Leaf Color Chart (LCC) for Fertilizer N Management in Rice A standardized leaf color chart for assessing leaf N status. The leaf color chart (LCC) is an easy-to-use and inexpensive diagnostic tool for monitoring the relative greenness of a rice leaf as an indicator of the plant N status (Alam et al. 2005).
May 14, 2019· Developmental transitions during shoot development in plants are regulated by factors originating outside and within the shoot apical meristem (SAM). The best-known example of this is the vegetative-to-reproductive transition, which is initiated by a leaf-derived signal that transforms the vegetative SAM into a developmentally stable inflorescence meristem.
