The Way

The shape of the leaf blade of each lobe is progressively settled in. First, the midvein separates two lateral areas with equivalent mitotic potentialities. In each of these lateral areas, these potentialities, which at first are evenly spread out, are then concentrated only in the basal part, which will be referred to as the leaf blade generative center. Great regulation potentialities are maintained in these centers throughout their duration, i.e., over three plastochrons. Cellular clusters, which will progressively differentiate and correlatively lose their abilities to regulate, arise from generative centers toward an apical direction. The evenness of the lamina edge is linked with the wholeness of the generative centers. Any subdivision of any one of these centers will generate a lobule, which, in turn, will behave as a miniature lobe. The subdivision occurs as a result of cutting but can also be achieved by application of exogenous cytokinin. The physiological and biochemical mediums of mitotic potentialities are still to be found. It is the same for the way the cytokinins act. Key words: cassava, leaf blade, morphogenesis, cytokinin.

Undisputed molecular evidence for apomixis in cassava is presented. Based on genome sampling with 130 RAPD markers we confirmed apomixis for one offspring of a cassava clone derived from an interspecific hybrid. The probability that complete uniformity in RAPD fingerprints between mother and offspring occurred by chance was < 10−5.

Abstract. Introduction: Cassava Manihot esculenta (Crantz) is a perennial shrub native to South America that is an essential source of carbohydrates for more than 600 million people in tropical countries. Objective: The aim of this study was to describe and compare the leaf blade anatomy of ten genotypes of cassava. Methods: The methodology for anatomical descriptions was processed and 30 leaves of each of the varieties were included and sectioned according to paraffin impregnation protocols. Results: The results showed that the leaf blade anatomical structure of all the varieties in general terms show differences. All varieties had monostratified epidermis, leaf mesophyll consisted of a palisade parenchyma in a single layer and multiple layers of spongy parenchyma. Polyphenolic idioblasts were observed immersed in the palisade parenchyma and spongy parenchyma. Between 3-7 xylem ribs with their respective phloem were found in the midrib in almost all varieties. Trichomes were only found in two varieties (NAT31-ECU72) and leaves were all hipostomatic. Conclusions: The results reveal that NAT31 is the material with the most anatomically marked differences (i.e. presence of trichomes, papillary cell, and, on the adaxial face, special provision in the arrangement of stomata and epicuticle wax patterns), characteristics that might be related to pest resistance.

<p>Agricultural by-product, especially from cassava plants, can be found easily at all over Indonesia. Parts of cassava (Manihot esculenta Crantz) plant that can be used for animal feed are leaves, stem covering, tuber (in dry or<br />wet condition, with or without skin). Cassava leaves cannot be used freely as animal feed, because of the persistence of anti-quality, i.e. Cyanide Acid (HCN) and tannin substance. Cassava leaves can be found easily in the dry season, when<br />generally the presence of forage as ruminant’s diet is so limited. This research had to be done to observe potency of cassava leaves as supplement for Bligon goat’s diet. This research used 24 mature early pregnant Bligon goats. The<br />goat divided into 3 treatments, those are : K as Control Diet (conventional diet which usually be given by the farmers); T1 or Treatment 1 (Control Diet+300 g cassava leaves); and T2 or Treatment 2 (Control Diet+260 g cassava<br />leaves+200 dried cassava tuber). The result showed that cassava leaves supplementation increased EE and TDN consumption. From total consumption, cassava leaves and dried cassava tuber increased DM, OM, CP, EE, and TDN<br />digestibility, but reduced CF digestibility. The effect of anti-coccidia didn’t appear optimally which shown by there was no significant differences of the amount of coccidian oocyste in the goat feces. However, the amount of coccidian<br />oocyste in the feces reduced (1666.67 on the T1 and 2500 on the T2) as compare to those on the K (5000).</p><p>(Key words: Bligon Goat, Cassava leaves, Feed Supplement, Coccidiostat)<br /><br /></p>

An interspecific hybrid between cassava, Manihot esculenta Crantz, and M. neusana Nassar and the backcrossed progenies was examined meiotically and mitotically. The F1 hybrid showed irregular meiosis due to unpaired chromosomes. The backcrossed progeny ranged in fertility from 17.7 to 35.8%. Meiotic restitution was also observed in all of the hybrids. Diploid pollen formation also occurred and ranged from 0.6 to 1.6%. Irregular meiosis among the F1 hybrid produced aneuploidy in backcrossed progeny. When the F1 hybrid was used as the maternal plant in backcrosses with cassava, this improved seed setting in the BC1 progenies, whereas the reciprocal backcross produced sterile progenies. Key words: Wild species, meiotic restitution, aneuploidy, diploid gamete

