ABSTRACT<br/> CALVENTAS, MARY JOY L. 2019. Enhancement of the Root and Shoot<br/>Development of Different Varieties of Gumamela (Hibiscus rosa-sinensis)<br/>Cuttings Using Organic Solutions. Undergraduate Thesis. College of Agriculture<br/>Food and Sustainable Development. Mariano Marcos State University, City of Batac.<br/>Ilocos Norte. 69pp.<br/>Adviser: Prof Maura Luisa S. Gabriel<br/> The study on the enhancement of the root and shoot development of the<br/>different varieties of gumamela cuttings using organic solutions was conducted at<br/>Barangay Burayoc, Pagudpud, Ilocos Norte from December 2018 to January 2019.<br/>The study generally aimed to determine the effectiveness of different organic<br/>solutions as growth enhancer during the propagation of different varieties of<br/>gumamela and specifically, it aimed to evaluate the effect of organic solutions in the<br/>root and shoot development of different Gumamela varieties, and identify the best<br/>organic solution (Coconut water, Honey, Apple Cider Vinegar, commercial<br/>preparation and untreated) to enhance root and shoot development of gumamela<br/>cuttings.<br/> The experiment was laid out in 4 x 5 Factorial in Completely Randomized<br/>Design (CRD) with 3 replications. Each treatment<br/>consisted of 15 cuttings. The<br/>four Gumamela varieties used were: 'Aurora', 'Celia', 'Kona' and 'Gelia'. The<br/>organic solutions used were: Coconut water, Honey, Apple Cider Vinegar,<br/>commercial preparation and untreated.<br/> Results revealed that differences existed among the varieties. "Gelia' produced<br/>shoot earlier that 'Aurora', 'Celia', and 'Kona'. More shoots were produced also by<br/>"Gelia' compared to other varieties at 30 days after treatment (DAP). However at 60<br/>days, 'Celia' and 'Kona' produced more shoots compared to 'Aurora' and 'Gelia'.<br/>"Kona' at 30, 45 and 60 DAP produced more leaves than the other varieties. Longer<br/>shoots were produced by 'Celia' compared to 'Aurora', 'Gelia' and 'Kona' at 30,45<br/>and 60 DAP. Kona' produced more number of roots than 'Celia', 'Aurora' and<br/>"Gelia'. Longer roots (8.21 cm) were produced by Kona' compared with 'Celia'<br/>(6.19 cm), 'Gelia' (2.05 cm) and 'Aurora' (1.93 cm).<br/>The organic solutions did not affect the number of days to shoot formation,<br/>number of leaves produced, length (cm) of leaves, number and length (cm) of roots.<br/>However at 30 DAP, gumamela cuttings produced more shoots. Higher survival was<br/>observed at 30 DAP in cuttings treated with commercial preparation and the<br/>untreated, compared to the cuttings treated with coconut water, honey and apple cider<br/>vinegar.<br/> Based on the results of the study, it is recommended that for the propagation<br/>of the different varieties of gumamela 'Aurora', 'Celia', 'Kona' and 'Gelia', this<br/>could be enhanced by treating the cuttings with the commercial preparation, Hormex.<br/>"Kona' is the recommended variety in propagating gumamela using the organic<br/>solutions. The researcher also recommends the use of sand as rooting media instead<br/>of garden soil and rice hull, and when preparing the cuttings should be soaked<br/>immediately into the treatment solution before planting. For more conclusive results, further study should be conducted using coconut water, honey and apple cider vinegar<br/>to enhance the propagation of gumamela varieties.<br/> |
