The peak production of BPM 24 clone rubber  was reached in the 7th to 10th year, but production quickly declined to reach its lowest point in 15 years. Stimulants are technologies used to increase production. Stimulants generally contain ethylene. Ethylene affects the balance of sucrose in latex formation and also increases metabolic activity in latex vessel cells. The purpose of this study is to know the physiological character response of rubber plants (hevea brasiliensis Muell. Arg) clone BPM 24 against the application of organic ethylene stimulant banana peel. The research was conducted in september to november 2019 at the research center of rubber experimental garden Sumbawa in Palembang, South Sumatra. This research method is descriptive with treatment: without stimulant, ethrel 10 PA, banana peel Ambon concentration 333 g/L, banana peel Ambon concentration 500 g/L, banana peel Ambon concentration 666 g/L, banana skin wax concentration 333 g/L, banana skin wax concentration 500 g/L, banana skin wax concentration 666 g/L, banana peel Kepok concentration 333 g/L, banana peel Kepok concentration 500 g/L, banana peel Kepok concentration 666 g/L. Observations are carried out on physiological character (thiol levels, inorganic phosphate levels, sucrose levels and dry tapping grooves. The treatment of banana skin stimulant is able to increase the production of latex without interference in the physiological character of the plant, but the use of stimulants with excessive and inappropriate doses can lead to the onion of dry tapping grooves.

Aims: In order to achieve a good and sustainable harvest of Hevea brasiliensis rubber, the effect of exogenous hormonal stimulation on the metabolic partition growth-production of clones according to the class of metabolic activity was made. Place and Duration of Study: The study was conducted for 9 years in the San-Pedro region in south-west Ivory Coast, precisely in the experimental industrial plantations of the former HEVEGO, now Southwestern Agricultural Civil Society Société (SCASO). Methodology and Results: The rubber trees were planted at a density of 510 trees/ha in a completely randomised system. They were bled in S/2 d4 and stimulated to 2.5% Etephon at annual frequencies of 0, 1, 2, 4, 6, 8, 13, 18, 26, 39 and 78. The parameters measured were rubber production, trunk circumference, sucrose content, inorganic phosphorus, thiol groups and dry notch rate. The results showed that productivity increased with the intensity of stimulation (58.96 - 68.49 g.a-1.s-1 ; 39.83 - 66.69 g.a-1.s-1) over the intervals [0.6] and [0.26] stimulations respectively in clones with active and slow metabolism. The circumference of the trunk was marked by a less pronounced decrease in growth in slow metabolizing clones (0.52%) with good protection of the laticigene system (R-SH : 0.815 mmol.l-1) and low sensitivity to dry notching (1.6). Whatever the classes of metabolic activity of the clones, the agrophysiological parameters were strongly correlated with each other by a degree 2 polynomial function. Conclusion: This polynomial function seems to reflect the existence of a good state of equilibrium between laticigenic metabolism and vegetative growth according to the class of metabolic activity of the Hevea brasiliensis clones.

Chrysanthemum is an ornamental flower plant that has advantage because of various colors and has long vase time. The minimum potential for chrysanthemum development in Bangka is because of limited seed and the enviroment conditions in Bangka are less than optimal for chrysanthemum plants. The increasing chrysanthemum seedlings can be done vegetatively by addition of IBA hormone with an ex-vitro system. This study aims to determine the effect of IBA (Indole Butyric Acid) hormone on the growth of chrysanthemum cuttings in Bangka. This research was conducted from March to May 2020 at the Research and experimental Garden, Faculty of Agriculture, Fisheries and Biology, Universitas Bangka Belitung. The research method used an experimental method with a single completely randomized design (CRD) consisting of 6 treatments, namely (Control), IBA 50 ppm, IBA 100 ppm, IBA 150 ppm, IBA 200 ppm, IBA 250 ppm. The results showed that giving IBA had no significant effect on the growth of chrysanthemum cuttings in Bangka. Treatment (IBA 150 ppm) tends to be better for the growth of chrysanthemum cuttings in Bangka.

SUMMARYThe concentrations of lactose, glucose, glucose 6-phosphate, glucose 1-phosphate, UDPglucose, UDPgalactose, UDP, UMP, inorganic phosphate, ADP and AMP (metabolites involved in the lactose synthesis pathway), and cAMP, galactose and fructose were measured in the mammary secretion from sucked (n = 9) and unsucked (n = 4) mammary glands of nine sows during the first 5 d post partum. The concentrations of lactose, glucose, galactose and fructose were also measured in plasma during this time. The progressive increase in the concentration of lactose, and changes in the concentrations of cellular metabolites in the mammary secretion from sucked glands were consistent with an increase in the metabolic activity of those glands during lactogenesis II. In contrast, unsucked glands showed a progressive decrease in the concentration of lactose, while the concentrations of cellular metabolites in the milk generally remained unchanged. These results indicated that there was no increase in the metabolic activity of unsucked glands (no increase in lactose synthesis or utilization of glucose and ATP) and that the rate of lactose synthesis prior to milk removal was limited by the availability of glucose and/or UDPgalactose. Therefore, the removal of colostrum from the mammary gland was necessary for an increase in the rate of lactose synthesis (and probably de novo fatty acid synthesis) and implies that autocrine mechanisms are operating to control the rate of milk synthesis during lactogenesis in the sow. The low concentration of glucose in colostrum compared with that in plasma is discussed in view of the paracellular pathway.

