Occurrence and duration of phenological phases of Freesia x hybrida grown at different planting dates
Freesia (Freesia x hybrida) is one of the most cultivated species of cut flowers, ranking sixth in the international market. Pheno- logical processes occurring during the crop cycle are controlled by endogenous mechanisms and the environment, which in turn influence the duration and occurrence of th...

| description | Freesia (Freesia x hybrida) is one of the most cultivated species of cut flowers, ranking sixth in the international market. Pheno- logical processes occurring during the crop cycle are controlled by endogenous mechanisms and the environment, which in turn influence the duration and occurrence of the development phases. This study aimed to analyze the effect of planting dates (Feb 15, March 19, April 16, May 21, and June 21, 2021) on the occurrence and duration of the development phases of two freesia varieties (Blue Bayou and Yvonne). The trial was conducted in a high tunnel. The crop cycle was divided into vegetative, reproductive, and senescence phases. The number of leaves was counted daily. The development phases were significantly shortened with the delay of planting. The vegetative phase ranged between 2269.78 ± 19.22 and 736.50 ± 19.22 GDD for Blue B., and between 1864.48 ± 19.22 and 667.09 ± 19.22 GDD for Yvonne. The reproductive phase lasted 459.50 ± 20.99 and 379.51 ± 20.99 GDD for Blue B., 461.43 ± 20.99 and 487.29 ± 20.99 GDD for Yvonne. The senescence phase was shortened with delayed planting dates only for Yvonne. Plants cultivated at later dates (May 21, and June 21), and consequently exposed to increased photoperiod, had a lower number of leaves at flowering (7.85 ± 0.10) and were less exposed to inductive temperatures than plants cultivated earlier. The transition to the reproductive phase was determined by the interaction between photoperiod, temperature and plant age. |

Freesia (Freesia x hybrida) é uma das espécies de flores de corte mais cultivadas, ocupando o sexto lugar no mercado internacional. Os processos fenológicos que ocorrem durante o ciclo de desenvolvimento são controlados por mecanismos endógenos e pelo ambiente, que por sua vez influenciam a duração e ocorrência das fases de desenvolvimento. Este estudo teve como objetivo analisar o efeito das datas de plantio (15 de Fevereiro, 19 de Março, 16 de Abril, 21 de Maio, e 21 de Junho, 2021) na ocorrência e duração das fases de desenvolvimento de duas variedades de freesia (Blue Bayou e Yvonne). O ensaio foi conduzido em um túnel alto. O ciclo de cultivo foi dividido em fases vegetativas, reprodutivas, e de senescência. O número de folhas foi contabilizado diariamente. As fases de desenvolvimento foram significativamente encurtadas com o atraso da data de plantio. A fase vegetativa variou entre 2269,78 ± 19,22 e 736,50 ± 19,22 GD para a variedade Blue B., e entre 1864,48 ± 19,22 e 667,09 ± 19,22 GD para a Yvonne. A fase reprodutiva durou entre 459,50 ± 20,99 e 379,51 ± 20,99 GD para a Blue B. e 461,43 ± 20,99 e 487,29 ± 20,99 GD para aYvonne. A fase de senescência foi encurtada com datas de plantio atrasadas apenas para a Yvonne. As plantas cultivadas em datas posteriores (21 de Maio, e 21 de Junho), e consequentemente expostas ao aumento do fotoperíodo, apresentaram um menor número de folhas na floração (7,85 ± 0,10) e estavam menos expostas a temperaturas indutivas do que as plantas cultivadas mais cedo. A transição para a fase reprodutiva foi determinada pela interação entre o fotoperíodo, a temperatura e a idade das plantas. EEA Famaillá Fil: Santilli, Melisa. Universidad Nacional de Tucumán.
