  “繁茂生长”译为未确定词的双语例句
    When the induced callus was transferred to 2, 4-D free MS medium,budgensis was observed about 2 weeks afterward only by the addition of 6-BA alone. Rootgensis of the bud was stimulated by NAA and 6-BA added to the MS medium thereafter. Finally, the completed plantlet could be obtained.
    单独的外源生长素2,4-D适宜诱导外植体脱分化产生愈伤组织,只有单独添加6-BA时,才适宜再生芽的分化,当NAA与6-BA配合添加培养基中,则有利于再生根的繁茂生长,从而形成完整的再生植株。

The growth of Ariemisia ordosica, which is the main communityconstructing species, appears in some locations in the Maowusu sandland. Cynanchum komarocii, a perennial species; however, grows luxurantly throughout the area. There is obviously succession between these two species in experimental area. The characteristics of the two species are explained by our investigation based on physiological ecology, reproductive biology and by the analysis of fundamental elements of the environment.A. ordosica and C. komarovii...

The growth of Ariemisia ordosica, which is the main communityconstructing species, appears in some locations in the Maowusu sandland. Cynanchum komarocii, a perennial species; however, grows luxurantly throughout the area. There is obviously succession between these two species in experimental area. The characteristics of the two species are explained by our investigation based on physiological ecology, reproductive biology and by the analysis of fundamental elements of the environment.A. ordosica and C. komarovii are characteristic of anisohydric and isohydric plants respectively.

作为毛乌素沙地植被主要建群种的油蒿(Artemisia ordosica)在一些地方出现了不同程度的退化,而萝藦科的一种多年生草本植物牛心朴子(Cynanchum komarovii)却出现了繁茂的生长。它们之间存在着一定的演替关系。本文通过对油蒿和牛心朴子的生理生态学特性和生殖生物学特性的研究及对其生境各要素的分析,说明了油蒿具有变水植物的特点,牛心朴子具有恒水植物的特点。在不同立地条件下,两种植物的光合、蒸腾及气孔行为都不相同。即便是在相同立地条件下,牛心朴子的水分利用效率亦显著高于油蒿;并且,牛心朴子只受轻微水分胁迫或不受水分胁迫,而油蒿则始终处于水分胁迫之下,说明牛心朴子在竞争中比油蒿占有相对的优势。在生态诸因子中,土壤水分状况是演替的外因,两种植物的水分生理生态特性和生殖生物学特征的差异是演替的内因。

The study shows the ranges of genetic variation of choline concentrations in flowering spikes among bread wheat varieties, the correlation of both the choline concentrations and the resistances to wheat scab [Gibberella zeae (Schw) Petch] and the action-patterns of a higher concentration of choline to wheat scab. The conclusions are as follows in brief.I. The choline concentrations in flowering spikes among bread wheat varietes are of significant difference and the variation is hereditary.Ⅱ.

The study shows the ranges of genetic variation of choline concentrations in flowering spikes among bread wheat varieties, the correlation of both the choline concentrations and the resistances to wheat scab [Gibberella zeae (Schw) Petch] and the action-patterns of a higher concentration of choline to wheat scab. The conclusions are as follows in brief.I. The choline concentrations in flowering spikes among bread wheat varietes are of significant difference and the variation is hereditary.Ⅱ. The correlation coefficents between the choline concentrations (Y) and the dis-eased spikelet ratioes (X1) or the disease reaction indexes (X2) are all of statistical sig-nificance, in the identifications of the resistance to infection (r=-0.9762) and of the resistance to disease spread (r1=-0.8634, r2=-0.8871). Therefore, the choline concen-tration in flowering spikes can be as one of the most important physiological characters concerning with resistance to wheat scab.Ⅲ. Besides anthers at anthesis, pistils and young caryopses are rich in choline and are the main sites of the initial infection. Choline in the sieve tubes of spikes stimulates mycellium spread. And in the spike chloroplast tissue, a higher concentration of choline can be as important nutriments for mycelliuni development to form sporodochia on the spike surface.It's suggested that utilizing the varieties with a lower concentration of choline in flowering spikes in wheat breeding may be beneficial to improve the resistance for wheat scab.

研究表明,(1)普通小麦品种间盛花期穗胆碱浓度存在着极显著差异;系谱分析表明这一生理性状具有遗传性。(2)盛花期穗胆碱浓度与赤霉病田间抗性之间呈极显著负相关,即与病圃病小穗率、反应级值均呈极显著正相关(r_1=0.8634),可作为筛选小麦赤霉病抗源的重要生化指标之一。(3)富含胆碱的残留花药、雌蕊及早期颖果是禾谷镰孢菌的主要初侵染源;富集在穗轴和护颖表皮层叶绿素组织的胆碱则可能作为“分生孢子座的营养源”,刺激菌丝由此滋生并伸至穗表面形成分生孢子座,散发分生孢子进行再侵染;穗筛管汁液中的咀碱刺激菌丝沿着维管束扩展并在维管束节处繁茂生长。因此,胆碱不仅影响小麦抗赤霉病侵染性(r=0.9762),也影响抗扩展性(r=0.8871)。

The callus of plantago strain "Tuling" was induced by 2,4-D. After the induced callus removed to 2,4-D free MS medium with 6-BA added, budgenesis was observed about 2 weeks later. Rootgenesis of the Bud was stimulated by NAA and 6-BA added to MS medium.Finally, the completed plantlet could be obtained.

报道了车前外植体的愈伤组织诱导及其植株再生的研究结果。单独的外源生长素2,4-D适宜诱导外植体脱分化产生愈伤组织;再生芽的分化只需添加6-BA;当NAA与6-BA配合添加于培养基中时,则有利于再生根的繁茂生长,从而形成完整的再生植株。
