“…Furthermore, Figueiredo et al. (2017) found that salt stress caused a higher accumulation of carbohydrates in shoots and roots. The trend of change in both TNC and RSC is expected because they have a source sink relationship as TNC serves as the resource for the increased RSC under increased salinity conditions.…”

“…Figueiredo et al. (2017) indicated there is less information on the behavior of calla lily under salinity conditions. Therefore, our objectives were to evaluate black calla lily salinity tolerance as a way of adaptation, examine the negative effects of salinity on plant morphology, and determine which tolerance mechanisms are related to salinity tolerance.…”

Response to salinity in black calla lily plant under Mediterranean conditions

High soil salinity in arid and semiarid regions results in a reduction in plant growth and productivity. Also, low precipitation is insufficient to cope with high salinity. Black calla lily (Arum palaestinum Boiss.) belongs to Araceae and is used as an ornamental, for food, and in folk medicine. Salinity reduces water and nutrient uptake and causes the accumulation of toxic levels of ions (K and NA) in black calla lily plants. This study was established to evaluate black calla lily salinity tolerance and to determine its tolerance mechanisms. Seedlings of A. palaestinum were transplanted into lysimeter columns. Irrigation treatments included tap water (control) and water with electrical conductivities of 5, 15, and 25 dS m −1 . Treatments were continued for 3 mo. Leaf color, leaf area, and plant height were estimated or measured weekly. Samples were collected for total nonstructural carbohydrates (TNC), proline, reducing sugars content (RSC), and tissue K + and Na + content analyses. Increasing salinity led to a decrease in leaf characters, TNC, chlorophyll content, plant height, and K + /Na + ratio, and an increase in proline content and shoot total RSC. The significant positive association between proline content and salinity suggested that proline can enhance osmotic adjustment and act as a N or C source that helps the processes of stress recovery. Dynamics of TNC and RSC indicated that salinity tolerance is an energy-dependent process. Results indicated that A. palaestinum collected from the Mediterranean area can tolerate irrigation water with a salinity level up to 15 dS m −1 .

“…However, calla lily is sensitive to salinity caused by excessive doses of fertilizers . Calla lily plants under salt stress conditions have reduced plant height, fewer leaves and shoots, and anatomical changes (Figueiredo et al, 2017). Thus, it is important to monitor its nutrient solutions.…”

The soilless cultivation of plants is an alternative for the production of flowers with high quality. Calla lily is normally produced on soil benches, but have shown some limitations as bacterial infections occur. One alternative may be a soilless cultivation. Hence, experiments were conducted with the objective to evaluate the development of calla lily in two types of hydroponic production systems. The semihydroponic system was tested using as substrates or growing media such as, coconut fiber, sand, vermiculite, and phenolic foam sheets. For the other system, ebb-and-flow, the substrates tested were vermiculite, coconut fiber, and expanded clay. Two different nutritional solutions were tested in both systems. in the semihydroponic system. In general, calla lily was adapted and showed a good development in a soilless cultivation. The best initial development of the calla lily was provided using vermiculite and sand as substrates on semihydroponic. And for the ebb-and-flow system, coconut fiber induced better development. As conclusion, hydroponic cultivation systems are efficient for the initial development of calla lily. The recommended substrates are those with lower porosity, such as sand, vermiculite, and coconut fiber.

“…During the growth process, calla lilies are vulnerable to several biotic and abiotic challenges. Previous research has shown that salinity in the soil induced salt stress and affected calla lily development, including a decrease in plant height, leaf number, root length, shoots, and root dry matter ( Figueiredo et al, 2017 ). Additionally, bacterial soft rot deteriorated the bulb quality of calla lily and caused significant economic losses ( Li et al, 2022 ).…”

Establishment of an efficient regeneration and Agrobacterium transformation system in mature embryos of calla lily (Zantedeschia spp.)

Calla lily (Zantedeschia spp.) have great aesthetic value due to their spathe-like appearance and richness of coloration. However, embryonic callus regeneration is absent from its current regeneration mechanism. As a result, constructing an adequate and stable genetic transformation system is hampered, severely hindering breeding efforts. In this research, the callus induction effectiveness of calla lily seed embryos of various maturities was evaluated. The findings indicated that mature seed embryos were more suitable for in vitro regeneration. Using orthogonal design experiments, the primary elements influencing in vitro regeneration, such as plant growth regulators, genotypes, and nanoscale materials, which was emergent uses for in vitro regeneration, were investigated. The findings indicated that MS supplemented with 6-BA 2 mg/L and NAA 0.1 mg/L was the optimal medium for callus induction (CIM); the germination medium (GM) was MS supplemented with 6-BA 2 mg/L NAA 0.2 mg/L and 1 mg/L CNTs, and the rooting medium (RM) was MS supplemented with 6-BA 2 mg/L NAA 0.7 mg/L and 2 mg/L CNTs. This allowed us to verify, in principle, that the Agrobacterium tumefaciens-mediated genetic transformation system operates under optimal circumstances using the GUS reporter gene. Here, we developed a seed embryo-based genetic transformation regeneration system, which set the stage for future attempts to create new calla lily varieties.
