We carried out a seed germination experiment using two thrush species in captivity. We compared the number of germinated seeds and germination time of control seeds (manually removed from fruits) and ingested seeds of Miconia prasina by two bird species, Turdus albicollis and T. amaurochalinus, and also compared retention times of seeds by both thrush species. Control seeds germinated more freq...

Highlight Research Seeds can grow into seagrass seedlings for an optimal period of five weeks Seed sowing be optimized by supplementing nutrients with fertilizers The seedling transplant method, which utilizes seed seedlings, is not significantly different in daily growth from the anchor donors/seeds transport biomass content leaves used to determine rate Abstract Globally, area beds important ...

BACKGROUND AND AIMS Differences in dormancy and germination requirements have been documented in heteromorphic seeds of many species, but it is unknown how this difference contributes to maintenance and regeneration of populations. The primary aim of this study was to compare the seed bank dynamics, including dormancy cycling, of the two seed morphs (black and brown) of the cold desert halophyt...

Seed heteromorphism observed in many halophytes is an adaptive phenomenon toward high salinity. However, the relationship between heteromorphic seed germination and germination-related hormones under salt stress remains elusive. To gain an insight into this relationship, the roles of gibberellins (GAs) and abscisic acid (ABA) in regulating germination of Suaeda salsa dimorphic brown and black s...

We compared the physiological activities of sesame seeds rich in lignans from three varieties (Gomazou, Maruhime and Maruemon), and those from a conventional cultivar (Masekin) in rats. The sum of the values of fat-soluble lignans (sesamin and sesamolin) in seeds of Gomazou, Maruhime and Maruemon varieties was approximately double the value in Masekin. Seeds from Maruemon contained fat-soluble ...

BACKGROUND AND AIMS Hard-seeded (physical) dormancy is common among plants, yet mechanisms for dormancy release are poorly understood, especially in the tropics. The following questions are asked: (a) whether dormancy release in seed banks of the tropical shrub Parkinsonia aculeata (Caesalpiniaceae) is determined by wet heat (incubation under wet, warm to hot, conditions); and (b) whether its e...

Abstract Climate warming in mountain areas is increasing faster than the global average, threatening alpine plants. affects many traits including seeds, longevity of which important for conservation, facilitating genebank storage. Seeds species are considered short-lived storage, but their increases when produced under a warmer parental environment. Consequently, with climate warming, seeds may...

Research Highlights: This study is focused on the germination of Dracaena steudneri Schweinf. Ex Engl. seeds using different presowing treatments. Background and Objectives: The aimed to overcome problem breaking seed dormancy, facilitate artificial regeneration for conservation development purposes. objectives this were (1) evaluate effect treatments in dormancy D. (2) assess collection method...

In this contribution, the importance of banana seeds collected during archaeological investigations is indicated. Because fully-formed seeds are not ordinarily produced in bananas cultivated for food, the archaeological relevance of banana seeds may initially appear to be limited. However, there are a number of contexts in which the recovery and identification of seeds can be important for unde...

It is generally accepted that seedlings from large seeds are more tolerant to defoliation than those from small seeds due to the additional metabolic reserves present in the large seeds. However, information on the effects of amount of seed reserves (cotyledon removal) from seedlings resulting from large vs. small seeds on seedling growth and long-term survival in the field is limited. Five leg...