Job (Ayyūb) is a byword for patience in the Islamic tradition, notwithstanding only six Qur'anic verses are devoted to him, four in Ṣād (vv.41-4), and two in al-Anbiyā' (vv.83-4), and he is mentioned on only two other occasions, in al-Ancām (v.84) and al-Nisā' (v.163). In relation to the space devoted to him, he could be accounted a ‘lesser’ prophet, nevertheless his significance in the Qur'an is unambiguous. The impact he makes is achieved in a number of ways. One is through the elaborate intertext transmitted from the Companions and Followers, and recorded in the exegetic tradition. Another is the way in which his role and charisma are highlighted by the prophets in whose company he is presented, and the shifting emphases of each of the sūras in which he appears. Yet another is the wider context created by these sūras in which key words and phrases actualize a complex network of echoes and resonances that elicit internal and transsūra associations focusing attention on him from various perspectives. The effectiveness of this presentation of him derives from the linguistic genius of the Qur'an which by this means triggers a vivid encounter with aspects of the rhythm of divine revelation no less direct than that of visual iconography in the Western Tradition.

O trabalho teve por objetivo verificar diferenças entre rendimento do concentrado proteico e proteína bruta da folha da mandioca (Manihot esculenta Crantz), obtidos a partir de três variedades comerciais: branca, cascuda e vermelha. As manivas foram plantadas seguindo o delineamento experimental inteiramente casualizado com três repetições. Nas comparações entre as variedades, considerou coletas escalonadas pós-plantio, realizadas aos 12, 14 e 16 meses. O concentrado proteico foi obtido a partir da farinha das folhas inteiras e submetido ao método de termo - coagulação ácido e a proteína bruta pelo método padrão AOAC. Os dados foram submetidos a análise de variância e comparados pelo teste de Tukey - 5% de probabilidade. Os resultados não indicaram diferença significativa entre as médias obtidas para rendimento de concentrado proteico. Para a variável porcentagem de proteína bruta a variedade Branca foi a que apresentou maior valor, com média de 46,25%, seguida pela Cascuda e Vermelha, 44,52% e 37,30%, sucessivamente. Conclui-se que outros estudos devem avaliar condições que possam influenciar no teor de proteína foliar, como clima e solo, e, avaliar os níveis de ácido cianídrico de cada variedade, indicando qual das três é a melhor para a extração do concentrado proteico das folhas. Palavras chaves: Manihot esculenta Crantz, variedades comerciais, concentrado proteico, proteína bruta. ABSTRACT: The study aimed to assess the differences between income protein concentrate, crude protein of cassava leaf (Manihot esculenta Crantz), obtained from three commercial varieties: white, red and cascuda. The cuttings were planted following the completely randomized design with three replications. Comparisons between the varieties considered after planting staggered collections, held on 12, 14 and 16 months. The protein concentrate was obtained from flour of whole sheets and subjected to the term method - acid coagulation and crude protein by AOAC standard method. The data were submitted to ANOVA and Tukey test - 5% probability. The results indicated no significant difference between the mean values obtained for protein concentrate income. For the variable percentage of crude protein White variety showed the highest, with an average of 46.25%, followed by cascuda and Red, 44.52% and 37.30%, successively. We conclude that further studies should evaluate conditions that may affect the leaf protein content, such as climate and soil, and evaluate the hydrocyanic acid levels of each variety, indicating which of the three is the best for the extraction of protein concentrate from leaves Key words: Manihot esculenta Crantz, commercial varieties, protein concentrate, crude protein.

In Linguistics the terms model and modelling have a vast array of meanings, which depends on the purpose and the object, and the type of the scientific research. The article is dedicated to the investigation of a special procedure of semantic processes modelling, deducing and substantiating the notion “evolutional semantic model”, the content and operational opportunities of which differ drastically from the essence and purpose of the known from the scientific literature phenomenon of the same name. In the proposed research this variety of modelling is oriented towards the description of the dynamics of the legal terms content loading, the estimation of possible vectors of the semantic evolution on the way of its terminalization/determinalization. The evolutional model of semantics has here as its basis the succession of sememes or series of sememes, the order of which is determined with accounting of a number of parameters. The typical schemes of the meaning development, illustrated by the succession of sememes, are considered to be the models of semantic laws (evolutional semantic models = EMS). Their function is the explanation of the mechanism and the order of the stages of the semantic evolution of the system of the words which sprung from one root on the way of its legal specialization, and, therefore, the proposed in the paper experience of semantic laws modelling differs from the expertise of the “catalogue of semantic derivations”, proposed by H. A. Zaliznjak, which doesn’t have as its purpose the explanation of meaning displacements, and from the notion of semantic derivation, models of derivation, dynamic models, worked out by O. V. Paducheva, which also only state such a displacement, without proving its reality. Key words: evolutional semantic model (EMS), modelling, semantic law, sememe, pre(law).
