Germination of parsley seeds influenced by mericarps color and internal morphology

Abstract

The objective of the present study was to establish a relationship between mericarps color and internal morphology of parsley with the germination, using sorting by coloration and the X-ray test. The completely randomized design was used, with four replications per treatment. The treatments were constituted of four lots (A, B, C and D) and three mericarps colors (green, yellow and black) in 4×3 factorial experiment. The mericarps were exposed to X-ray test (60s; 20kV), being used the digital equipment Faxitron X-ray, model MX-20 DC12 and then, the irradiated mericarps were submitted to the germination test. The yellow mericarps showed higher germination and speed germination index. The green mericarps showed deformations and impaired formation of embryo, while black and yellow mericarps showed up without deformation and with a well-formed embryo. We concluded that there is a relationship between parsley seed germination and mericarps color. Poorly formed embryos and misshapened seed coats are related to green mericarps.

Determination of Chlorophyll and Carotenoids Present in the Seeds of the Plant Family Apiaceae and the Impact on Seed Quality

“…In the case of parsley variety "Lisa Preferida", represented by four commercial lots, 62 -63 % germination was lower than the minimum recommended for certified seed commercialization (80 %) and energy of germination had values 51 -56 %. Sorting seeds by coloration of mericarps enabled to reach in some cases germination values from 80 % to 88 %, and energy of germination ranged from 46 % to 62 % (Oliveira et al, 2013). In our results, the germination values reached the minimum recommended for certified seed commercialization and energy of germination ranged from 65 to 90 %.…”

POTENCIAL FISIOLÓGICO DE SEMENTES DE FEIJÃO-GUANDU (Cajanus cajan (L.) Millsp.) ASSOCIADO À COR DO TEGUMENTO

“…As sementes de feijão guandu têm coloração verde ou púrpura quando imaturas e quando maduras podem apresentar cor branca, amarela, castanha, preta e claras salpicadas de marrom ou púrpura (SEIFFERT; THIAGO, 1983). Muitos fatores estão relacionados com a coloração do tegumento das sementes, dentre eles a maturação irregular, ocasionada pela desuniformidade no florescimento, pelo processo de deterioração e pela composição química (OLIVEIRA et al, 2013;MARCOS-FILHOS, 2015;GULARTE, 2019).…”
