The growth evaluation of two species Annona at seedling phase

摘要

The aim of the research was to evaluate the growth of two Annona species at the seedling phase. The research was conducted at Aripan Experimental Field of Indonesian Tropical Fruit Research Institute and started from February 2007 until August 2008. There were two Annona species as treatment, namely: A.muricata (soursop) and A. Montana (mountain soursop). Each of treatment consisted of 42 seedlings. The growth parameters observed were plant height, stem diameter, root dry weight, dry weight of plant parts which grow above soil surface, and total plant dry weight . T hese parameters were analyzed by t-test 0, 05% . The result showed that the growth of the two Annona species at 6 month s after planting was not significantly different. It showed that there was not significant difference between the two Annona spesies on plant h eight, stem diameter, root dry weight, dry weight of plant parts which grew above soil surface, and total dry weight of plant . Due to this result seedling of A. montana Macf. (mountain soursop) was able to be used as rootstock .
