Golden rice is new genetically modified rice variety (Oryza sativa). It is produced to biosynthesize beta-carotene for the synthesis of vitamin A. It is rich in vitamin A content. It was created by Peter Beyer. It is intended to produce a fortified food to be grown and consumed in areas with a shortage of dietary vitamin A.

Huifluefuntus respiration tate duing itpenting of the tration is called respiratory climactic. the whe while oth in pineapples. It also induces flowering in mango. Since ethylene regultates so many physiological processes, It is one of the most widely used PGR in agriculture. The most widely used plants ethephon. Ethephon in an aqueous solution is readily absorbed and transported within the plant and releases ethylene slowly. Ethephon oxposure hastens fruit ripening in tomatoes and apples and accelerates abscission in flowers and fruits (thinning of cotton, cherry, walnut). It promotes femak flowers in cucumbers thereby increasing the yield. 15.4.3.5 Abscisic acid As mentioned earlier, abscisic acid (ABA) was discovered for its role in regulating abscission and dormancy. But like other PGRs, It also has other wide ranging effects on plant growth and development. It acts as a general plant growth inhibitor and an inhibitor of plant metabolism. ABA inhibits seed germination. ABA stimulates the closure of stomata and increases the tolerance of plants to various kinds of stresses. Therefore, it is also called the stress hormone. ABA plays an important role in seed development. maturation and dormancy. By inducing dormancy, helps seeds to withstand desiccation and other factors unfavourable for growth. In most situations. acts as an antagonist to GAs. We may summarise that for any and every phase of growth. differentiation and development of plants, one or the other PGR has some role to play. Such roles could be complimentary or antagonistic. Thesc could be individualistic or synergistic.
