孩子眼中的科学知识——读《胡椒生长在哪里？》

胡椒生长在哪里？说实话，这是一个不明确的问题：因而在这本图画书的封面上，就罗列了五种由孩子给出的不同回答：在装胡椒的袋子里；在胡椒点心房；在辣的地方；在很远的地方；在胡椒种植园里。这是孩子们的有趣回答，但很显然，这不是作者要给出的答案。     

山胡椒属系统的研究

 This paper is an attempt to discuss the relationship and phylogeny within the genus Lindera, based upon on analysis of shortened brachlets, on which the inflorescences are inserted, and other morphological characters. The shortened branchlets are metamorphic shoots which are often at the transitional stage between branchles and inflorescences. The advanced shortened branchlets usually with an undeveloped terminal bud, posses scale-like leaves, and the inflore- scences so formed are sessile and aggregate.  In primitive taxa, such as Lindera nacusua (Don) Merr., L. gracilipes H. W. Li and L. tanchuanensis Feng et H. S. Kung, the branchlet is usually not shortened, with well-developed terminal bud, forming a single axillary pseudo-umbel, while its peducle is usually very slender and stamens of pistillate flower sometimes more or less deve- loped.  The leaves on the upper part of branchlet are normal and the lower part of branchlet becoming bracteal,  In the genus the development of shortened branchlets (Fig. 1.) from the ones in the primitive taxa to the ones in the advanced taxa may be found.        Other important morphological characters are the length of peducles.   The peduncle is usually slender in the primitive taxa, short or even sessile in the adanced taxa.        There are two types of venation in the genus: the pinnate and trinerved.  As the primitive group trib. Perseeae Mez shows pinnate veins, pinnate ventation in Lindera is more primitive than trinerved one.        It might be possible that a transition occure in the genus from evergereen habit to deciduous one as shown in Lindera glauca B1., L. angustifolia Cheng and L. praecox B1., whose leaves tar- dily wither but persistent over winter.        The relationships within Lindera are shown in a hypothetical genealogical tree (Fig. 4), which includes the system of Litsea, developed parallelly with Lindera.        From the study of morphological characters, the author infers that both Lindera and Litsea have originated from a common ancestory related to the tribe Cinnamomeae Baill. which has a single axillary inflorescence, with hermaphrodite flowers, 4-locular anthers and penninerved to trinerved leaves.     

有趣的食虫植物——茅膏菜

茅膏菜(Dionaea muscipula)俗称捕虫草、食虫草、地胡椒、地珍珠、一粒金丹、落地珍珠、苍蝇网、山胡椒草等,多年生草本,属五桠果亚纲茅膏菜科茅膏菜属。它们通常生长在酸性很强的沼泽地上,能进行光合作用,但不能合成足够多的含氮化合物,以昆虫为氮源维持生活。1生物学特征株高

饲料卵磷脂对花尾胡椒鲷幼鱼生长的影响

实验采用不同卵磷脂添加量[0，2，4，6，8，10：100（w／w饲料）]的配合饲料投喂花尾胡椒鲷（Plectorhynchus cinctus）幼鱼．对卵磷脂影响幼鱼生长存活的作用机制进行初步研究，投喂10d后，幼鱼体重随着饲料中卵磷脂添加量的增加而增加，而成活率则在添加量为4：100时最高．在添加卵磷脂组中，幼鱼蛋白酶活性基本上随着添加量的增加而增加，对照组的蛋白酶活性则异常地高；脂肪酶活性在卵磷脂添加量为2：100时最高，而后随着添加量的增加而下降；添加组的α-淀粉酶活性比对照组的高．饲料中添加卵磷脂可显著提高花尾胡椒鲷幼鱼Ca^2＋-ATPase和鳃Na^＋、K^＋-ATPase酶活性，且卵磷脂含量为2：100时Ca^2＋-ATPase和Na^＋、K^＋-ATPase活性最高．从结果看出，花尾胡椒鲷幼鱼的成活与Ca^2＋-ATPase和鳃Na^＋，K^＋-ATPase活性有关．生长与消化酶，尤其是蛋白酶活性有关。
