Resumo Plantas ornamentais, como gladíolos, são uma boa opção para produtores com área limitada, pois são altamente rentáveis e possuem menor custo de produção. O experimento foi conduzido com o objetivo de estudar a influência da aplicação exógena do ácido giberélico nas características vegetativas e reprodutivas de gladíolos, em condições subtropicais. O delineamento experimental foi em blocos casualizados com dois fatores: cultivares (White Prosperity e Red Advance) e ácido giberélico (GA3) (0, 50, 100, 150, 200 mg L-1), com três repetições. Os resultados mostram que a maioria dos parâmetros foi significativamente influenciada pelo ácido giberélico. Maior porcentagem de brotação, número de folhas e cormos planta-1, bem como menor número de dias para brotação, surgimento da espiga e abertura floral foram registrados nas plantas tratadas com 200 mg L-1 de ácido giberélico (GA3). A cultivar Red Advance, além de menor número de dias para surgimento da espiga e a abertura da flor, apresentou maior número de folhas por planta e maior diâmetro e peso dos cormos. Conclui-se, com base nos resultados, que o tratamento de cormos com 200 mg L-1 de ácido giberélico pode incrementar mais o crescimento e o rendimento da cultivar de gladíolo Red Advance do que da White Prosperity nas condições de região subtropical.

Abstract Ornamental plants like gladiolus are suitable option for growers with lower amount of land, as they are highly economic and have lower cost of production. An experiment was conducted with aim to study the exogenous application influence of gibberellic acid on vegetative and reproductive characteristics of gladiolus was conducted under the subtropical conditions. The experiment was laid out in two factors randomized complete block design and replicated three times. Gibberellic acid (GA3) was used in different concentrations (0, 50, 100, 150, 200 mg L-1) to corms of two cultivars of gladiolus (‘White Prosperity’ and ‘Red Advance’). Results showed that most of the parameters were significantly influenced by gibberellic acid at 200 mg L-1. The maximum sprouting, number of leaves plant-1, daughter corms per plant, less number of days to corm sprouting, days to spike emergence and flower opening were recorded in plants treated with 200 mg L-1 gibberellic acid (GA3). ‘Red Advance’ produced more number of leaves plant-1, corm diameter, corm weight, and less number of days to spike emergence and flower opening. It can be concluded from the present findings that the treatment of corms with 200 mg L-1 gibberellic acid can improve the growth and yield of cultivar Red Advance than White prosperity under the subtropical conditions.

ABSTRACT This study was designed to evaluate the effects of adding kefir on body measurements, giblet weight, and gut morphological patterns of geese through drinking water. A total of 54 birds were divided into three groups, each comprising 18 birds, and each group was further divided into three subgroups containing six birds each. One group served as the control group, while the other two groups were given kefir-treated drinking water at the ratios of 2.5 and 7.5%, respectively. No significant effects of kefir supplementation on body measurements, spleen weight, bursa weight, and gut morphology were observed. It is concluded that kefir may be used in poultry feed with an inclusion rate of 7.5% without imposing any adverse effect on the measurements of body structures, weights of visceral organs, and gut morphology.

ABSTRACT The present study examined the effect of supplementing the diets of laying hens with Pistacia terebinthus seed meal on egg quality during different storage intervals. A total of 192 laying hens (Babcock) were divided into six groups, and each group was further divided into four subgroups with eight hens each. Pistacia terebinthus seed meal was added to the diets of laying hens in the experimental groups at a rate of 0, 10, 20, 30, 40, and 50 g kg−1 of feed. At the end of the study (56 days), a total of 288 eggs (48 eggs from each group) were collected randomly. Seventy-two eggs were analyzed on day zero of storage, while the other eggs were stored at a temperature of 4 °C. The remaining eggs were analyzed after 10, 20, and 30 days of storage. The result revealed that, at 30 days of storage, the supplementation of terebinthus had a significant effect on the Haugh unit on inclusion levels of 20 and 40 g kg−1. Likewise, the inclusion level of 30 g kg−1 manifested a significant impact on yolk color at 20 days of storage. Eggshell breaking strength and egg weight remained unaffected. Terebinthus seed could be used to extend the storage time of eggs without any adverse effect on egg quality.
