李白《清平调词》新解——从“叶想衣裳花想容”说起

李白的<清平调词>三首,第一句"云想衣裳花想容",北宋蔡襄书"云想"作"叶想".然未为人所注意.清人王琦认为是蔡氏落笔之误.另外,对于三首诗的本义,历来的解释都以为是咏人.本文从"叶想"非误的观点出发,重新论定三诗的本义为咏花之词.咏花为主,暗寓咏人.纠正古今说诗者对此诗本义的整体位移性的误解.     

牡丹变芍药

花鸟虫草,凡是能被人养着的,不必说它珍贵,即使不漂亮,你也会夸它超凡脱俗,具有野性美。正因为这一点,我看见那盆"大牡丹"——叶子十分绿,根有些黄的植物时,觉得是一盆牡丹,它开起花来又大又红,花瓣一层一层的,可好看了。这也让我联想到春天、生命,似乎还有什么别的,说不清。"怎么?想买这盆花?"我耳边传来一句话,抬头一看,原来是店主,只见他一脸黝黑的皮肤,衣服上沾着一些泥土,脸上还挂着一丝微     

牡丹不高兴

我不是没见过牡丹,所谓国色天香,所谓花之富贵者,曾不止一次耳闻目睹。可煞有介事专程赴异地赏花,却是第一次。谷雨过三天,园里看牡丹。一般说,民谚总是近似真理,汇集着千百年的智慧。然而这一年,这一句却有点信口雌黄的意思,被事实胜于雄辩地推翻。我是在谷雨一周后到古县的,风尘仆仆赶到这并不了解的地方,只为一睹天下第一牡丹的芳容,然而最终这次赏花之旅不得不加上一个遗憾的定语——未遂。气候没按常理出牌,本该是暮春却     

土壤地球化学特性对凤丹皮品质的影响

为了探明土壤地球化学特性对凤丹皮质量的影响,对铜陵市凤凰山矿区中丹皮的重金属和主要药用成分进行研究分析。研究结果表明：尾矿库附近采样区(PP)土壤中Cu、Pb、Cd和Zn的含量分别是国家土壤环境质量标准(GB15618—2018)中农田土壤风险筛选值的8.88、4.06、1.17和2.36倍,污染较为严重;除Cd外,凤丹皮中Cu、Zn、Pb、Mn的生物累积量差异显著(P<0.05);在3处采样区中,PP处丹皮样品中Cu、Zn和Pb含量均高于其它两处对照采样区,且Cu超标,成为影响丹皮质量的主要因素;丹皮中的药用成分丹皮酚和芍药苷含量均与土壤中重金属Pb、Cd和Zn含量表现出极显著的负相关关系(pa<0.01)。研究说明矿业活动产生的土壤重金属污染对药用植物凤丹的质量造成了一定影响。     

芍药属的研究(1)——国产几个野生种核型的报道

In the present paper 8 species with 15 populations of the genus Paeonia L. (if P. papaveracea and P. japonica are recognised as species) were collected from Sichuan, Shaanxi and Hebei provinces (see the Appendix for detail of the materials).  The micrographs of their somatic metaphase (also Mii in the case of P.veitchii) are shown in Plates 1-4, the karyo- type formulae, ranges of chromosome length and classification of karyotypes according to Steb- bins (1971) are shown in Table 5: the idiograms in Figs. 1-2, and the parameters of chromo- somes in Table 1-4.  The essential points are mentioned as follows:        (1)   Chromosomes of the various species in the section Modan have so far been examined and they are all diploid, the two species in the section Onaepia are also diploid, and thus tetraploids exist only in the section Paeonia.        (2)  Chromosomes in the genus Paeonia are relatively stable except for the differentiation of ploidy.  The karyotypes (Table 1-4) show no differences among different taxa in Sect. Modan and the same can also be said about the taxa in Sect. Paeonia (Table 1).  Not only are the karyotypes very similar, but also among the members within  either section have the same parameters of chromosomes, and, differences, if occur, are not statistically significant. Between the two sections, however, the situation is different. The arm ratios of the first pairs of chromosomes in Sect. Modan are 1.53, 1.52 and 1.48 (Table 1), but those in Sect. Paeonia are 1.12-1.28 (Table 2-4), 95% confidence limits are 1.46-1.60 for the section Modan and 1.07-1.28 (1.21-1.35 only for PB85078) for the section Paeonia, not overlapping, which indi- cates that the two sections have differentiated in respect of the first pairs of chromosomes.        (3)The population PB85024, which belongs to the P. obovata complex, has a karyotype of 2B (stebbins, 1971), which is a new one in the genus Paeonia. This karyotype is a stable one, for several individuals in the population are uniform in this respect, which shows that Steb- bins’ (1971) generalization that all the species in Paeonia have 2A does not hold true.        (4)  Three populations of P. obovata complex studied in this work from Sichuan and Shaanxi are all tetraploids, and one from Hebei is a diploid.  From the present work and the previcus reports, the materials from Japan and Korea, no matter whether flowers are pink or white, are diploids, those from Heilongjiang Province (with both pink and white flowers) (Liu Ming-yuan, personal communication) and from Heibei Province (with pink flowers) in China are also diploids, the one from Sakhalin (pink flowers) is tetraploid, those from Priamur of the Soviet Union are a tetraploid (with white flowers) and a diploid (with pink flowers), and those from Shaanxi (the Qinling Range) and western Sichuan (with both pink and white flowers) are all tetraploids.  As far as we have now known, ploidy in this parti- cular complex is correlated with the geographical distribution: diploids are found in the cen- tral part, tetraploids occur in the northern limits, and in the south  letraploids are the only cytotype.      (5)  The materials of P. mairei from western Sichuan and Shaanxi (the Qinling Range) are found all to be tetraploids, which shows that two cytotypes, diploid and tetraploid, exist in this  species,  but the geographical distribution pattern of these two cytotypes is to be revealed in the future investigation.
