Heterosis in Japonica/Indica F1 Rice Hybrids with Special Reference to Nodal Root Function
Dry matter partitioning Heterosis Japonica/indica F1 hybrid Nitrogen uptake
2009/8/6
Although root system of japonica/indica F1 hybrids of rice (Oryza sativa L.) must play an important role for expression of heterosis, few studies have been conducted. This study was carried out to eva...
Heterosis for Root System Development in Japonica/Indica F1 Rice Hybrid
Heterosis Japonica/indica F1 hybrid Lateral root Nodal root Rice Specific root length Total root length
2009/8/4
Vigorous growth of F1 hybrid of rice (Oryza sativa L.) may be partially attributed to the development and function of the root system, but only a few studies have been conducted in this aspect. This s...
Growth and Yield of Japonica × Indica Hybrid Cultivars under Direct Seeding and Upland Cultivation Conditions
Direct seeding Dry matter production Emergence Growth High yielding ability
2009/7/23
Direct seeding is one possible improvement for future low-cost and labor-saving rice production. This study was conducted to determine whether high yielding cultivars can be adapted to direct seeding...

Japonica type rice line 9004, high yielding glutinous rice developed in Jiangsu Province, China, was cultivated with and without nitrogen at early tillering (ETS), spikelet differentiation (PFS I), s...
Floral Characteristics of Interspecific Hybrids between Spiraea thunbergii Sieb.ex Blume.and S.japonica L.fil
anthocyanin concentration flower bud differentiation hybrid Spiraea
2009/7/9
We investigated the flower characteristics of interspecific hybrids between Spiraea thunbergii Sieb. ex Blume. and S. japonica L. fil. via ovule culture. The flower bud differentiation of hybrid plant...
感光性不同的4个光敏感雄性不育粳稻经受14小时光周期下的31/27℃、31/22℃、31/17℃、27/22℃和27/17℃ 5种光期温度/暗期温度组合处理。考察其花粉育性的结果表明:1,在试验设计的光、温条件下,参试的不育品系都表现高度的光敏感雄性不育。但是,不同温度处理引起了败育水平的显著变化。2,光期温度下降4℃、暗期温度相同时,花粉育性极显著地增加;光期温度不变,暗期温度变动幅度为5℃时(...
