盐害是制约全世界作物生长的主要非生物胁迫之一,全球有6%土地和20%灌溉用地受到盐害影响,严重制约了农作物生长发育和产量。水稻作为全球主要粮食作物之一,对盐胁迫敏感。盐胁迫条件下,水稻种子萌发和幼苗形态建成显著受抑制,严重制约了我国水稻直播的推广和盐碱地区耕地利用。因此,挖掘鉴定控制水稻种子萌发的关键基因,阐明其在盐胁迫条件下调控种子活力的分子机制,对培育适合盐碱地生长的种子高活力耐盐水稻品种和保...
团队全面系统论述了植物激素脱落酸(ABA)在种子的成熟、休眠和萌发过程中的最新研究进展,总结了脱落酸通过含量变化和信号转导的调节来参与种子发育不同阶段的分子机制,提出了脱落酸与其他不同的激素、代谢物质等信号分子互作调控种子发育的模式图,对于揭示脱落酸介导的种子发育过程的分子调控网络具有重要意义。
NF-YCs are important transcription factors with diverse functions in the plant kingdoms including seed development. NF-YC8, 9, 10, 11 and 12 are close homologs with similar seed-specific expression pa...
Calanthe tsoongianaT. Tang et F.T. Wang, a terrestrial orchid that is endemic to China, has become rare and endangered due to limited natural reproduction and habitat destruction. There is an urgent n...
Two varieties of barley samples were subjected to germination conditions to investigate the underlying mechanisms underpinning changes in molecular structure, chemical compositions and thermal propert...
This study investigated methods to overcome seed dormancy in Crataegus pseudoheterophylla Pojarkova seeds. Seeds with and without endocarps were treated with gibberellic acid (GA3) at different conce...
In 2014, this research was conducted at the Research Institute of Horticulture in Skierniewice, Poland. It was based on different red raspberry seed treatments with sulfuric acid during the scarifica...
Seed germination experiments with Corylopsis coreana, C. sinensis var. calvescens, and Corylopsis gotoana were conducted. Corylopsis coreana seeds were treated at 5o, 7.5o, 10o, 12.5o and 20oC to stu...
Service tree (Sorbus domestica L.) is a significant species with regard to the biodiversity of specific habitats. Its reproduction in natural conditions appears to be problematic and in the interest o...
Seedlots of sycamore maple (Acer pseudoplatanus L.) originating from three different provenance regions were collected in autumn 2012. The seed quality, namely vitality and germination rate, was asses...
The effect of different concentrations of brassinosteroids (1:10, 1:100, 1:210) on the germination of sycamore (Acer pseudoplatanus L.) and ash (Fraxinus excelsior L.) seeds was investigated in stre...
Sycamore (Acer pseudoplatanus L.) seeds are frequently used in forest nurseries and therefore the knowledge of their proper treatment is desirable. Seed stratification recommended by the Czech standar...
One of the critical points of Douglas fir seedling production is to optimize the time of sowing and length of pre-sowing treatment. Germination and emergence of Douglas fir seed lot of the Czech ori...
Germination capacity and germination energy are usually the most frequently used quantitative parameters of forest tree seed. With seed ageing both parameters decreased and the rate of the collapse is...
The effect of ethephon (80, 100 and 120 mg·l–1) and gibberellic acid (GA3) (40, 300 and 1,000 mg·l–1) on the germination capacity (GC) and mean germination time (MGT) of European beech (Fagus sylvatic...
