| The species Syngonanthus elegantulus Ruhland is an important native plant used as cut flowers, but extractive exploration has caused the endangered status of this plant. Therefore, the objective of this study was to establish a protocol of the micropropagation of S. elegantulus. To this end, seed germination was tested in media containing different concentrations of WPM salts. For plantlet establishment, MS and WPM media were evaluated with 50 and 100% of the salt concentrations. Different the sucrose levels in the WPM medium were also evaluated. For multiplication, the plantlets were inoculated in WPM media with 0.0, 0.5, 1.0, 2.0 and 4.0 mg L-1 TDZ and 0.0, 0.5 and 1.0 mg L-1 NAA in all possible combinations. The pre-acclimatization effect was tested in... |

| ABSTRACT Water management and meteorological conditions during the cropping phase play an essential role in maintaining the commercial quality of cut flowers. This study evaluates water requirement, sensitivity to water deficit, and commercial quality of gladiolus ‘Amsterdam’ produced with automated irrigation in different growing periods. The experimental design was in randomized blocks with five replicates and consisted of the growing period factors (winter/spring 2018 and autumn/winter 2019) and the irrigation level factors (45% - L1, 60% - L2, 80% - L3, and 100% - L4 of crop water requirement). An automatic irrigation controller was used for irrigation management. At the harvest point, we evaluated the stems for the diameter, number of flowers, spike... |

| O estudo teve como objetivo avaliar a influência da qualidade fisiológica de diferentes lotes de sementes de rúcula (Eruca sativa L.) no desenvolvimento inicial e na produção comercial. Avaliou-se a qualidade fisiológica das sementes mediante testes de germinação, primeira contagem de germinação, índice de velocidade de germinação, comprimento da raiz primária e da parte aérea, massa fresca e seca de plântulas. Aos 10 dias após a semeadura em campo, avaliou-se a percentagem de emergência, comprimento de raiz e da parte aérea, massa fresca e seca das plântulas. Aos 35 dias após a semeadura, foram avaliados o número de folhas, número de folhas maiores que dez centímetros, massa fresca e seca das plantas. O delineamento experimental foi inteiramente... |
