Factors Affecting Root Formation of Phaseolus Vulgaris.
The successful rootingof leafy cuttings inivolves three physiologieally distinct processes: initiation of root primordia; development of true roots from these initials; and mainitenance of the cutting as ani excised organ during the rooting. The first of these, where it does niot take place sponitanieously, cani be brought about in many plants by treatment with auxini. The second (outgrow^th of...
متن کاملThe loss of morphogenetic potential and induction of phenylalanine ammonia-lyase in suspension cultures of Phaseolus vulgaris.
The loss of morphogenetic potential in bean suspension cultures has been investigated by measuring the amounts of phenylalanine ammonia-lyase activity induced in the cells when they are transferred from a medium in which they are grown and maintained to an induction medium. The tissue has been grown in 2 types of medium: (1) supplemented with 2,4-dichlorophenoxyacetic acid as the only growth ho...
متن کاملCytokinin Oxidase from Phaseolus vulgaris Callus Cultures : Affinity for Concanavalin.
Cytokinin oxidase activity from Phaseolus vulgaris cv Great Northern callus cultures exhibited affinity for the lectin concanavalin A. Over 80% of the activity extracted from the callus tissue bound to a concanavalin A-Sepharose 4B column. The bound activity was eluted from the column by the addition of methylmannose to the eluting buffer. On the basis of this result, it appears that most of th...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولInduction of cytokinin autonomy by N,N'-diphenylurea in tissue cultures of Phaseolus lunatus L.
The ability of N,N'-diphenylurea (Ph(2)urea) to substitute for cytokinin-active adenine derivatives in promoting callus growth of Phaseolus lunatus has been examined. In general, Ph(2)urea stimulated callus growth at high concentrations, although the growth of most callus tissues was irregular. Variability in the sensitivity and uniformity of the growth response to Ph(2)urea was found among dif...
