Abstract

Red Jabon (Anthocephalus macrophyllus (Roxb.) Havil) is a forest plant that can replace sengon (Falcataria moluccana) because it has advantages. The demand for red jabon wood is increasing, but the cultivation of red jabon is still constrained by the attack of pathogens that cause leaf disease. The attack of these pathogens can cause damage and death of seedlings so that it can be economically detrimental. The aim of this study was to identify the pathogens that cause disease in red Jabon. The method used is the Postulate Koch method, which starts from sampling red leaves with leaf disease symptoms, isolation, inoculation and analysis of disease incidence, re-isolation, and identification. Based on the identification results found as many as 2 pathogenic fungi that cause leaf spot disease, namely Pestalotia sp. and Rhizoctonia sp. In addition, 6 pathogenic fungi were found that cause blight, namely Lasiodiplodia theobromae, Fusarium sp., Colletrotrichum sp., Marssonina sp., Gloeosporium sp. 1, Gloeosporium sp. 2. Keywords: identification, percentage of disease incidence, Postulat Koch, red jabon

Abstract

Java kenanga or kenanga (Cananga odorata f. macrophylla) is a tropical and sub-tropical tree species that grows naturally in Indonesia and produces essential oil. This species has been cultivated in the past by community in Indonesia, mainly on their yard. The population of kenanga has decreased significantly, but in Blitar district the community is still doing cultivating the species although in a small scale. The purpose of this research is to observe the cultivation efforts by the community and also kenanga flower production in Blitar district. This research was conducted by interviewing farmers and observation of kenanga trees in the field. The results showed that cultivation efforts being made to improve the production of kenanga flower is by pruning, fertilizing, flowering routine and retrieval or emoval of kenanga fruit. The average kananga flower production reached 381 kg / year / tree in the age group above 11 years. Factors that affect flower production were tree age (years), total tree height (m), diameter at breast height (cm) and the width tree canopy (m2). The most significant factors affecting flower production were tree diameter and width of tree canopy. Cultivation efforts being made to improve the production of kenanga flower is by pruning, fertilizing, flowering routine and retrieval or removal of kenanga fruit.

Abstract

Bruguiera gymnorrhiza is a mangrove species that can be used to rehabilitate mangrove forest. The information about the response of mangrove seedlings to the factors that affect its growth is needed to ensure its survival rate. This study aimed to examine the response of Bruguiera gymnorrhiza seedlings to the factors that affect its growth such as media and shade level. This research used a Completely Randomized Factorial Design (CRFD) with the treatments of growing media (A) and shade level (N) of 3 levels on each factor, that are mud (A0); mud and compost (A1); and mud, compost, sand (A2); also 0% shade (N0); 50% shade (N1); and 70% shade (N2) on the 3 months old seedlings. The results showed that the treatment of shade level significantly affected the growth response of B. gymnorrhiza seedlings, while the treatment of growing media and interaction of both treatments did not show a significant response. The 0% shade level gave the best growth response of B. gymnorrhiza seedlings. Keywords: Growth rate, light level, mangrove, rehabilitation, seedbed

Abstract

The presence of Pericopsis mooniana (Thw.) Thw. in nature is endangered. Meanwhile, Pericopsis mooniana plants have its obstacles in generative propagation because the seeds have mechanical dormancy. Studies carried out to: (1) observe the morphology of pods, seeds and sprouts of Pericopsis mooniana; (2) determine the physical quality of Pericopsis mooniana seeds, and (3) analyze the proper dormancy breaking treatment for Pericopsis mooniana seeds. Research is conducted in laboratories and in greenhouses. The physical quality of the seeds measured was the weight of 1,000 seeds and the moisture content. The treatment for breaking the dormancy of the Pericopsis mooniana seeds were control, scarification of the seeds using nail clippers and soaking in hot to cold water for 48 hours. Morphologically, the fruit of Pericopsis mooniana is pod-shaped, with orange seeds, oval-shaped and curved edges. Pericopsis mooniana sprouts include in the epigeal type. In 1 kg of weight there are ± 4,000 Pericopsis mooniana seeds, with the post harvest seed moisture content amounting to 7.62%. The dormancy breaking treatment of Pericopsis mooniana seeds increased seeds germination by 60% compared to controls. The scarification of Pericopsis mooniana seeds using nail clippers for breaking mechanical dormancy is the best treatment because it can increase the number of seeds germinating in a short time and simultaneously. Key words: breaking seed dormancy, morphology, Pericopsis mooniana, physical quality, seed scarificatio
