多子叶的

Many of the embryoids were abnormal , such as monocotyledon and polycotyledon.

部分体胚有畸形的表现，单子叶、多子叶、子叶联合。

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.

Seeds with bony tegument; endosperm thin; cotyledons oblate, rounded; radicle short.

种子有多骨的皮；胚乳薄；子叶扁球形，绕行；胚根短。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。

Plantlet regeneration from cotyledon of Citrullus lanatus cv. Zhangkang No. 4 was studied. The results showed that aseptic seedlings should be cultured in dark for 3d, then exposed to a photoperiod of 16/8h/d for 3d. The callus induction rate was higher in cotyledons placed facing downwards to the medium than in those facing upwards. The highest induction rate occurred in MS medium containing 6-BA (2.0mg/L), kinetin (1.0mg/L)and GA3 (1.0mg/L). The induction initiated in dark and took 7 days, while callus growth and differentiation proceeding for 7 days under 16/8h light-dark cycles. A highest rate of embryogenic callus was obtained after 3 successive subcultures.

以无子西瓜郑抗4号无菌苗子叶为外植体，进行了体细胞胚发生及植株再生的研究，结果表明，无菌苗应先进行3d暗培养，然后采取光照16h/d和黑暗8h/d培养3d；将子叶的叶面朝下放置于培养基上的愈伤组织诱导率高于叶面朝上的培养方式；子叶诱导胚性愈伤组织的最适培养基配方为MS+6-BA2.0mg/L+KT1.0mg/L+GA31.0mg/L；诱导需要在黑暗条件下启动，进行7d暗培养，而生长分化于光照16h/d和黑暗8h/d条件下培养7d；继代3次得到的胚性愈伤组织最多；最适生根培养基配方为1/2MS+IBA0.3mg/L。

As time of accelerated aging increased,abscisic acidcontent of cotyledons andaxes was increased dramatically.ABA contentwas 4 times more in seed axes aged for 5 daysthan in unaged ones and 1 time more in cotyledons.

随着人工加速老化，菜用大豆种子胚轴、子叶内ABA含量都呈增加的趋势，老化5天种子胚轴内ABA含量为未老化的5倍多，子叶内则为2倍多。

The coconut tree has many uses: Coconut tree Shui Fuhan the protein, the fat and the multivitamins, the promotion cell grows again, may drink, the sweet solution hot weather, the mesophyll and massive can sober up including 35.5% fat, be helpful the zinc which synthesizes in the human body protein and fortifies yang, may eat may also make the shredded coconut stuffing, the cream, the coconut shell may burn makes the activated charcoal; The coconut tree root boils water may treat the inflammation; But "the coconut tree mat "as early as in the Han Dynasty was royal government's high quality goods, more than 2000 year ago Han Dynasty:"Qiongzhou multi-coconut tree seed leaf, past when Seoul emperor, Zhao Feiyan stands, the base younger sister gathers the person to offer Zhu Zhenzhong to have the coconut tree mat, sees again in the world."

椰子具有很多用途：椰子水富含蛋白质、脂肪和多种维生素，促进细胞再生长，可以饮用，甘甜解暑，叶肉含35.5%的脂肪和大量能醒酒、有助于人体蛋白质合成和壮阳的锌，可吃也可做椰蓉、奶油，椰壳可烧做活性炭；椰根煮水可治疗炎症；而&椰席&早在汉代就是朝廷的贡品了，2000多年前的汉朝：&琼州多椰子叶，昔在汉城帝时，赵飞燕立为后，基妹合徒献诸珍中有椰子席，见重于世。&

According to mistuned blade design for the asymmetry stator, the wake force on rotor changed from single frequency and higher amplitude to multi-frequency and lower amplitude.
