Apesar da propagação de mandioca ser efetuada vegetativamente para fins comerciais, a maioria dos acessos mantém ativo o sistema de propagação sexual, o que é fundamental para programas de melhoramento genético. Entretanto, as sementes de mandioca apresentam germinação baixa e desuniforme. Considerando este fato, o objetivo deste trabalho foi avaliar a eficiência do armazenamento, e de diferentes tratamentos pré-germinativos, na emergência de plântulas de mandioca. Para isso, foi conduzido um experimento com sementes originadas da polinização aberta entre plantas de quatro variedades de mandioca de mesa, nas quais foram testados 10 tratamentos pré-germinativos, mais a testemunha. A viabilidade das sementes submetidas aos tratamentos foi avaliada pelo teste...

ABSTRACT New and refined technologies based on computerized procedures create the potential for automating laboratory evaluations, constituting an alternative to reduce costs and increase the decision-making capacity regarding the destination of seed lots. The objective of this study was to evaluate the efficiency of the Sistema de Análise de Plântulas (SAPL ®) free digital image processing software of seedlings in characterizing the physiological potential of maize seeds in comparison with information provided by vigor tests recommended for this species. Ten lots of maize seeds were submitted to germination, first germination count, germination speed index, seedling emergence, cold test and electrical conductivity. The results of these tests were compared...

The objective of this experiment was to investigate effect of accelerated aging after sweet pepper seeds were primed with two types of chemical solutions. The experiment was conducted at Seed Technology Laboratory Section in Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. The sweet pepper seeds were soaked in two types of solutions: 1) 2.5%Chitosan 2) 2%KNO3 at 15oC for 5 hours. Primed seeds were subsequently subjected to accelerated aging at 42oC with relative humidity 100% for 10 days. The effects of seed priming on seed quality were determined after priming. The results showed that the primed seeds had seed germination percentage and speed of germination higher than non-primed seeds. It also showed that it had seed vigor more than...

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...

Kittiwan Klarod; Boonmee Siri.
A study of different type and proportion of polymers were investigated on tomato seed quality. This experiment was conducted at seed technology laboratory, Seed Processing Plant, Faculty of Agriculture, Khon Kaen University. Using three polymers type polyvinyl pyrrolidone (PVP-K30), polyvinyl pyrrolidone (PVP-K90) and polyvinyl alcohol (PVA). This experiment consisted of 2 parts. The first part of experiment was to study effect of type and proportion of polymers as a film former on viscosity, dissolution of film-sheet. The second part, study the effect of seed coating substances on tomato seed quality. Seven treatments were compared: uncoated seed, seed coating with PVP-K30, PVP-K90 and PVA. The tomato seeds were coated by centri seed coater model SKK 10....

The experimental study design was used to examine the effects of accelerated aging on deterioration of seed quality and electrolyte leakage of cucumber seeds. The original cucumber seeds had 99 germination percentage. The cucumber seeds were taken to accelerated aging process; in aging chamber with constant temperature 450C and 100% of relative humidity for 0-21 days. The seeds were taken every three days for 3, 6, 9, 12, 15, 18, and 21 days and tested of seed quality. After that, the seeds were divided into 2 lots. The first lot was examined for conductivity values and measured K+, Ca2+, Na+, and Mg2+ leakage. The second lot was examined seed quality under laboratory and green-house conditions. Additionally, The results were shown that after 6th days of...
