Twenty-one genotypes (six parental lines and 15 direct crosses) of butternut squash (Curcurbita argyrosperma subsp. sororia) were evaluated at the Experimental Center of the Universidad Nacional de Colombia in Candelaria (Valle del Cauca, Colombia) during the second semesters of 2012 (2012B) and the first semester of 2013 (2013A). Heterotic effects (average, variety, and specific) were determined for ether extract production per plant (EEPP) and the following components: percentage ether extract (EE) in seed, seed weight per fruit (SWF), 100-seed weight (100- SW), and number of fruits per plant (NFP). The methodology of Gardner and Eberhart (1966) was used in a randomized complete block experiment design with four replicates (five plants per replicate). Variety heterosis accounted for 48% of the variation of total heterosis for EEPP. Variety heterosis was better expressed in 2013 first semester, with significant differences for EEPP, SWF, and 100-SW; average heterosis was significant for EEPP and EE. In 2012 second semester, heterosis was significant for SWF, indicating genetic divergence between hybrids and parents. Introductions 256 and 132 expressed the greatest effects of variety heterosis for EEPP and superior segregants should be selected from these two parental lines. No significant differences were observed on specific heterosis; however, the best hybrid in terms of EEPP at 2013 first semester came from crosses 256×132 and 140×260.

Grafting as a technique is gaining attention, and the production and demand for grafted vegetable plants have increased worldwide, especially for greenhouse cultivation. This study aimed to evaluate the potential of different scion × rootstock combinations or improving the yield of the tomato crop under greenhouse conditions. For this purpose, a scion of tomato cv. Libertador was grafted on two commercial tomato rootstock (‘Olimpo’ and ‘Armada’) and cultivated in a greenhouse in a randomized complete block experiment design, with four scion-rootstock combinations: vigor and resistance rootstocks, self-grafting and non-grafted plants. The yield and yield components were evaluated (number and weight of the fruits of extra, commercial, and non-commercial quality, weight per cluster, and weight per fruit).  Although vigor rootstocks produce less fresh fruit in the first harvests, from the seventh harvest onwards, the vigor rootstocks outperformed the other treatments in the accumulated yield by producing 37, 22 and 22% more yield, and 60, 30 and 40% higher number of fruits of extra quality in the resistance rootstock, self-grafted, and non-grafted plants. The fruits plants of vigor rootstock, self-grafted and non-grafted above 150 g, tend to have a cylindrical shape; however, fruits in the resistance rootstock tend to be flattened. The use of a vigor rootstock increased the yield of cv. Libertador, regarding the rootstock with resistance characteristics and controls, self-grafted, and non-grafted plants.

<p class="JurnalASSETSABSTRAK">ABSTRAK</p><p>Pengampunan pajak telah dilakukan berulang kali di Indonesia yaitu 1964, 1989, 2008 dan 2016. Penelitian ini menguji apakah ada perbedaan kepatuhan pajak antara yang mengetahui pengampunan pajak berulang serta merasakan kepastian penegakan hukum dan yang tidak. Penelitian ini menggunakan  quasi eksperimen faktorial 2 x 2 antarsubyek dengan mahasiswa akuntansi di FEB yang sedang mengambil matakuliah manajemen pajak sebagai partisipan. Hasil dari penelitian ini adalah terdapat pengaruh antara pengetahuan tentang pengampunan pajak berulang maupun kepastian penegakan hukum terhadap kepatuhan pajak. Hasil dari pengujian interaksi yang diperoleh adalah ketika wajib pajak tidak mengetahui adanya pengampunan pajak yang berulang dan merasakan kepastian penegakan hukum yang tinggi akan menghasilkan kepatuhan yang paling tinggi. Sebaliknya ketika wajib pajak mengetahui adanya pengampunan pajak yang berulang dan tidak merasakan kepastian penegakan hukum yang tinggi akan menghasilkan kepatuhan yang rendah.<em></em></p><p class="JurnalASSETSABSTRAK"><em>ABSTRACT</em></p><p><em>Tax amnesty has been repeadly implemented in Indonesia namely 1964,1989, 2008 and 2016.The purpose of the study is to examine is there any tax compliance differences between those who perceive recurring tax amnesty and feel legal certainty and to those who do not. This quasi experiment design was consisted of 2x2 between subject factorial design, with Bachelor’s Degree of Accountancy at FEB UKSW who took Taxation Management as participants. The result shown that there is influence between recurring tax amnesty knowledge and legal certainty in the tax compliance. The result of the interaction testing shown that when taxpayer are not aware of any recurring tax amnesty and feel the high legal certainty will result high compliance. Conversely, when taxpayers know that there is recurring tax amnesty and do not sense a high level certainty, it would result a low tax compliance.<br /></em></p>