Most people understate that latex harvesting is merely cutting the bark and collecting the sap. Since it was cultivated in the monoculture plantation system, rubber (Hevea brasiliensis) harvesting system has been transformed continually. This article presents the transformation of rubber harvesting systems, tapping innovations that have been developed, and the current condition of rubber agribusiness and its impact on the tapping system applied. At the beginning of the development of the rubber cultivation era, tapping was conducted with multiple slicings to gain high rubber yield. This system turned into one slice to extend the economic span of the plant. The invention of latex stimulants transformed the rubber tapping system from once every two days (d2) without stimulants to once every three days (d3) with stimulants. In the case of the tapping technique, several tapping systems have been developed, including puncture tapping, upward and double-cut tapping, Alternate Tapping System, and Change Over Panel. Except for the puncture tapping, those tapping systems are still used nowadays. Latex diagnosis, that is the measurements of the sucrose, inorganic phosphate, and thiol contents in the latex, became the basis of clonal grouping and the clonal typology tapping system. The current low rubber price renders the adoption of low-frequency tapping systems (d4, d5, or d6) with high dose and frequency of stimulant application. In the future, the low-frequency tapping system will remain the ultimate choice as labor costs continue rising. Besides, the use of sensory technology and digital instruments is being widely studied, which indicates that the latex harvesting system in rubber plants is believed to continue to develop. Keywords: Hevea brasiliensis, latex diagnosis, latex yield, stimulant, tapping   ABSTRAK Sebagian besar masyarakat beranggapan bahwa memanen lateks hanya mengiris kulit dan menampung getahnya. Namun sebenarnya, sejak dikembangkan dalam sistem perkebunan monokultur, sistem pemanenan lateks karet (Hevea brasiliensis) terus mengalami pembaharuan. Artikel ini menyajikan transformasi sistem pemanenan lateks tanaman karet, inovasi-inovasi yang pernah dikembangkan, serta kondisi agribisnis karet saat ini dan dampaknya terhadap sistem sadap yang diterapkan. Pada awal perkembangan perkebunan karet, penyadapan dilakukan dengan banyak irisan untuk mendapatkan hasil sebanyak-banyaknya. Ini kemudian berubah menjadi satu irisan untuk memperpanjang umur ekonomis tanaman. Penggunaan stimulan mengubah sistem penyadapan karet dari dua hari sekali (d2) tanpa stimulan menjadi tiga hari sekali (d3) dengan stimulan. Dalam hal teknis, beberapa sistem sadap pernah dikembangkan antara lain, sadap tusuk, penyadapan ke arah atas, sadap ganda, Alternate Tapping System, dan Change Over Panel. Selain sadap tusuk, inovasi-inovasi penyadapan tersebut tetap digunakan sampai saat ini. Diagnosis lateks melalui pengukuran kadar sukrosa, fosfat anorganik, dan thiol dalam lateks, menjadi dasar pengelompokan klon dan penyadapan tipologi klonal. Harga karet yang rendah saat ini menyebabkan perusahaan perkebunan cenderung mengadopsi sistem sadap frekuensi rendah (d4, d5, atau d6) dengan dosis dan frekuensi stimulan yang tinggi. Di masa yang akan datang, sistem sadap frekuensi rendah akan tetap menjadi pilihan utama karena upah tenaga kerja terus meningkat. Selain itu, penggunaan teknologi sensorik dan instrumen digital mulai banyak diteliti. Melihat fakta-fakta ini, sistem pemanenan lateks pada tanaman karet diyakini akan terus berkembang.

Factors Influencing

The density of tapped rubber trees in a plantation is a determining parameter of its productivity. It is related to the number of trees planted per hectare, the evolution of which can be influenced by several factors that act on the trees from the year of establishment to the time of tapping. To this end, a study to determine the evolution of the rate of live trees and tapped trees of eight rubber clones during the first fifteen years of establishment was carried out in southwestern Côte d'Ivoire. At opening, rubber trees planted at 510 trees/ha (7 m x 2.80 m) were bled in a descending half-spiral at different tapping and stimulation frequencies. The experimental design was a Fisher block design with 6 treatments (d2, d3/4y, d4/4y, d4/8y, d5/8y, d6/10y) and 3 replications. The results revealed that the rate of live trees and tapped trees was not influenced by either clone or latex harvesting treatment. The rate of live trees decreased progressively from the immature phase of the plantation (94.71 ± 1.34%) to the end of the downward tapping (91.55 ± 0.67%). The rate of tapped trees increases from the time of planting (69.51 ± 8.03%), over the years (92.00 ± 1.39%) until it equals the rate of live trees (92.00 ± 1.08%) before gradually decreasing to 88 ± 3.78%. It should be noted that the factors influencing the evolution of the rates of live and taped trees caused less damage to the rubber trees. And this influence is not dependent on clone, metabolic activity class and latex harvesting system.
