Effect of Type of Natural Substances Plant Growth Regulator on Nutmeg (<em>Myristica Fragrans</em>) Seedlings

Abstract

Nutmeg (&lt;em&gt;Myristica fragrans Houtt&lt;/em&gt;) is an important spices in Indonesia. The advantages of nutmeg is essential oil content, the result of distillation which is for the spices industry, the manufacture of soaps, perfumes, cosmetics, have high economic value and are a source of foreign exchange to non oil &amp;amp; gas, Indonesia is able to supply the needs of the market the world of up to 70% to 75%. Generally, nutmeg in Indonesia use generative propagation which has the strong root system and long life, but the germination takes a long time. Using the natural plant growth regulators for germination can be used to accelerate growth. Natural PGR’s can be extracted from some plants such shallot as a source of auxin, banana hump as a source of cytokinins, and bamboo shoots as a source of giberellin.The purpose of this study was to determine the types of natural PGR’s that have good effect on the growth of nutmeg seedling. The experiment was carried out in Desa, Bugel, Kecamatan Ciawi Tasikmalaya with altitude at 600 meters above sea level, from June 2018 to September 2018. This study used Randomized Completely Block Design (RCBD) Method. The treatments were: a0= control, a1= shallot, a2= bamboo shoot, a3= banana hump, a4= shallot + bamboo shoot, a5= shallot +, banana hump, a6= bamboo shoot + banana hump, a7= shallot + bamboo shoot + banana hump.The result showed that:1) type of natural substances plant growth regulator effected on various growth variable, 2) Combination of shallot bulb + bamboo shoot, or combination of shallot bulb + bamboo shoot and banana hump good effected on plant height, seedling diametre, number of leaf, leaf area, and shoot root ratio.

DIFFERENCES OF PLANTING MEDIA AND CONCENTRATION OF ONION (Allium ascalonicum L) EXTRACT TOWARDS BODY GUAVA CITRA (Syzygium aquenum Burn)

“…Each treatment was repeated 3 times so that there were 36 polybags. The results of this study showed that in observing the number of shoots the best-growing media treatment was T0 at the age of 6 WAP (4.33) and 7 WAP (4.56), the best concentration of onion extract was treatment B1 at 6 WAP (3,50) and 7 WAP (4,67), observing the number of roots with the best treatment B1 at the age of 8 WAP (3.00), observing the number of roots with the best B1 at the age of 8 DAP (3,96). There was no interaction between the growing media and onion extract.…”

“…It was further stated that if the cytokinin concentration was smaller than auxin, it would stimulate root growth, and if the cytokinin concentration was balanced with the auxin concentration, the shoot, leaf, and root growth would be balanced as well. According to Kurniati et al, 2019) that the onion extract contains high cytokinins close to the auxin content, namely 122.34 ppm and 140.11 ppm.…”

Penggunaan Pupuk Organik Cair Berfitohormon Jagung Pada Tanaman Sayuran di Pekarangan Rumah pada Kegiatan Abdimas Lingkungan

“…Tanaman sayuran yang ditanam di pekarangan rumah akan menghasilkan kualitas sayuran yang baik jika dilakukan pemeliharaan yang tepat salah satunya dengan diberi pupuk (Cokrowati & Diniarti, 2019;Herlina, L., K.K. Pukan, 2016;Kurniati et al, 2019;Rahmawati, 2021;Rahni, 2012). Pupuk yang disarankan adalah pupuk organik cair berfitohormon.…”

The Effect of Shallot and Tomato Extract Consentrations on the Growth of Mangosteen Seedling (Garcinia mangostana L.)

“…Hal ini akibat efek dari zat yang terkandung dalam bawang merah terutama zpt alami, seperti auksin, sitokinin, dan giberelin. Menurut Kurniati et al (2019) 3.26 b 100 g L -1…”
