1) panicle developmental stage
幼穗发育时期
1.
Comparative analysis of changes in soluble protein content in leaves, panicles and anthers among homozygous and heterozygous sterile plants and recessive fertile plants of Pingxiang Dominant Genic Male Sterile Rice (PDGMSR) in different young panicle developmental stages was conducted.
结果表明,显性核不育水稻3种不同基因型植株在幼穗发育时期叶片中的可溶性蛋白质含量差异不大,且变化趋势相同;不育株(纯合与杂合)幼穗中可溶性蛋白质的含量在雌雄蕊形成期与可育株基本相同,而在花粉母细胞形成期和花粉母细胞减数分裂期迅速下降;不育株(纯合与杂合)花药内可溶性蛋白质含量明显低于可育株,这是不育株花粉败育的一个重要生理特征。
2) dual-purpose genic male sterile line
幼穗发育
1.
The dual-purpose genic male sterile line indica rice Pei ai 64S and conventional rice cultivar Jingxian 89 were used as experimental materials.
以籼型两用不育系水稻培矮645和常规稻粳籼89为材料，采用PAGE分析同工酶的方法，比较水稻幼穗发育过程中花粉母细胞形成期、减数分裂期和花粉完熟期NAD＋-MDH和AP同工酶的变化，以期了解不育系的育性转换与表达机理。
3) young spike differentation and developmental
幼穗分化发育
5) nympha stage
幼虫发育期
6) Developmental stage
发育时期
1.
The results showed that the developmental stage of floral receptacle affected the differentiation of callus,and the best effect was floral receptacle of inflorescence which diameter was below 0.
采用处于不同发育时期的非洲菊花托作为外植体,以1/2 MS+6-BA10mg/L+NAA1mg/L为诱导分化培养基进行组织培养研究。
2.
The anatomical structure of the ovules at different developmental stages of Pinus tabulaeformis in Beijing was observed by microscopy to determina the ovule development of P.
采用显微观察法对北京地区不同发育时期的油松胚珠进行解剖结构观察,以确定北京地区油松胚珠的发育时期。
3.
The hyperspectral reflectances of the canopy, the first and the third unfolding leaf from the top and panicles of two rice varieties were measured by a ASD FieldSpec Pro FR TM in field and indoor under three nitrogen levels at different developmental stages.
通过大田和室内试验 ,测定了 2个品种、3个供氮水平处理的水稻冠层、完全展开倒 1叶、倒 3叶和穗在不同发育时期的高光谱反射率及对应叶片和穗的叶绿素、类胡萝卜素含量。
