Although fungi cause a recognized problem during storage of recalcitrant seeds of many tropical species, there are no data to date on defence strategies of these seeds against fungal attack. To ascertain whether recalcitrant seeds of Avicennia marina elaborate compounds that might suppress fungal proliferation during hydrated storage, the production and efficacy of beta-1,3-glucanase (EC 3.2.1....

Lotus seeds were identified by the Ministry of Public Health of China as both food and medicine. One general function of lotus seeds is to improve intestinal health. However, to date, studies evaluating the relationship between bioactive compounds in lotus seeds and the physiological activity of the intestine are limited. In the present study, by using medium pressure liquid chromatography coup...

Since uncharred seeds recovered from archaeological deposits may be modern intrusions, researchers must evaluate each uncharred seed assemblage before assigning archaeological significance to it. When depositional circumstances are established, seed remains can yield primary data about diet, farming practices, and the spread of imported cultigens. Three uncharred seed assemblages are evaluated—...

Limits on Efficient Computation in the Physical World

in order to assess drought stress and planting date effects applied on original plant, on the electrical conductivity rate of the subsequent seeds, this research was performed in two parts at the research field and laboratory during spring 2008. the field experiment was performed as a completely randomized block design (crbd) with 20 treatments and three replications. treatments included the se...

The movement of pollen between crop and wild sunflowers (both Helianthus annuus) has led to concerns about the possible introduction of crop transgenes into wild populations. The persistence of crop traits in wild populations will depend in part on the relative fitness of crop-wild hybrid vs. wild plants. Using seeds from two large experimental field plots, we found that seeds produced by crop-...
