Boron promotes the translocation of sugars and cell development and is believed to be important for growth regulators (table 2). Boron is not mobile in plants. Consequently, B deficiency symptoms most often appear on the growing tip of the plant.

Depending on the species of bacteria and the tissue infected they produce and release enzymes that degrade cell walls, growth regulators that alter the plants normal growth, toxins that degrade cell membranes and complex sugars that plug water conducting tissue.

kea.kar.nic.inReproductive growth- After the vegetative growth, plants produce flowers which is the reproductive part of the plant. This is called reproductive growth/phase. 15.2- Growth curve – It is an ‘S’ shaped curve obtained when we plot growth against time (Fig. 15.2). It is also called ‘sigmoid ‘curve.This curve mainly shows four phases

Good response in cuttings can be obtained by over night dipping in 100-200 ppm IBA. 2000 to 5000 ppm of indolebutyric acid (IBA), indoleacetic acid (IAA) and nephtalenacetic acid (NAA) through quick dip methods are the most successful growth regulators.

www.agrimoon.comPlant pathology can also be defined as the study of the nature, cause and prevention of plant diseases. Plant pathology is related to most of the old and new sciences like biology, physics, chemistry, physiology, mathematics, genetics, soil science, biochemistry, biotechnology etc. Plant pathology has the following major objectives. 1.
