Abstract

Identification of Phytophthora Isolates from Coconut Origin Wite Amplification Fragment Length Polymorphic (AFLP)Coconut Bud rot and nutfall caused by  fungus are the major anddangerous diseases of coconut palm. Nutfall of nuts and death of the palms leading to the reduction of coconut production are some of the consequences of the diseases. Morphologically identification of the causal agents is very limited and need certain skill. Molecular analysis is a good method to accurately identify characterize the disease causing pathogens especially Phytophthora originated from coconut palm. AFLP is one the accurate reproducible methods providing uniformnity results. The research aimed to identify and characterize Phytophthora isolate causing but rot a nutfall diseases. A total of 14 isolates was tested by its AFLP and then by AFLP with specific primers. The identification results showed that the 14 tested isolates with ITS1/ITS4 had band profile on the size of 900 base pairs (bp) which is a specific band profile for P. Palmivora. Of the 16 combinations specific primer of AFLP, indicated primers eg E, H, and Q gave accurate and homolog results that is good for AFLP analysis. AFLP analyses for 14 isolates of  gave accurate results of the band diversity.

Abstract

Female Flowers and Fruits Setting Characteristic of Hybrids CoconutDwarf x DwarfThis study purpose to determine the performance of Dwarf x Dwarf coconut. The experiment was conducted from July 2009 until August 2010, at the Experimental Garden of Mapanget and Paniki, and at the Laboratory of Plant Breeding, Indonesian Coconut and Palmae Research Institute (ICOPRI), Manado. Treatment consists of crosses between Dwarf coconut types, namely Raja Dwarf (GRA), Bali Yellow Dwarf (GKB) and Salak Dwarf (GSK), and their resiprokal, (1) GRA x GKB, (2) GRA x GSK, (3) GKB x GRA, (4) GKB x GSK, (5) GSK x GRA dan (6) GSK x GKB. Each type of crossing it uses as many as 15 coconut trees as replicates, and each tree is used 3 bunches as examples of female parents. Parameters were observed in female parents are: Number of female flowers per bunch, number of fruit setting the age of 3 , 6 and 9 months per bunch, and number of fruit harvested (age 11 months) per bunch. Morphological data of leaf, stem, female flowers, and ripe fruit of the three female parents also observed prior to hybridization. Data analysis used Complete Random Design of ANOVA, and continued with t Tests. Research result showed that the Salak Dwarf coconut varieties (GSK), the female flowers produce more than the palm varieties Raja Dwarf (GRA) and the Bali Yellow Dwarf (GKB). The potential of hybrid coconut to produce fruit setting is so most GSK x GRA, and followed by GSK x GKB, ie. 12,90 fruits and 10,81 fruits. The highest fruit yields are obtained in crosses between GSK x GRA, which is 12.90 fruit/bunch.

Abstract

The Rainfall Interception of Different Age of CoconutDistribution of the amount of water available in coconut plantation determined not only by supply from outside in the form of rain or irrigation, but also is determined by planting distance, planting system and age of coconut. Some researches indicates a significant correlation between the rainfall intensity and the agronomic properties of plants with the amount of trough fall, net or effective rainfall and canopy interception. Therefore, the distribution of rain in coconut palms in different ages need to be studied. The main objective of this research is to know the difference of trough fall, effective rainfall and rainfall interception in of coconut palms in different ages. The research was done observation methode the coconut palms were selected purposively based on the coconut ages (5, 20 and 50 years old). For measuring the rainfall distribution at each coconut plantation used from coconut palms.The results showed that the average trough fall of 5, 20, and 50 years old coconut palms was 53.67, 31.14, and 39.21 percent of average rainfall, respectively. Effective rainfall or net rainfall that reached the area in coconut plantations did not differ with trough fall. The average rainfall interception of canopy 5, 20, and 50 years old were coconut plantation was are respectively 46.33, 68.82, and 23.51 percent of rainfall. The relationship during rainfall intensity and trough fall and effective rainfall is positive linear. Its meaning that the higher rainfall intensity will followed by the greater of trough fall and the effective rainfall.In the otherside, the In the other side the relations between rainfall intensity and canopy interception is logarithmic. At means that each canopy in different age of coconut have a certain capacity to hold rain water. Capacity of coconut canopy 5, 20, and 50 years old to hold water of rain were 1.171 , 2.219, and 0.896 mm respectively.

Abstract

Status of Brontispa longissima (Gestro) Pest on Coconut Plantationin Biak Numfor District, Papua ProvinsiB. longissima (Coleoptera : Chrysomelidae) originated from Aru Island and Papua has damaged and caused loss of coconut production in Indonesia and Asia Pasific regions. A research to generate information on the status of this pest such as pest and natural enemies population and damage level was conducted in June 2010 in Biak District, Papua Province. A total of nine villages of three sub districts in Biak District, Papua Province were surveyed and Brontispa-attacked coconut palms were purposively observed. Damage level was assesed from four fully opened young coconut leaflets. Damage level in Samofa Subdistrict (42,63%) and East Biak (33,73) was higher than that in North Biak (22.12%). It was relating with the pest population per palm in each district where the highest pest population was found in Samofa sub district, followed by East Biak and the lowest in North Biak. Reduction of coconut production wasestimated to 40 – 60%. Two natural enemies identified were (Hymenoptera: Eulophidae) and predator earwig (Dermaptera).
