The research was aimed to study flowering biology, fruit and seed development to identify parthenocarpic lines derived from somatic hybridization. The research was carried out at Pacet Experimental Station of ICABIOGRAD, Cianjur, West Java (1150 m asl), during August 2019-July 2020. The research materials were 15 citrus lines derived from somatic hybridization between Mandarin Satsuma and Siam Madu, of which 5 plants (± 2 years old) per line were prepared. Observation was carried out on flowering phenology, flower morphology, fruit development, pollen viability, and stigma receptivity. Seedless fruits from un-pollinated, selfpollinated, and cross-pollinated flowers of each line were investigated. The results showed that flower morphology of the 15 citrus lines varied in the number of petals, flower diameter, pistil length relative to the stamen, and number of stamen. The development from bud emergence to fruit ripening also varied among and within lines, ranging from 212 to 316 days. Among the lines, FS 25 showed a stronger character towards stimulative parthenocarpy. FS 84 and FS 89 were potential sources of pollen (pollenizer) to produce seedless fruits.","PeriodicalId":44658,"journal":{"name":"Agrivita","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46799283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data are compared to the standard of maximum residue levels (MRL) of pesticides in agricultural products. Results show that residual pesticides in treated soils are below the detection limit of the GC equipment, except malathion is detected with values ranging from 0.039-0.050 ppm. However, residual organophosphate pesticides in the bulbs are mainly below the maximum residue levels. The only exception is chlorpyrifos which has a value above the maximum residue levels of pesticides (0.076 ppm).

A total of 60 felled trees of A. mangium were used to develop a volume equation by measuring the volume at four different classes of elevation. The study of stand volume estimation in Malaysian plantations, particularly in Bintulu, is sparse. To get the average cross-sectional area, the volume of each tree in each part of the felled trees was estimated using Smalian’s and Newton’s formulas. Four equations were developed in this study to predict the volume from the diameter and analyze the effect of elevation on tree volume. According to the regression analysis, there was a significant relationship between the volume and diameter for each slope steepness. The Very Slope site had the highest volume with an R² value of 0.948 for the model’s fit, which revealed that 94.8% of the data could be evaded. Volume estimation using the regression model can be used to determine and categorize according to its class of elevation, and there is an effect of elevation on standing volume.
