Final answer:
To grow Mongo seeds in water, you must first sterilize them, germinate between moist filter papers, transplant into sterile sand, and maintain under greenhouse conditions. Some houseplants, like coleus and money plant, can also be propagated in water through stem cuttings.
Step-by-step explanation:
To grow Mongo seeds in water, start by surface sterilizing the seeds with a sodium hypochlorite solution to prevent bacterial and fungal contamination. After sterilization, rinse the seeds with sterile water.
Place the seeds between moist filter papers in a dark environment to encourage germination.
Water the filter papers with sterile water twice a day until the seeds germinate. Once germinated, transfer the seedlings to containers filled with a sterile growing medium such as river bottom sand that has been washed and autoclaved.
Protect the seedlings from dust and insects using a nylon net and maintain them in a greenhouse. Monitor the moisture and environment to ensure optimal growth conditions.
If needed, inoculate with specific nematodes or other microorganisms for research purposes. Finally, undertake careful management of irrigation, temperature, photoperiod, and photosynthetically active radiation (PAR).
For comparison, plants like coleus and money plant can be propagated in water using stem cuttings. Certain plant cuttings can develop roots when placed in water, a method also applicable to leaves of certain plants like the African violet, which will root when left in water undisturbed for a few weeks.
