Factors affecting forage stand establishment Scientia Agricola
Sulc,R.M..
Significant advances have been made in our knowledge of forage seed physiology, technology, and stand establishment practices; however, stand establishment continues to be one of the most common production problems affecting forage crops in the USA. There is a need for research on stand establishment of forage crops under abiotic and biotic stress. Although the forage seed industry produces and markets seed of high quality, new methods of assessing seed vigor are needed and their use should be expanded in the industry to enable matching seed lot performance to specific environmental conditions where performance can be maximized. Seed treatment and seed coating are used in the forage seed industry, and studies have shown they are of benefit in some...

Performance of lowland rice seeds coated with dolomitic limestone and aluminum silicate Rev. bras. sementes
Tavares,Lizandro Ciciliano; Rufino,Cassyo de Araújo; Dörr,Caio Sippel; Barros,Antônio Carlos Souza Albuquerque; Peske,Silmar Teichert.
The objective of this study was to evaluate the performance of seeds of two cultivars of lowland rice (Oryza sativa L.), coated with dolomitic limestone and aluminum silicate. It was used a completely randomized experimental design, with the treatments arranged in a 4 X 2 factorial scheme [4 treatments: dolomitic limestone; dolomitic limestone + aluminum silicate; aluminum silicate, at the dosages of 50 g/100 kg of seeds; and control (without the products) X 2 cultivars: IRGA424 and IRGA 422 CL], totaling eight treatments with four replications each. The variables analyzed were: fresh and dry weights of aerial biomass; plant height; leaf area at 10, 20, and 30 days after emergence (DAE). The physiological quality of seeds was also assessed using tests of:...

Physiological quality of pelleted Cubiu (Solanum sessiliflorum Dunal) seeds Rev. Bras. Frutic.
Sprey,Layanne Muniz; Ferreira,Sidney Alberto do Nascimento; Sprey,Maylla Muniz.
Abstract The objective of this study was to evaluate the effect of different coating materials on the physiological quality of cubiu seeds. This was evaluated with three agglomerate materials (manioc starch, inert talc and dolomitic limestone) and two binder polymers (polyvinyl acetate and gum arabic) with 30% concentration, and artificial dye finishing. The experimental design was completely randomized, in factorial scheme 3 (agglomerates) x 2 (binders), and additional treatment (bare seeds/control), containing four replicates and experimental units of fifty seeds/pellets. The seeds were evaluated for: yield; seed/pellet diameter; thousand seed weight; number of seeds per pellets; germination; germination speed index; mean germination time, seedling...

Polymer coating, germination and vigor of broccoli seeds Scientia Agricola
Almeida,Celina de; Rocha,Sandra Cristina dos Santos; Razera,Luiz Fernandes.
Brassica oleracea var italica occupies a special place in the internal and external market of vegetables seeds. Vegetables producers demand seeds with high degree of purity, germination and vigor, since seeds' quality is the basis for the success of the production. In this work, broccoli seeds were coated in a spouted bed, by an aqueous suspension of hidroxy-ethyl-cellulose. Effects of the operating variables: spouting air temperature, atomizing air pressure and coating suspension flow rate over the dependent variables: seeds germination, seeds accelerated aging and the speed of seeds germination in soil, were investigated in a factorial scheme trial. The maximum processing time was 120 min. A totally randomized experiment evaluated and compared seeds...

การเคลือบเมล็ดพันธุ์ด้วยเพอลิเมอร์ร่วมกับ Rhodamine-B ต่อการเรืองแสงและคุณภาพเมล็ดพันธุ์มะเขือเทศลูกผสม Thai Agricultural
Chanoknet Chaiwicha; Boonmee Siri.
The objective of this experiment was to create identical seed by coating with fluorescent compounds. The experiment was conducted at Seed Technology Section of Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. The coating formulations were prepared using 1.5 % Hydroxypropyl Methylcellulose (HPMC) of fluorescent Rhodamine-B at the rates of 0.2, 0.4, 0.6, and 0.8 gram.The tomato seeds were coated by Centri Seed Coater (Model SKK 10). Coated seeds were subsequently divided into two parts. The first part; was used to detect fluorescence performance by hand-UV (Model UVGL-58; λ=365 nm.). The second part was used to evaluate the seed quality after coating and after accelerated aging with 100% relative humidity at 42oC for 74hours. It was found...
