                                                                   PRUNING

Definition:

                Pruning refers to the removal of plants parts such as buds, developed shoots and roots to maintain a desirable form by controlling the direction and amount of growth.


Objective of pruning:

  • To remove surplus branches.
  • To open the trees so that the fruits will colour more satisfactorily.
  • To train it to some desired form.
  • To remove the dead and diseased limbs.
  • To remove the water sprouts.
  • To improve fruiting wood and to regulate production of floral or buds.

Methods of pruning:

THINNING OUT:

                A few shoots or branches that are considered undesirable are removed entirely without leaving any stub. This operation is known as ‘thinning out’.

HEADING BACK:

  • The removal of terminal portion of the shoots, branches, or limb, leaving its basal portion intact, is called ‘heading back’.
  • Thinning out involving large limbs as in old and diseased trees is called ‘bulk pruning’.
  • These operations are carried out to divert a part of the plant energy from one part to another.
  •  As trees grow older, they should receive relatively more of thinning out and less of heading back. Heading back tends to make trees more compact than thinning out.
  •  If a few of the several branches growing close together on the same parent limb are entirely removed or thinned out, the rest of the branches would grow more vigorously.
  •  Thinning out results in lesser new shoot growth but more new spurs and fruit bud formation than corresponding severe heading back.

    1

    It concerns from primarily

    It affects functions only

    2

    It determines plants outline, its branching and frame work.

    Assists more in what the tree does in respect to fruiting

    3

    Generally concerned with first few years of the tree growth to determine its annual frame work.

    Annually done

Allelic Interactions - dominant and recessive alleles, codominant alleles, lethal alleles, penetrance or expressivity, multiple alleles

                                                ALLELIC RELATIONSHIP   Dominant and Recessive Alleles:   Whenever one of a pair of alleles can come to phenotypic expression only in a homozygous genotype, we call that allele a recessive factor. The allele which can phenotypically express itself in the heterozygote as well as in the homozygote is called a dominant factor. Upper- and lower-case letters are commonly used to designate dominant and recessive alleles respectively. Usually, the genetic symbol corresponds to the first letter in the name of the abnormal (or mutant) trait.   (a) Carriers:   Recessive alleles (such as the one for albinism) are often deleterious to those who possess them in duplicate (homozygous recessive genotype). A heterozygote may appear just as normal as th...

                                                                                       APOMIXIS   The normal sexual cycle (amphimixis) involves two important processes (a) Meiosis, this transforms a diploid sporophytic cell (megaspore mother cell, MMC) into four haploid gametophytic cells, and (b) Fertilization, In which two haploid gametes of opposite sex fuse re-establishing the diploid sporophytic generation. Thus, in a sexual cycle a diploid generation (sporophytic) alternates with a haploid generation (gametophytic) In angiosperms the gametophytic generations are very short and are represented by embryo sac on the female side and microspores or pollen grains on the male side. In some plants meiosis and syngamy are int...

Cytokinin and their role

                                                                                            Cytokinin Discovery: The presence of cell division inducing substances in plants was first demonstrated by Haberlandt in 1913 in Coconut milk (liquid endosperm of coconut) which contains cell division inducing substances. In 1954, Skoog and Miller discovered that autoclaved DNA from herring sperm stimulated cell division in tobacco pith cells. They called this cell division inducing principle as kinetin (chemical structure: 6-Furfuryl Amino Acid). This does not occur in plants. In 1963, Lethan introduced the term cytokinin. In 1964, Lethan and Miller isolated and identified a new cytokinin called Zeatin from unripe grains ...
