The morphogenetic property of cytokinin was first experimentally proved by:
1 Hannig
2 Guha and Maheshwari
3 Skoog and Mille
4 Went
Explanation:
C The morphogenetic property of cytokinin was first experimentally proved by 'Skoog and Miller'. Cytokinins control aspects of almost all plant growth and development process. They are a class of plant hormones that promote cell division in plant roots.

Who proposed the histogen theory
1 Nageli
2 Schmidt
3 Strasburger
4 Hanstein
Explanation:
D The 'Histogen Theory' proposed by 'Hanstein' (1870) and supported by Strasburger (1868). This theory explain three principal tissue of root i.e. vascular cylinder, cortex and epidermis originate different groups of initial, cells or histogen in apical meristem-plerome, problem and dermatogens respectively.

Grafting involved the formation of a young plant :
1 with the root of scion and shoot of stalk
2 with the root of stalk and shoot of scion
3 by stem cutting
4 by layering
Explanation:
B Grafting involved the formation of a young plant with the root of stalk and shoot of scion. Grafting or graftage is a horticultural technique where by tissues of plants are joined so as to continue their growth together.

Etiolation in plants is caused when
1 they are grown in dark
2 they have mineral deficiency
3 they are grown in intense light
4 they are grown in blue light
Explanation:
A Etiolation is a process which is characterized by long, weak stems, smaller leaves due to longer internodes and a pale yellow colour. It is caused when the plants grow in dark without or little light.
