MORFOLOGI BUNGA YANG SESUAI BAGI KULTUR MIKROSPORA PADA TANAMAN JARAK PAGAR (Jatropha curcas L.)

Abstract

An experiment aimed in gaining information on morphological characteristics of Jatropha curcas (L.) containing high frequency of uninucleate microspores has been done. This was important due to the successful application of experiment in haploid technique through anther or microspore culture is strongly determined by the availability of information from basic research such as appropriate morphology of the flowers. This scientific article, in our knowledge, was an early explanation of the initial steps of whole procedures in the microspore culture of Jatropha curcas (L.). Results of the research showed that the morphological features of flower that contained high frequency of mid- and late uninucleate microspores was that the flowers must be in the range of 2 to 3 mm in length. Such flowers contained yellowish anthers.Key words: Flowers length, mid- and late-uninucleate, morphology, physic nut, microspore

Analysis of Human Performance and Potential Application of Virtual Reality (VR) Shooting Games as a Shooting Training Simulator for Military Personnel

“…Figure 2 shows the learning curve of shooting in terms of shooting accuracy and precision. According to Pritasari, et al (2013) and Suaib (2011), repeated-measures ANOVA can analyze a research variable that is observed repeatedly at different times or periods. Based on the results (Table 2), there was a significant increase in the accuracy of regular shooters [F (4.44) = 11.253; p = 0.000] and expert shooters [F (4.44) = 18.738; p = 0.000].…”
