This research aims to study the appropriate growing media for the growth of cacti that can reduce production costs and promote cacti’s growth. The research used four genera of cacti, i.e., Gymnocalycium, Astrophytum, Mammillaria, and Echinopsis, which were famous in the commercial market in Thailand. The experimental design was completely randomized designs (CRD) with four different growing media and three replications; T1) fermented rain tree leaves (FRTL): perlite: vermiculite: pumice: vermicompost as a control, T2) FRTL: rice husk: coconut coir: charcoal: vermicompost, T3) FRTL: rice husk ash: coconut husks chips: expanded clay: vermicompost and T4) rice husk ash: vermicompost. The plant was cultivated the plastic pot 2-inches and collected the growth for six months. The result showed that Mammillaria was planted in Treatment 3 gave the greatest stem diameter and the number of roots. A similar increase in stem diameter of Echinopsis and Gymnocalycium had the newest areoles. While planted in T4, as a result, the genus Astrophytum has increased in stem diameter, the number of new areoles, and the number of roots. In the Gymnocalycium also found an increase in stem diameter. Therefore, the use of cacti growing media in T3 as an appropriate for the growth of cacti. Furthermore, it can reduce the production cost of growing media about 0.72 baht per pot (33%) when compared with the commercial media (T1) in a 2-inches plastic pot.

The Impact of Different Colors of Light-Emitting Diodes on Cacti Germination and Seedling Growth

To identify suitable light colors to break seed dormancy and enhance the growth of cactus seedlings. A short photoperiod and less light intensity affect seedlings, resulting in low germination and slow growth. Four cacti species are A. asterias, E. grusonii, M. geometrizans, and T. alonsoi, commonly grown as ornamental plants. The completely randomized design was experimental. The plant was cultured under the five different colors of light-emitting diodes (LEDs): natural light (NL), red, blue, green, and white LED, providing light for 12 hours/day. The results found that all cactus seeds can absorb water and have more than 50% viability, except for E. grusonii. The seed germination (%G) increased in NL and various colors of LED. White LED had the highest %G in A. asterias, but green LED had the highest α-amylase activity. In E. grusonii, M. geometrizans, and T. alonsoi, %G and α-amylase activity were the highest under red LED. In addition, all four cacti species had the lowest mean germination time under red LED. The growth of A. asterias and M. geometrizans had the highest seedling vigor, stem diameter, plant height, and root length under NL. They had the highest chlorophyll a and chlorophyll b. In E. grusonii and T. alonsoi under NL, with the highest stem diameter, plant height and increases chlorophyll a and chlorophyll b. However, white light has the maximum root length and seedling vigor. Thus, red, green, and white LEDs effectively break seed dormancy, while white LEDs stimulate cactus growth as the natural light.

The aim of this study was to investigate methods for breaking the seed dormancy of cacti that are cultivated in Thailand. To stimulate seed germination and decrease the production time for cacti, the research used four cacti species: Astrophytum asterias, Echinocactus grusonii, Myrtillocactus geometrizans, and Turbinicarpus alonsoi, which are extensively grown as ornamental cacti species in Thailand. The experimental design used in this study was a completely randomized design (CRD). The pot experiment consisted of 4 dormancy breaking methods and six replicates, 30 seeds per pot. For the control, seeds were sown onto planting media directly. In the experimental samples, seeds were subjected to different pre-soaking treatments: soaking for 24 h in room temperature water (28±2<sup>o</sup>C), GA<inf>3</inf> 500 ppm for 24 h, and H<inf>2</inf>SO<inf>4</inf> (50%) for 30 min. The seed germination and plant growth data were collected after sowing cacti seeds for two months. The results showed that soaking cacti seeds in room temperature water produced the highest germination rates for A. asterias, E. grusonii, and M. geometrizans. In addition, this treatment also reduced the production time of M. geometrizans. Concurrently, A. asterias, E. grusonii, and M. geometrizans presented higher stem diameters and root lengths of the seedlings, as well as the best result on the seedling vigor of cacti. Soaking seeds with GA<inf>3</inf> resulted in the highest germination percentage of T. alonsoi and accelerated seed germination of A. Asterias, and T. alonsoi. Moreover, this treatment led to the maximum root lengths and seedling vigor of T. alonsoi. However, soaking seeds with H2SO4 was a treatment that gave E. grusonii the maximum root length and seedling vigor.
