Answer 1

${ { \underline{ \underline{ \purple{ \huge{vegetative \: propagation}}}}}}$




▪ Formation of new plant from vegetative part of plant like root , stem and leaf is known as vegetative propagation.




${ \sf{ \underline{ \blue{two \: methods \: of \: vegetative \: propagation}}}}$



natural method

artificial method








${ \star{ \tt{ \red{ \underline{ \underline{ \: \: artificial \: method}}}}}}$
( by human )




${ \sf{a){ \pink{ \: cutting}}}}$


▪ In this, cutting part .i. e., root/ stem/ leaf is dipped in Auxin to iniate root formation then planted in soil.


${ \sf{stem \: cutting{ \blue{ - sugarcane, \: rhizome}}}} \\ { \sf{leaf \: cutting{ \blue{ - bryophyllum}}}} \\ { \sf{root \: cutting{ \blue{ - guava}}}}$





${ \sf{b){ \pink{ \: \: layering}}}}$


▪ In this, adventitious root development is induced in branch which is still attached with parent plant. Afterwards , planted in soil.




${ \sf{c){ \pink{ \: \: grafting}}}}$



▪ It is the technique of connecting two different plant to make a single composite plant .


✒ Only in dicot plant , having Cambium and Eustele.


✒ Occur in closely related plant.



✒ Part of plant which develop in root system
STOCK


✒ Part of plant which develop in shoot system SCION






${ \sf{ d){ \pink{ \: \: \: micropropagation}}}}$

${ \blue{ \sf{(clonal \: propagation)}}}$



▪ Propagation by tissue culture

▪ Clone produce, require less time, less raw material, less place

▪ environment stress free

▪ virus free plant can produce.
