(3) Beneficent
(4) Sufficient
The elements which are actively mobilizable within the plant body and are exported to young developing plant parts, their deficiency symptom will be first observed in
1. Both in young and old parts
2. Only in young parts
3. First in old parts
4. First in young parts
The deficiency symptoms of mobilizable substances appear first in Older parts because
(1) In order to mobilize the elements to young part, the biomolecules of older parts are broken down
(2) In order to mobilize the elements the older part becomes weaker
(3) The work of mobilization is random and takes a lot of energy to cause it
(4) All of these
The elements which are not actively mobilizable or immobilized within the plants . The deficiency is symptom is observed in
(1) Both in young and old parts
(2) Only in young parts
(3) First in old parts
(4) First in young parts
The deficiency symptoms of how many elements will be appearing in older tissue first?
N,K,Mg,S,Ca
(1) Zero
(2) Three
(3) Two
(4) Four
The deficiency symptoms of S and Ca will appear first in
(1) Both in young and old parts
(2) Only in young parts
(3) First in old parts
(4) First in young parts
Why does S and Ca deficiency not found in older parts first?
(1) As they are immobilizable
(2) As they are very abundant in older parts
(3) As newer parts are already deficient
(4) Both A and B
The knowledge of deficiency symptoms of mobilizable and immobilizable substances actually helps in
(1) Horticulture
(2) Agriculture
(3) Both A and B
(4) Pisciculture
Chlorosis is not
(1) Loss of chlorophyll
(2) Leading to yellowing of leaves
(3) Deficiency of elements N, K, Mg, S, Fe, Mn, Zn and Mo
(4) Accumulation of mutated chlorophyll
