子叶的

In this study, I compared cotyledon development in isocotylous European Gesneriaceae species to Streptocarpus rexii, their sister clade species with true anisocotyly. The results of cotyledon size measurement showed that European Gesneriaceae species exhibit nearly equal cell growth rate and thus maintain both cotyledons in the same size. But in Streptocarpus rexii, growth rate between macrocotyledon and microcotyledon was different thus altered cotyledon allometry growth.

我们藉由比较欧洲苦苣苔成员及仍具备子叶不等大发育的模式物种堇兰间的发育及形态差异，经由子叶面积大小的测量，欧洲苦苣苔成员两片子叶呈现相似的生长速率，因此维持两片子叶等大的特徵，然而堇兰的大小子叶的确具有不同的生长速率，使得堇兰两片子叶异速生长并造成堇兰子叶不等大的特性。

Either light or KT could induced cotyledon enlargement and they showed independent and additive effect on the response.

分析红光和蓝光与KT在促进子叶扩大中的作用，发现光与KT独立地调节子叶扩大反应，二者主要表现为加性效应。

The related factors of tissue culture were studied by using cotyledon of 7B7, self-hybrided Helianthus annuus L. as inducible material and MS as basic medium.

以油葵自交种7B7的无菌苗子叶为诱导不定芽材料，MS培养基为基本培养基，研究油葵子叶组织培养有关影响因子。

During development of the seedling, the hypocotyl forms the lower portion of the stem from the radicle up to the cotyledons

在幼苗发育期间，下胚轴从胚根到子叶的茎的下部形成。有许多形式的心理上的丑陋。

The morphology of M2 and M3 was observed in hothouse and mutants on cotyledon and root of seedling, or embryo of seed were identified. The result showed that there were 8 types of mutative treats on cotyledon, including light-yellow cotyledon, yellowish cotyledon, trump-shaped cotyledon, multilobed cotyledon, non-cotyledon, single-cotyledon, tricotyledon and quadrcotyledon.

M_2和M_3的水培和形态学观察的结果发现，子叶性状出现浅色、黄化、喇叭形、多耳突、无子叶、单子叶、三子叶、四子叶等8种变异类型；根系性状出现短小根、发达根、无侧根和弱向地性等4种变异类型；种胚性状中发现了多胚变异。

These isocotylous species thus provide a great opportunity to investigate how anisocotyly develop, and loses during Gesneriaceae evolution.

这些丧失子叶不等大的种，对比於仍具备子叶不等大的近缘种，提供了我们得以比较研究苦苣苔科子叶不等大发育机制的转化及其演化上的影响。

Anisocotyly is common in Gesneriaceae, which refers to that both cotyledon are unequally developed. The macrocotyledon can continuously grow while microcotyledon ceases to grow after cotyledon expansion.

子叶不等大是苦苣苔科植物特有的现象，在种子发芽后，其中一片子叶会藉由分生组织持续生长而成为大子叶，另外一片子叶则无法持续性的生长而形成小子叶。

Agrobacterium tumefaciens-mediated transformation system of Medicago truncatula cotyledonary-node explants Abstract The three-day-old seedlings of Medicago truncatula, which geminated in medium containing up to 5mg/L 6-BA, were used to prepare the cotyledonary-node explants which contained one cotyledon and 1-2mm of split hypocotyl. High-efficiency regeneration system of Medicago truncarula was developed by axillary shoot organogenesis of cotyledonary-node explants.

Of or relating to seed germination in which the cotyledons remain below the surface of the ground.

地下生的，地下产生子叶的种子萌芽的，或与之有关的，在这种萌芽里胚胎保留在地表面以下收藏反馈

The changes in cotyledons were observed in the third generation of the plants.

除绝大多数为正常的2片大小相等的子叶外，还出现了少数三子叶、漏斗状子叶和联生子叶。
