales, la floración se produce el segundo año de cultivo, cuando se hace la plantación de bulbos es una planta bianual que necesita que bajas temperaturas induzcan la diferenciación de las yemas florales para pasar de la fase vegetativa a la reproductiva y finalmente producir el cuajado de la semilla. El objetivo de esta investigación fue estudiar el proceso de producción de semilla sexual de bulbos vernalizados. Una vez finalizado el proceso de vernalizacion los bulbos fueron sembrado bajo las condiciones del campo experimental Las Cuibas del INIA Lara ubicado a 09º48’40’’ N y 69º32’35’’ W, con altitud de 1648 msnm, con temperaturas que oscilaron entre 22,15 ºC máx. y 14,95 ºC min, y precipitación de 1190,1mm.

| dc.description.abstract1 | Onion is a horticultural species that is produced by seeds and completes its cycle in two years. Under normal conditions, flowering occurs the second year of cultivation, when planting bulbs is a bi-annual plant that needs low temperatures to induce differentiation of flower buds to pass from the vegetative to the reproductive phase and finally produce the Seed curd. The objective of this research was to study the process of producing sexual seeds from vernalized bulbs. Once the vernalization process was completed, the bulbs were sown under the conditions of the INIA Las Cuibas experimental field, located at 09º48'40 '' N and 69º32'35 '' W, with an altitude of 1648 meters above sea level, with temperatures ranging from 22.15 ° C max. and 14.95 ° C min, and precipitation of 1190.1mm. Once the bulbs were sown and developed, the beginning of flowering was evaluated, which was counted from the beginning of planting, the number of umbels and flowers per umbel determined by counting in 300 randomly selected bulbs and in the seeds the number and weight of seeds by umbels. The beginning of flowering occurred 32 days after sowing, The average number of inflorescence of each sown bulb was two, The umbel type inflorescences produced between 200 and 250 white flowers and had on average a 3 seeds, They are mature at 90 days after sowing. Each umbel produced an average of 750 seeds weighing 1.36 g. The weight of 1000 seeds was 2.27 g. | es_VE |
