Abstract

Banana Bunchy Top Disease (BBTD) caused by Banana Bunchy Top Virus (BBTV) is one of the most serious banana diseases, constraint and devastate to the local and regional banana production. Some of banana cultivars were more readily infected by the virus, but considering no cultivars is resistant. The incidences of BBTD and the type and severity symptoms in natural conditions without any artificial inoculation were recorded. The observations results on 2009 showed that 12.14% of the total accessions indicated positively infected BBTD. The BBTD incidences were increased rapidly about twofolds per year, 28.57% in October 2011 and 54.29% in October 2011. The spread and development of BBTD is optimum at humid, high rainfall intensity and temperatures, high soil fertility and also low light intensity or shaded. The latest monitoring on February 2012 (62.14%) comprises of 64 accessions were positively infected and 39 accessions were symptomless. Those symptomless accessions were initially indicated as tolerant banana cultivars to BBTD e.g. Pisang Kepok (BBB), Pisang Sobo (BBB), Pisang Bandung (ABB), Pisang Nangka (AAB), Pisang Candi (AAB) and  Pisang Raja Marto (AAB). These preliminary results are in agreement with several previous studies indicated that genotypes with one or two B genomes tend to be more tolerant to BBTD. However several cultivars which known tend to BBTD tolerant are indicated susceptible to Blood Disease. Some cultivars also showing complication symptoms both BBTD and Blood Disease.

Abstract

Plant species of Annonaceae family were collected in Purwodadi Botanic Garden (PBG) needs ex-situ conservation efforts to prevent threat of extinction. Annonaceae plants collection in PBG have experienced dynamics over the past of 12 years which affect to diversity and conservation efforts. This study aimed to determine the dynamics or development of Annonaceae plants collection in PBG for the past of 12 years and how their conservation efforts. The methods were used are primary and secondary data collections from Registration Unit, measurement of stem diameter, plant height, branch-free stem height (BFS) of Annonaceae plants collection and microclimatic data (temperature, humidity, soil pH and light intensity) in each block of Annonaceae plants collection. Data were analyzed descriptively and by Principal Component Analysis using the statistical program PAST 4.0. The Annonaceae plant collections in PBG have fluctuated in the number of plants, genera, species, specimens and unidentified species with the addition of 28, 10, 6, 58, and 7 plants respectively. There were also 81 times of species identity changes. Annonaceae plant collections in PBG was able to well adapt and develop based on the average of stem diameter and BFS, with humidity and light intensity became the most influential environmental factors for plant growth. The management of Annonaceae plant collections in PBG consisted of the maintenance activities and studies to support the conservation. By regulating and manipulating of humidity and light intensity in Annonaceae plant collections, plant growth will increase and well maintenance. Management efforts can be planned and developed properly by knowing the dynamics of plant collections.
