Flowering Hormone - There is increasing evidence to suggest that a flowering hormone exists in plants. This is has been supported by a number of grafting experiments. A short day plant kept in long day conditions can be induced to flower, if a properly photo ..

In the plant Mirabilis jalapa, commonly called as four'o clock plant, the inheritance of flower colour is an example for incomplete dominance. The plant produces two types of flowers red coloured and white coloured. This condition is an example for a pair of contrastin..

According to Mendel, the genotype is made of certain structures called factors. The factors controlled the inheritance of all traits. These factors are present in pairs. The factors are now called genes. Thus the physical basis of heredity are the genes or factors. The different expressions o..

Photoperiodism - W. W. Garner and H. A. Allards work on Maryland Mammoth, a variety of tobacco and Glycine max established the fact that it was the length of the day, which controlled flowering in these plants. Garner and Allard suggested the term photoperiodism to designate the response ..

Light - The effect of light on growth can be studied under 3 headings light intensity, light quality and duration of light. Growth is generally favoured by darkness, but light is indispensable because of its role in the manufacture of food. Young plants growing in the absence of light develop elong..

f r . Mangrove plants exhibit vivipary. Flowering is under the control of daily length of light (photo period) and temperature. Depending upon the photoperiodic responses, 3 categories of plants exist namely SDP, LDP, and day neutral plants. Flowering is a phytochrom..

Physical Basis of Heredity - According to Mendel, the genotype is made of certain structures called factors. The factors controlled the inheritance of all traits. These factors are present in pairs. The factors are now called genes. Thus the physical basis of heredity are the genes or factors. The ..

It is a positive interspecific interaction in which members of two different species favour the growth and survival each other and their association is obligatory. Both the partners are benefitted by this interaction and it is a short or life long association as a means of obtaining food by one or..
