“…This trend was also observed in seedless avocados, which were consistently smaller than their seeded counterparts [38]. Similarly, the seedless mutant of 'Hongjiangcheng' sweet orange was smaller than its seedy control [39]. However, in contrast, larger fruit size, including both vertical and horizontal diameters, as well as single fruit weight, were exhibited in this trial by MT in comparison to WT.…”

Seedless is a highly valued commercial characteristic in the citrus industry, both for fresh consumption and for processed markets. In this study, the ‘Succari Sweet Orange’ (WT) and its seedless mutant ‘Juxiangyuan’ (MT), which originated from a bud mutation, were selected to study the formation of a citrus seedless phenotype. Microscopic analysis of MT’s floral organs, including anther and ovary cross-sections, provides insights into its seedless phenotype compared to the original seeded cultivar. Additionally, pollen features, viability, and in vitro germination were examined to determine the cause of seedlessness. MT exhibited significant developmental deformities in both male and female gametes, with pollen grain analysis indicating a high rate of deformity (41.48%), low viability (9.59%), and minimal in vitro germination (9.56%). Hybridization experiments were conducted to assess male and female sterility and pollen incompatibility. Both WT and MT exhibited parthenocarpic development. Notably, MT fruit produced with an average of 3.51 seeds pollinated to WT, despite severe pollen abortion of MT. MT, however, produced seedless fruit through self-breeding or cross-breeding with other varieties, demonstrating stable female sterility. Despite reduced pollen quantity and viability in the seedless mutant ‘Juxiangyuan’, its seedlessness primarily stems from female sterility. This study contributed to a deeper understanding of seedless formation in ‘Juxiangyuan’ and provided valuable information relevant to its commercial cultivation.

Soilless culture also known as water based culture and substrate based culture has immense potential to grow tissue cultured plants in a closed and controlled environment system. This review analyzes the various factors that affect the vegetative growth, reproductive growth, metabolic processes, and gene regulatory functions of tissue cultured plants and the suitability of soilless culture for tissue culture plants. Experiments show that morphological and reproductive abnormalities are mitigated in tissue cultured plants by gene regulation in a closed and controlled environment system. Various factors of a soilless culture influence gene regulation and enhance cellular, molecular, and biochemical processes and compensate constraints in tissue cultured plants in closed and controlled environment conditions. The soilless culture can be utilized to harden and grow tissue culture plants. The tissue cultured plants counter water logging problems and are supplied with nutrients at 7 day intervals in the water based culture. It is necessary to analyze the involvement of regulatory genes in detail in combating challenges of tissue cultured plants in soilless cultures under closed systems. Detailed studies are also required to determine anatomy, genesis, and function of microtuber cells in tissue cultured plants.
