Effect of various treatments on breaking seed dormancy and germination enhancement in Custard apple (Annona reticulata L). Local cultivar

Abstract

Custard apple (Annona squamosa L.) is a very sweet delicate flesh in the human diet for ages due to its nutritional and medicinal values; it is a deciduous or semi-deciduous tall woody shrub. The effect of various treatment on breaking seed dormancy and germination enhancement in (Annona squamosa L) Local. Natural regeneration by seeds is poor due to seed dormancy. To overcome poor germination problem cultivar was study carried out at, the experiment was laid out in Randomized Block Design with seven treatments and thrice replicated, organic substance like are Coconut water @ 50%, Urea @ (0.1%), Hot Water @, Cold Water @, Cow urine @ (10%), Cow dung slurry @ (10%) and Control (Distilled water) in 24 hours socking. Amongst the different treatments, the seed soaked in coconut water are maximum observation germination percentage (69.483%), however, minimum days required for germination (31.14 days), Height of seedling (cm) 19.04, Diameter of the stem 2.09, Number of leaves per seedling 18.52, and Leaf area (cm2) 90 DAS respectively, was observed under treatment T1. The present investigation concluded that the better seed germination and growth of custard apple seedling was observed in treatment T1 Coconut water @ 50% for 24 hours is desirable.
