Richmond lang effect is related to. What is the Richmond Lang Effect? The Richmond Lang effect is primarily caused by cytokinins, a class of plant hormones that play a crucial role in regulating plant growth, development, and physiology. It is named after the researchers, Richmond and Lang, who first studied this effect. Richmond and Lang found that cytokinin plays a crucial role in delaying senescence in Richmond and Lang (1957) first showed that cytokinin treatment leads to greater retention of chlorophyll and protein in excised leaves of cocklebur plants (Xanthium pennsylvanicum). These hormones are known to delay the process of senescence in plants. The regulator acts by retarding the rate of destruction of chlorophyll and yellowing of leaves. Understanding the Richmond-Lang Effect: The Richmond-Lang effect refers to the phenomenon discovered by scientists Richmond and Lang in 1967, which is related to the role of a specific plant growth regulator (PGR). - Cytokinins are one of the five most important Plant Growth Regulators (PGRs). 7 This cytokinin effect has since been shown in many other species, even resulting in re-greening of yellowing leaves. Cytokinins are called Anti-ageing hormones as most of their effects on plants delay ageing and promote growth, directly or indirectly. Jul 4, 2010 · The Richmond Lang effect refers to the phenomenon of rapid stem elongation and growth observed in plants. **Understanding the Richmond-Lang Effect**: The Richmond-Lang effect refers to the phenomenon discovered by scientists Richmond and Lang in 1967, which is related to the role of a specific plant growth regulator (PGR). This phenomenon, known as the Richmond-Lang effect, prolongs the aging process for many days. 🌿 Ever wondered how plants can defy aging and keep their leaves vibrant for longer? Dive into the fascinating world of the Richmond-Lang effect and cytokini The Richmond-Lang effect is related to cytokinins. Richmond and Lang were two scientists who, in 1967, discovered that the cytokinin hormone helps in delaying senescence (aging) in plants. 2. Delay of senescence (The Richmond-Lang Effect): Richmond and Lang (1957) demonstrated that senescence in detached leaves of Xanthium can be significantly delayed by kinetin treatment. 8 Experimentation has led to the Step by Step answer for “Richmond-Lang effect is related to” of Biology Class 11th. Get FREE solutions to all questions from chapter PLANT GROWTH AND DEVELOPMENT. Which one is the physiological role of cytokinin? Promotion of cell division: The major physiological role of naturally occurring cytokinins is to promote cell division. Richmond and Lang discovered this effect in 1967. In the presence of CytokininsCytos cell Kinesis to divide are a class of plant growth regulators PGRs which primarily promotecell division in plantsThey arebasic purinederivative hormones majorly synthesized in the root apices of the plants and transported to the other partsThe first cytokininwas discovered in 1954bySkoog and Miller In 1967 scientists Richmond . **Identifying the PGR**: The PGR in question is cytokinin. Richmond Lang effect is the retardation of aging due to the application of the plant regulator cytokinins. **Step-by-Step Solution:** 1. k4q vrp 0qq me tea gixve m5370pw 9juaqji7 ef4x5q vcqfwl
