Abstract

This study aimed to evaluate the effects of the dosage and application frequency of chicken bone meal on the growth of water spinach (Ipomoea reptans L.). The experiment employed a factorial design within a completely randomized design (CRD) consisting of two factors, namely chicken bone meal dosage and application frequency. The observed parameters included plant height, number of leaves, and plant dry weight. The results showed that both the dosage and application frequency of chicken bone meal significantly affected the growth of water spinach. A dosage of 60 g produced the highest dry weight, reaching 20.76 g, compared with 6.10 g in the control treatment, while an application frequency of once per week resulted in better plant growth. The interaction effect indicated that the A3B1 combination produced the best growth performance, with dry weight reaching 24.97 g. Therefore, the application of chicken bone meal at an appropriate dosage and frequency can optimize the growth of water spinach.

Abstract

Light and temperature are major environmental factors that shape plant growth and development through interconnected signaling networks. Photomorphogenesis is regulated by photoreceptors, whereas thermomorphogenesis represents developmental adjustment to elevated ambient temperature. This narrative literature review synthesized peer-reviewed studies published from 2002 to 2025 and retrieved from PubMed, ScienceDirect, SpringerLink, Wiley Online Library, Nature, MDPI, Frontiers, and Google Scholar based on their relevance to photoreceptor-mediated light and temperature signaling. The review compares the roles of phytochrome, cryptochrome, phototropin, and UVR8 in photomorphogenesis, thermomorphogenesis, and thermosensing. Available evidence identifies phytochrome, particularly PhyB, as the best-established direct thermosensor, whereas cryptochrome modulates temperature-responsive growth through PIF4. Phototropin conveys temperature information through the lifetime of its photoactivated LOV state in specific physiological responses, while UVR8 acts predominantly as a negative regulator of thermomorphogenesis. Crosstalk among these photoreceptors converges on PIFs, COP1/SPA, HY5, ELF3, and auxin-related pathways. This integrated signaling framework coordinates developmental plasticity, stress acclimation, and vegetative and reproductive performance under fluctuating environments.
