Eastern gamagrass [Tripsacum dactyloides (L.) L.] is currently being selected for higher forage yield. A prolific variant which can produce up to 20 times the number and 3 times the weight of seeds of a normal plant was found in a wild population and is now instrumental in the breeding program. Could this prolific type spread in wild populations? Vegetative vigor of mature plants was assessed b...

Abstract: The association between beneficial microorganisms and green beans can accelerate establishment in the field. objective of this study was to investigate influence seed treatments different doses Bacillus subtilis on physiological potential beans. Seeds from cultivar Macarrão Baixo were used. used a completely randomized design double factorial scheme with factor A treatments: Pellicula...

Abstract Sowing in dry soil aims to alleviate the effects of water restriction, allowing for an earlier start sowing and maximizing operational productivity use agricultural machinery implements. Thus, objective present work was evaluate physiological quality soybean seed lots submitted different periods deficit after under vegetal cover. The experimental design completely randomized, a 2x5x2 f...

scribed by a normal distribution Understanding the survival characteristics of hybrid corn (Zea y 5 [1/s√2p]exp[2(p 2 p)2/2s2] [1] mays L.) seed during storage is necessary to predict seed deterioration. This investigation tested one key assumption of the Ellis and Roberts where y is the relative frequency of deaths occurring at viability equation, namely, that seed survival is normally distrib...

Seeds provide food, feed, fiber and fuel. They are also an important delivery system of genetic information, which is essential for the survival of wild species in ecosystems and the production of agricultural crops. In this review, seed traits and genes that are potentially important for agricultural applications are discussed. Over the long period of crop domestication, seed traits have been ...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...
