| Experiment Title | Effect of epicotyl thinning and spray of GA3 on growth of polyembryonic mango genotypes | ||
| Research Type | Departmental Research | ||
| Experiment Background | In case of polyembryonic mango, multiple embryos (nucellar and zygotic types) germinate and thereby multiple seedlings takes place at initial growth stages. Due to this, seed germination and vigour is low and subsequent growth of the seedlings slowed down for longer period of time. Therefore, seedlings took longer duration of time to grow compared with monoembryonic mango types. Competition for space, nutrients and water in root region is also one of the reasons. There are possibilities to improve growth of the seedlings through thinning of excess epicotyl after certain period of polyembryonic stone germination. Research work on effect of thinning of excess epicotyl on growth of polyembryonic mango seedlings is lacking and not experimented earlier in case of raising of polyembryonic rootstocks. Spray of gibberellic acid on polyembryonic mango seedlings during initial stages of growth can stimulate the growth. Therefore, the experiment is proposed to shorten the time period for raising polyembryonic seedling rootstocks. | ||
