Fungsi nutrient asid amino baja foliar taaveekun

  1. 1. BAJA FOLIAR TAAVEEKUNBAJA FOLIAR TAAVEEKUN
  2. 2.   PENGGALAK PERTUMBUHANPENGGALAK PERTUMBUHAN• Kerap kali tanaman gagal menghasilkan buah yang optimum walaupun mendapat bekalan nutrient yang betul. Kurang keberkesanan  fisiologi tumbuhan adalah punca kepada fenomena ini.• Penggalak pertumbuhan pokok adalah bahan yang digunakan untuk mengatur pengambilan nutrient dan pertumbuhan tanaman. Penggalak pertumbuhan ini memainkan peranan penting dakam percambahan biji benih, meranumkan buah, memperkasa pengambilan nutrient, menyemarak sistesis protin, memperkuat ketahanan dan membantu keadaan runtunan, mengurangkan keguguran bunga dan buah dan membantu tumbesaran pokok. • Biasanya pengatur pertumbuhan pokok ialah auxins, gibberellins, ethylene etc.. Permintaan kepada pilihan semulajadi sudah bertambah. 
  3. 3. Kesan Amino Acid Terhadap PokokKesan Amino Acid Terhadap Pokok• Keperluan Asid Amino dalam kuantiti secukupnya telah diketahui lama bagi kaedah untuk menambahkan hasil dan kualiti tanaman keseluruhannya. • Amino Acid dibekalkan kepada pokok melalui serapan tanah. Ia membantu microflora didalam tanah, lantas menggalakan integrasi penyerapan nutrient.• Amino Acid membantu pertambahan kepekatan klorofil yang membawa kepada kesan fotosintesis yang lebih sempurna. Ini akan menjadikan tanaman lebih hijau pekat.
  4. 4. Kesan Asid Amino Kepada Tanaman• Penggunaan Amino acid dalam kuantiti yang betul adalah kaedahuntuk menambah hasil tanaman dan kualiti pokok. Sugguhpun pokokmempunyai kemampuan asas melakukan biosintesis bagimenghasilkan asid amino yang diperlukan dari nitrogen, carbon,oxygen and hydrogen, proses biokimia ini sangat komplek danmemerlukan tenaga yang banyak.• Dari itu, penggunaan amino asid seperti dari TaaVeeKun Supermembolehkan tumbuhan menjimatkan tenaga untuk proses ini,dimana boleh didedikasikan untuk pertumbuhan yang lebih sempurnasemasa tahap pertumbuhan kritikal.• Amino asid adalah ramuan asas dalam proses biosintesis protin danhampir 20 jenis asid amino terlibat dalan proses biosintesis ini. Kajianmendapati asid amino boleh secara terus atau separa terlibat dalamaktiviti fisiologi tumbuhan.• Amino acid yang dibekalkan dalam bentuk cecair, menyerap kedalamstomata tumbuhan atau melalui kawasan akar bila bercampurdengan tanah. Ini akan turut meningkatkan micro flora, yang akanmembantu penyatu serapan nutrient.
  5. 5. Sifat Semulajadi AuxinsSifat Semulajadi Auxins• Auxin adalah berasal dari perkataan auxien Greek bermaksudtumbuh. Campuran kompoun akan dikelaskan sebagai auxins jika iabersifat menyebabkan pemanjangan sel mata pucuk pokok ataupunberupa asid indoleacetic dalam aktiviti fisiologi.• Auxins biasanya menyebabkan kesan sampingan selain daripemanjangan sel mata pucuk tetapi karektor ini dianggap kritikalkepada semua auxins dan membantu pengistilahan hormone.
  6. 6. Functions of AuxinFunctions of Auxin•The following are some of the responses that auxin is known to cause (Davies, 1995; Mauseth, 1991; Raven, 1992;Salisbury and Ross, 1992).• Stimulates cell elongation• Stimulates cell division in the cambium and, in combination with cytokinins in tissue culture• Stimulates differentiation of phloem and xylem• Stimulates root initiation on stem cuttings and lateral root development in tissue culture• Mediates the tropistic response of bending in response to gravity and light• The auxin supply from the apical bud suppresses growth of lateral buds• Delays leaf senescence• Can inhibit or promote (via ethylene stimulation) leaf and fruit abscission• Can induce fruit setting and growth in some plants• Involved in assimilate movement toward auxin possibly by an effect on phloem transport• Delays fruit ripening• Promotes flowering in Bromeliads• Stimulates growth of flower parts• Promotes (via ethylene production) femaleness in dioecious flowers• Stimulates the production of ethylene at high concentrations
  7. 7. Nature of CytokininsNature of Cytokinins• Cytokinins are compounds with a structure resemblingadenine which promote cell division and have othersimilar functions to kinetin. Kinetin was the first cytokinindiscovered and so named because of the compoundsability to promote cytokinesis (cell division). Though it isa natural compound, It is not made in plants, and istherefore usually considered a "synthetic" cytokinin(meaning that the hormone is synthesized somewhereother than in a plant). The most common form ofnaturally occurring cytokinin in plants today is calledzeatin which was isolated from corn (Zea mays).
  8. 8. Cytokinin FunctionsCytokinin FunctionsA list of some of the known physiological effects caused by cytokinins are listed below.The response will vary depending on the type of cytokinin and plant species (Davies,1995; Mauseth, 1991; Raven, 1992; Salisbury and Ross, 1992).•Stimulates cell division.•Stimulates morphogenesis (shoot initiation/bud formation) in tissue culture.•Stimulates the growth of lateral buds-release of apical dominance.•Stimulates leaf expansion resulting from cell enlargement.•May enhance stomatal opening in some species.•Promotes the conversion of etioplasts into chloroplasts via stimulation of chlorophyllsynthesis.
  9. 9. The Nature of GibberellinsThe Nature of Gibberellins• Unlike the classification of auxins which are classified onthe basis of function, gibberellins are classified on thebasis of structure as well as function. All gibberellins arederived from the ent-gibberellane skeleton. The structureof this skeleton derivative along with the structure of afew of the active gibberellins are shown above. Thegibberellins are named GA1....GAn in order of discovery.Gibberellic acid, which was the first gibberellin to bestructurally characterised , is GA3. There are currently136 GAs identified from plants, fungi and bacteria
  10. 10. Functions of GibberellinsFunctions of Gibberellins• Active gibberellins show many physiological effects, each depending on the type ofgibberellin present as well as the species of plant. Some of the physiologicalprocesses stimulated by gibberellins are outlined below (Davies, 1995; Mauseth,1991; Raven, 1992; Salisbury and Ross, 1992).• Stimulate stem elongation by stimulating cell division and elongation.• Stimulates bolting/flowering in response to long days.• Breaks seed dormancy in some plants which require stratification or light to inducegermination.• Stimulates enzyme production (a-amylase) in germinating cereal grains formobilization of seed reserves.• Induces maleness in dioecious flowers (sex expression).• Can cause parthenocarpic (seedless) fruit development.• Can delay senescence in leaves and citrus fruits.
