Matriconditioning is a technique that aims to standardize and accelerate the germination of seeds and the emergence of plantlets. The objective of the study is to evaluate the effect of that methodology under the physiological performance of amaranth seeds. The experiment used two lots of seeds at the Universidade Tecnológica Federal do Paraná (UTFPR), Campus Dois Vizinhos (Parana State). Plastic boxes of the Gerbox type were the matriconditioning environment, containing 55.5 g of sterile vermiculite moisturized with distilled water at 100% of the retention capacity. Plastic boxes were placed in a germination chamber at ten degrees Celcius. Four repetitions of 100 seeds had their weight measured at 0, 2, 4, 8, 16, and 32 h after the procedure started to obtain the curve of imbibition. The following tests were performed after each period: Germination test, first germination count; length and dry mass of plantlets; emergence speed index, and accumulated emergence tests. Amaranth seeds achieve phase II of germination around 8 h of imbibition by matriconditioning. The effect of matriconditioning in the physiological performance of amaranth seeds varies as a function of the used lot.
Solid matrix priming (matriconditioning) permits slow seed hydration, and germination and emergence period reduction. In general, seeds need to be soaked to start their germination process. The objective of this study was to evaluate the effect of the matriconditioning under the imbibition curve and the physiological performance of two lots of chia seeds with different qualities. The study was performed with chia seeds harvested by small-scale farmers. To estimate the imbibition curve, seeds from both lots were started in the imbibition process on a stainless-steel screen placed in plastic boxes, containing 55.5 grams of sterilized vermiculite and moisturized with distilled water at 100% of their retention capability. The imbibition curve weights were made 0, 2, 4, 8, 16, and 32 hours after the process had started. Simultaneously, in each evaluation period, seeds were submitted to the following tests: germination, first count of germination, plantlet shoot, root and total lengths, emergence velocity index and average time, and accumulated emergence. A completely randomized experimental design was used. It was possible to conclude that the beginning of phase II of germination in matriconditioned seeds varies in function of the chia seeds' lot quality. The matriconditioning contributes to the physiological performance, increasing and accelerating plantlets' emergence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
