With semi-lignified branches of 2-year-old C. surattensis, that haleness and no diseases and pests as the materials, and treatment with clean water as CK, the effects of 250, 500, 1000 mg/L indole butyric acid and 250, 500, 1000 mg/L naphthalene acetic acid on survival rate, plant height, average rooting number and root length of shoot were studied.

方法］以生长健壮、无病虫害2年生黄花槐的半木质化枝条为材料，以清水处理为对照，研究250、500、1000 mg/L吲哚丁酸和250、500、1000 mg/L萘乙酸处理对枝条成活率、株高、平均生根数及根长的影响。

It is fine to cultivate haleness seeding on MS+6-BA 0.1 mg/L+NAA 0.2 mg/L+sucrose30% medium. It is fine to rhizogenesis inducement on MS+BA0.01 mg/L+NAA0.2 mg/L ++sucrose30% medium.

采用MS+6-BA 0.1 mg/L+NAA 0.2 mg/L+蔗糖30 g/L培养基培养健壮苗较好，最佳生根培养基为MS+6-BA 0.01 mg/L+NAA 0.2 mg/L +蔗糖30g/L。

The results indicate that the type and concentration of the hormone has the remarkable influence on the induction of regrown shoots without roots, the different kinds of Hemerocallis middendorfii shoots without roots need different concentration of the hormone.

实验结果表明：不同浓度和种类的激素对大花萱草的生根效果不同；不同种类无根苗诱导所需的浓度也有所不同。

Using Hemerocallis middendorfii 's 6 varieties as experimental materials, we the investigated effects of hormone combination, types of explants, genotype and culture media on rooting of adventitious shoot.

摘要以大花萱草的6个品种为试材，主要研究了其组织培养中的激素配比、外植体类型、基因型以及不定芽的生根条件。

The stem apex of Hemerocallis fulva was taken as explant cultured in vitro to induce callus with different culture medium. The effects of different concentration 6-BA and NAA culture medium on explant growth was studied.

采取大花萱草茎尖为外植体接种在不同培养基上，研究了不同浓度的NAA和6-BA对于外植体生长的影响，并探索了最适于产生愈伤组织和生根的培养基配方。

In order to provide a theoretical base for rapid clonal propagation of new variety of Hemerocallis middendorfii（＂Baltimore oriole＂,＂ Bettry woods＂）that was imported from foreign countries, 1/2MS media containing different concentration of NAA and IBA were used to regenerate from Hemerocallis middendorfii re-grown shoots without roots.

为了快速繁殖从国外进13的大花萱草新品种，本试验中以"红运"、"奶油卷"无根试管苗为材料，以1／2MS为基本培养基，加入不同浓度的NAA和IBA作为外源激素，对大花萱草进行生根诱导。

The results show that NAT can effectively delaies the senescence of flag leaves and promotes both the development of roots of cutting leaves of hollyhock and the redifferentiation of young spikes of wheat culture in vitro, and also indicate that the effect of NAT is more remarkable than that of NAA.

结果表明，NAT可有效的延缓小麦旗叶的衰老，促进蜀葵叶柄的扦插生根和促进小麦幼穗离体培养的再分化作用。其效果比NAA更为明显。

Therefore, the activity of HA-K in regulating plant growth, and enhance the ability of plant drought resistance, and promote root, blossom and bear fruit to promote to increase production, improve quality of the performance is better than the activity of sodium humate.

所以，活性腐植酸钾在调节植物生长、增强植物抗旱抗寒能力、促进生根、促进开花结果、增加产量、提高品质等方面的性能优于活性腐植酸钠。

Chinese Christian music, especially Chinese hymnody, has long beenthe center of attention since the early 20th century.

自二十世纪初始，基督教圣诗音乐中国本色化问题一直是教会关注的焦点，基督教从一个"洋教"落地中国，生根开花结果，终于形成了中国本色化的教会，圣诗音乐本色化是其中的重要部分。

After the treatments of NAA and different levels of IBA, roots can be induced.

经NAA和不同浓度水平的IBA处理后，能有效促进魔芋组培苗的生根。

Fancy gold-plated dangling earrings with facetted White Opal crystals.

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
