Abstract:

Buddleja saligna Willd. is an evergreen tree native to South Africa. Historically, the tree has been used for the treatment of various diseases and has been scientifically found to have promising pharmacological effects. In the current study, the phenological growth stages of B. saligna are characterised according to the Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie (BBCH) scale standardised coding. A total of eight out of ten principal growth stages have been described for the development of buds, leaves and shoots, inflorescence emergence, flowering, the development and ripening of fruits, and senescence. A total of thirty-three secondary growth stages were identified and described in detail. Illustrative images with codification have been provided to better define and describe the growth stages. The temperature fluctuations during the study period could have influenced the flowering time, as phenological shifts were observed during the study period. These data are a useful reference for efficient management, cultivation, and scientific research.

Meristems and Plant Growth

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Biological Clocks and Seasonal Responses

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Morphogenesis

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Bacterial Growth Curve

Bacterial Growth Curve

The bacterial growth curve is a fundamental concept in microbiology that describes the dynamics of bacterial population growth in a closed system with controlled environmental conditions, such as temperature and nutrient availability. This curve is divided into four distinct phases: lag, log (exponential), stationary, and death phases, each reflecting a unique stage of bacterial adaptation and growth. During the lag phase, bacteria acclimate to their surroundings by synthesizing essential...

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Introduction to Seed Plants

Introduction to Seed Plants

Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms.
