Streszczenie Badano wpływ form rodzicielskich na cechy owoców duriana z zapyleń krzyżowych. Odmianami rodzicielskimi użytymi w krzyżowaniach były ‘Matahari’, ‘Kani’, ‘Otong’, ‘Sitokong’, ‘Lai’, ‘Kim’, ‘Sunan’, ‘Bokor’, ‘Hortimart’ i ‘Tangkue’. Badania wykazały, że odsetek zawiązywania owoców wynosił od 0% do 20% w różnych kombinacjach krzyżowań. Wpływ odmiany jako formy matecznej był istotny na takie cechy, jak zawiązywanie owoców, masę owoców, obwód owocu, długość owocu, grubość skórki owocu, grubość miąższu, udział części jadalnej, długość kolców, liczba komór bez miąższu, całkowita masa i liczba nasion w pełni wykształconych oraz procentowy udział nasion niewypełnionych. Odmiana Matahari użyta jako forma mateczna wytwarzała największe owoce z najgrubszym miąższem podskórnym, w najwyższym procencie części jadalnych i wszystkimi komorami wypełnionymi. Formy ojcowskie miały wpływ na zawiązywanie owoców, długość owocu, grubość skórki, liczbę nasion, całkowitą wagę nasion oraz udział nasion niewypełnionych. Odmiana Sitokong użyta jako forma ojcowska miała najniższą całkowitą masę nasion i najmniejszą liczbę nasion oraz najwyższy udział nasion niewypełnionych
Morphological and genetic characterization of tamarind are useful and important for breeding, commercialization and gene bank management. The cultivars characterized in this study were Intapalum, Sritong, Prakaitong, Khantee and Srichompoo. The comparison of five sweet tamarind cultivars were carried out using ANOVA and DMRT with 0.05 of significant levels. The relationship between morphological characteristics was calculated by the Pearson's correlation coefficient. Phylogenetic analysis used NTSYSpc ver. 2.1 to generate a dendrogram of fruit characters. The quantitative characters (pod weight, pod diameter, and pod length) were significantly different. The biggest fruit was Sritong and the smallest was Khantee. Significant differences were shown on two qualitative characters such as pod shape and flesh color, while there were no significant difference on the seed shape, seed color and skin color. There were positive correlations among all quantitative pod characters of the samples. Pod weight was significantly correlated with pod diameter, however pod length and pod diameter were not significantly correlated. The similarity level from five sweet tamarind cultivars was 44-100 %.
Shallot is an important spice and seasoning in Indonesia. It is consumed almost daily in many dishes. The objective of this experiment was to study the effect of the medium and the variety on the yield of shallots grown in a polybag. The experiments were arranged in a two-factorial randomized complete block design with three replications. The factors were medium (1 soil: 1 paddy husk ash and 1 soil: 1 compost) and variety (Agrihorti 1 and Mentes). Data were statistically analyzed by Analysis of Variance (ANOVA), and the means were compared using Honestly Significant Difference (HSD) at P < 0.05. There was no interaction between medium and variety. Overall, all treatments did not significantly affect yield. Varieties were significant differences on bulb diameter; however, they were not significant differences on bulb height, fresh bulb weight per polybag, and bulb number per polybag. Those media are considered as precise media due to they contain organic materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
