Biochemical, histochemical and ultrastructural characterization of Centrolobium robustum (Fabaceae) seedsCaracterização bioquímica, histoquímica e ultraestrutura das sementes de Centrolobium robustum (Fabaceae)
(Instituto de San Paulo, 2009-03)
Centrolobium robustum seed coat is made up of an external layer of macrosclereids and an internal layer of osteosclereids, followed by a layer of dead cells. The endosperm is closely united to the seed coat and is made up ...
SEED LONGEVITY AND CRYOBIOTECHNOLOGY IN THE ORCHID GENUS Cattleya
(Cryo Letters, 2021-11-01)
BACKGROUND: Orchid seeds are reputed to be relatively short-lived, although comparative studies across a wide range of storage temperatures and moisture contents are few. OBJECTIVE: To explore how a wide range of temperature ...
Oxygen interacts with priming, moisture content and temperature to affect the longevity of lettuce and onion seeds
(CAMBRIDGE UNIV PRESS, 2011)
Lettuce (Lactuca sativa L.) and onion (Allium cepa L.) seeds have relatively short longevity during storage and their germination is sensitive to environmental stress. Seed priming (controlled hydration followed by drying) ...
Storage of Brazilian Cattleya seeds from diverse biomes: lipid composition and effects on germination
(2020-01-01)
The establishment of seed banks is essential for the conservation of cultivated and wild plant species. Cattleya species are economically important, but many of them are at risk of extinction. In this study, we aimed to ...
An extracellular lipid transfer protein is relocalized intracellularly during seed germination
(Oxford University Press, 2012-11)
Plant lipid transfer proteins (LTPs) constitute a family of small proteins recognized as being extracellular. In agreement with this notion, several lines of evidence have shown the apoplastic localization of HaAP10, a LTP ...
Maturation and Resting of Sweet Pepper Fruits on Physiological Quality and Biochemical Response of Seeds
(Inst Tecnologia Parana, 2021-01-01)
The post-harvest resting of the fruits can improve seed physiological quality ,once it allows the seed to complete the maturation process, so it has been a common practice in vegetable seed companies, however, there are a ...
