Yunnanopilia longistaminea is an endangered monotypic species belonging to Opiliaceae. This edible plant is an important germplasm source with a high economic value in China if propagation were less difficult. Seed dormancy and germination of this species were investigated to improve propagation. Considering seeds have a fully developed embryo and mature and are dispersed in summer, and radicle...

BACKGROUND AND AIMS Seed quality may be compromised if seeds are harvested before natural dispersal (shedding). It has been shown previously that slow or delayed drying can increase potential quality compared with immediate rapid drying. This study set out to investigate whether or not there is a critical moisture content, below which drying terminates maturation events for seeds harvested afte...

Production of high quality seeds is of fundamental importance for successful crop production. However, knowledge of the effects of increased temperature resulting from global warming on seed quality of alpine species is limited. We investigated the effect of maternal environment on seed quality of three cultivars of the leguminous forage species Vicia sativa, giving particular attention to temp...

The species composition of micromycetes Scots pine seeds, collected from plantations growing in different forest vegetation conditions and selected trees age groups, was studied. It found that the most common - Alternaria alternata, Cladosporium cladosporioides, Fusarium oxysporum, Mycelia sterilia. Dominant micromycetes, particular Penicillium cyclopium, sambucinum, which are dangerous for dev...

Physiological and morphological changes in the ovarian system in rice weevils, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), reared on wheat seeds were studied as a function of adult age, mating status, and nutrient availability. X-ray analysis was used to determine time of adult eclosion and the duration of development of pre-emergent weevils within the seeds, a process that lasted almos...

Alternative splicing (AS) is a key modulator of development in many eukaryotic organisms. In plants, alternative splice forms of non-coding RNAs (ncRNAs) are known to modulate flowering time in Arabidopsis and fertility in rice. Here we demonstrate that alternative splicing of coding and long non-coding RNAs occurs during rice seed development by comparing AS in immature seeds vs. embryo and en...

Momordica charantia L. (cucurbitaceae), is a plant whose fruits are widely consumed in Chad. Seeds, green and ripe pulps of the this were subject study. The total polyphenols, antioxidants, flavonoids anthocyanins evaluated by Folin - Ciocalteu, DPPH, iron trichloride pH-differential methods respectively. polyphenol obtained 9.368 mg GAE/g for seeds extract, 9.068 pulp extract 8.505 mature extr...
