Abstract The process of seed germination is described as the culmination a series events that start with wetting and end emergence embryo (typically radicle) from coat. This method has an impact on crop output quality. characteristics surface surroundings have kinetics volume water absorption by seeds. As result, modifying seed's useful tactic for influencing germination. Low-temperature plasma...

The present work evaluated the germinability and vigor of Croton urucurana seeds. 1) Seeds were sorted by color (caramel, gray and black) and were subjected to seven different pre-germination treatments followed by incubation at 20ºC, 25°C or 20/30°C. 2) Seeds were stored in cold chambers or at room temperature for up to 300 days and were subsequently incubated at 20/30ºC in a germination chamb...

This study aims to determine the effect of pre-emergence application herbicide metsulfuron methyl on soil mixed with rice husk biochar germination weeds. used a factorial completely randomized design (CRD) two levels (0 gr/ha and 300 gr/ha) four (0%, 5%, 10%, 15% total weight planting medium). The parameters observed were number weeds, wet dry results showed that interaction had no significant ...

Luffa aegyptiaca (Luffa sponge gourd) is increasingly seen as both a source of vegetative nutrition and as a source of the “luffa” used as to exfoliate during bathing. As such, the commercial growing of Luffa aegyptiaca is increasingly being investigated using more intensive farming methods. Two factors traditionally used to promote / speed germination and emergence of vegetable seeds is invest...

The mechanism of influence the UV- radiation biological processes into seeds agricultural plants is considered. technical parameters installation for pre-sowing treatment with ultraviolet lamps increasing permeability membranes cells in seed are defined. results experimental researches on have established that processing cotton treated rays, their germination and productivity crops shown.

The aftereffect’s study of pre-sowing treatment with electric current 500V, 1000V and 8000V on the sowing qualities growth processes corn hybrid seeds Rodnik 180 SV was carried out in laboratory conditions. As a result conducted studies, positive effect electrical stimulation germination energy revealed. Studies have shown effectiveness seeds’ according to following traits: roots seedlings, see...

Despite proposed ecological importance of mucilage in seed dispersal, germination and seedling establishment, little is known about the role of mucilage in seed pre-germination processes. Here we investigated the role of mucilage in assisting achene cells to repair DNA damage during dew deposition in the desert. Artemisia sphaerocephala achenes were first treated γ-irradiation to induce DNA dam...

Infection structures were observed at the penetration sites on the leaves of cucumber plants inoculated with Colletotrichum orbiculare using a fluorescence microscope. The cucumber plants were previously drenched with suspension of bacterial strains Pseudomonas putida or Micrococcus luteus. The plants pre-inoculated with both bacterial strains were resistant against anthracnose after inoculatio...
