Results For callus induction of leaf explants of C. orchioides, dark treatment gave better results compared to light treatment; among the media tested, the suitable phytohormone combinations were 2.0 mg/L 2, 4-D or 6-BA 1.5 mg/L 2, 4-D 2.5 mg/L, and 300 mg/L CH 0.2% AC was good for plantlet regeneration from leaf explants. The callus from leaf explants mainly originated from midrib. The parenchyma cells near epicuticle of midrib firstly were initiated to division. Then the parenchyma cells of vascular bundle sheath and mesophyll cells on each side of vascular bundle were also divided to form callus.

结果对仙茅叶片的愈伤诱导，黑暗的效果好于光照；在所试验的培养基成分中，适宜的激素配比是2.0mg/L2，4-D或6-BA1.5mg/L 2，4-D2.5mg/L，并且附加300mg/L水解酪蛋白和0.2%活性炭，对于仙茅叶片的离体成苗较好；培养后，愈伤组织主要由叶片的中脉产生，位于中脉上表皮内侧的薄壁细胞首先启动分裂，随后维管束鞘薄壁细胞及其外侧的叶肉细胞也启动分裂，参与愈伤组织的形成。

The number of fruits had the highest directly positive relationship with seed yield,followed by leaf length,collar diameter,length of bearing branch,hundred-seed weight,the number of branches,angle of bearing branches,the height of bearing branches and plant height;five of 14 seed yield components exhibited directly negative relationships with seed yield,including leaf width,ratio of leaf length to width,the number of bearing branches,bottom diameter of bearing branches and ratio of bearing branches to branches.

2果实数对种子产量的直接正效应最大，其后依次是叶长、地径、结果枝长、百粒重、分枝数、结果枝角度、结果枝高度和株高；14个产量因子中有5个对产量有直接的负效应，包括叶宽、叶长宽比、结果枝数、结果枝底径和结果枝比。

结果表明，与传统的比叶面积法和有效积温法相比，辐热积法显著提高了温室番茄叶面积的预测精度，提高了光合作用和干物质生产的模拟精度。

The most significant variance lay in the 1000-seed-weight,followed by flag leaf length and inflorescence shape and then by distance between flag leaf and inflorescence with least in inflorescence length,plant form,leaf width and seed length.Meanwhile,morphological characteristics of D.glomerata have significant relationships: those with upright and constrictive inflorescences hav...

其中，种子千粒重变异最大；旗叶长度、花序形状次之；穗叶距、花药宽度、旗叶宽度等性状变异中等；而花序长度、株型、叶宽、种子长度变异最小。2鸭茅植物形态学特征间存在明显相关性，花序直立、紧缩的鸭茅，叶片窄长，茎秆粗壮，旗叶较长，雄性生殖器官发育良好，结种性能强；而花序下垂、开展的鸭茅则与之相反。3聚类分析表明，不同野生鸭茅种源可划分为3类，其中花序下垂种源聚于一类；而花序直立的种源分居另两类。4从形态学特征及相关农艺性状分析，花序直立的鸭茅更具开发利用潜力。

Fifteen japonica and 15 indica rice cultivars were grown in the field for two crop seasons both in Taipei and Taichung. Samples were taken at 4 different growth stages (booting, heading, milky and dough stage) during each season to obtain data of leaf atea index, leaf area duration, leaf N concentration, the amount of dry matter accumulated , crop growth rate, and net assimilation rate.

本试验以稉秈稻各十五个品种为材料，分别於台北及台中进行两期作之田间试验，并於孕梗期、抽梗期、乳熟期及糊熟期取样，测定叶片氮素浓度、叶面积及总乾物重，并求叶面积指数、叶面积持续期、作物生长速率及净同化率。

Removing 3/4 ear treatment accelerated flag leaf senescence, and delayed the top 2nd leaf and top 3rd leaf senescence.
