2 AgrosteminNatural plant nutrient which influences the regulation of growth of cultures in metabolic processes with allelopathic chemical effect in order to increase yield and to improve the quality of fruit.
3 Effect of Agrostemin Activation of biochemical processes which is a consequence of lack of life factorsis a consequence of decreased quantityvolume of substances inside the plant
4 Structure of Agrostemin Active complex: a) amino acids,b) organic acids and c) derivatives of organic acidsInhibitor complexa) derivatives ABA (apcisine acids), b) saturated aliphatic carbon hydrogen and c) cyclic inhibitor (C8H29N3O7)

6 Bioregulating effectAgrostemin encourages plant to optimize its own life processes:a) growth, b) development, c) breeding
7 Biostimulating effect Agrostemin encourages plant to optimize its metabolic processes and to increase the following:qualitative characteristics of culturesquantitative characteristics of cultures,

9 Application Three applications (in fruit growing): before blossom g/ha,during blossom g/ha,after blossom g/haT h i s i s t h e m o s t c o m m o n w a y ! ! !
10 This is how the champions of the fruit ApplicationFive applications (in fruit growing):before blossom – 350 g/ha,during blossom – 300 g/ha,after blossom – 350 g/ha,fruit in ripen pheno phase – 300 g/ha,fruit ripening – 300 g/haThis is how the champions of the fruitrowing industry do!

13 The solution to the problem is in POLLEN The significance of pollen – pollination of plantsThe pollen seeds are created before opening of budsThe creation of pollen can be influenced by the following:internal andexternal factors
14 The formation of pollen seeds Internal factors depend on the plant’sgenetics which determines the following:the size andthe quantity of pollen seedsExternal factors:insufficient soil moisture,exaggerated relative air humidity,lower temperatures by night.
15 Pollen = Flower powdery substance The structure of pollen:Membrane of pollen seedEGZINA – external membrane composed of celluloseor cutinesed by contents of colored substancesINTINA – internal membrane, very thin and in twolayers, composed of cellulose or of pectic substanceswith sporopollenin (high molecule terpen)

18 Germination of pollenGermination of pollen occurs when INTINA (internal membrane) grows through pores of EGZINE (external membrane) creating -THE POLLEN TUBE which goes down to the seed embryo and embryo sac where the swollen pollen seed settles down due to the absorption of liquid from pistil stigma!!!
19 Germination of pollen II Several pollen seeds arrive to pistil stigmaGermination of pollen is effected by the following factors:biotic andabioticFor example: It is due to extremely high temperatures and low relative air humidity,or, on the other side, low temperatures and high air humidity thatpollen quickly loses its germination ability and seeds become stickyand die; even scientific farming methods, such as pruning and manyother similar situations can jeopardize normal plant functionsthis is why it is necessary to use AGROSTEMIN
20 Fertilization and AGROSTEMIN Improvement of germination and fertility of pollen by complex of amino acids which:a) have an inhibitory effect on recessive alleles,b) have a cumulative effect on loci withdominant aleli andc) have an epistatic effect on mutual relationsof dominant genes.
21 AGROSTEMINNow you know why it is necessary to use initially Agrostemin before blossom and how and why to use it further during vegetation of your plants!M.Sc. Engineer Saša AVRAMOVIC
