PENGATURAN PEMBUNGAAN TANAMAN JAMBU BIJI (Psidium guajava L.) ‘KRISTAL’ MELALUI APLIKASI WAKTU STRANGULASI YANG BERBEDA

ABSTRACT Arrangement of Guava Flowering (Psidium guajava L.) ‘Krystal’ through the Application of Different Strangulation Times. The seasonal production of guava (Psidium guajava) requires flowering manipulation technique such strangulation in order to be available throughout the years. This study aimed to explain the relationship between strangulation time, the period of flowering and harvesting of guava cv 'Krystal'. The experiment was conducted from February to December 2017, in Cikabayan experimental garden of IPB University, Bogor, Indonesia. The experiment used a completely randomized design with single factor, i.e strangulation times that consisted of control (no strangulation), strangulation in March, in April and in May. The results showed that strangulation treatment was able to accelerate the emergence of flowers and increase the number of generative shoots, the number of flowers per tree and the number of fruits harvested. The increase of flowering response on strangulated trees was supported by a higher leaf C/N compared to control, which is related to the low leaf N content in strangulation treatments. The strangulation treatment could accelerate the time of flower emergence six days earlier than control. Keywords: guava, C/N, flowering induction, ringing, seasonal production ABSTRAK Produksi buah jambu biji (Psidium guajava) yang bersifat musiman memerlukan teknik pengaturan pembungaan agar dapat tersedia sepanjang tahun. Penelitian ini bertujuan untuk menjelaskan keterkaitan antara waktu strangulasi dengan pola pembungaan dan panen buah jambu biji ‘Kristal’. Percobaan dilaksanakan mulai Februari sampai Desember 2017, di Kebun Percobaan Cikabayan IPB Bogor. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan faktor tunggal yaitu waktu strangulasi yang terdiri dari 4 (empat) taraf, yakni tanpa strangulasi, strangulasi bulan Maret, strangulasi bulan April dan strangulasi bulan Mei. Hasil penelitian menunjukkan bahwa perlakuan strangulasi mampu mempercepat munculnya bunga dan meningkatkan jumlah tunas generatif, jumlah bunga per pohon, jumlah bakal buah per pohon dan jumlah buah yang dipanen. Peningkatan respon pembungaan akibat strangulasi didukung oleh C/N daun yang lebih tinggi dibandingkan tanpa stangulasi, yang berhubungan dengan rendahnya kandungan nitrogen daun pada perlakuan strangulasi. Perlakuan strangulasi mampu mempercepat waktu muncul bunga 6 hari lebih cepat dibandingkan tanpa strangulasi.Kata kunci: jambu biji, C/N, induksi pembungaan, pencekikan batang, produksi musiman

Guava leaves can be used as a natural preservative in quail carcass because they contain antimicrobial compounds such as flavonoid and tannin. This study studied the effect of using guava leaves infusion on quail carcass on the total bacteria, Enterobacteriaceae, and early spoilage. The research used an experimental method with a completely randomized design, 3 treatments of guava leaves infusion concentration, namely P1 = 25%, P2 = 50%. And P3 = 75%, each treatment was repeated 6 times. The application of infusion to quail carcass was carried out by immersion for 15 minutes. Data were analyzed using ANOVA and Turkey’s test. The results showed that the total bacteria and Enterobacteriaceae before immersion were 3.80 x 107 cfu/g and 1.90 x 104 cfu/g, respectively. Soaking quail carcass in guava leaves infusion was able to reduce the total bacteria and Enterobacteriaceae to 72.15% and 78.50%, respectively. The early spoilage was inversely proportional to the total bacteria and Enterobacteriaceae resulted in longer shelf life.

The Relationship

The effects of two silvicultural herbicides (Vision®, Release®) on bryophytes and lichens were studied in a harvested boreal mixedwood ecosystem. A completely randomized design with 115 plots of 1 m2 allowed direct comparison between herbicides and their effects on community dynamics. Regression models were used to analyze the relationship between herbicide application rates (0.71-6.72 kg active ingredient/ha) and changes in bryophyte and lichen abundance and species richness for 2 years following herbicide application. Results showed that bryophyte and lichen abundance and species richness decreased after herbicide treatments. In general, herbicide applications reduced the diversity of forest mesophytes and weedy colonizers to an ecosystem with only a few species of colonizers. A combination of clustering techniques and ANOVA were used to divide bryophytes and lichens into three ecologically defined response groups: herbicide-tolerant colonizers, semi tolerant long-term stayers from dry open forest, and sensitive forest mesophytes.

ABSTRACT Salinity influences all germination stages and may adversely affect seedling establishment in the field. The objective of this research was to determine the relationship between the antioxidant activity and the physiological performance of seeds and to verify the efficacy of the imaging analysis of popcorn seedlings after seed exposure to saline stress. A completely randomized design was used that consisted of four replicates in a factorial scheme. This scheme comprised three popcorn hybrids (P618, AP6002, and AP8203) and five saline potential levels (0.0; -0.1; -0.3; -0.6, and -0.9 MPa) that were obtained from KCl solutions of different concentrations. First count germination, germination and seedling vigor classification (strong normal seedlings), and dry mass of seedlings were evaluated to determine the physiological quality of the seed. The images of seedlings were used to evaluate the coleoptile and root lengths, indices of vigor, uniformity, and growth using the Groundeye® software. The activities of the antioxidant enzymes superoxide dismutase (SOD), ascorbate peroxidase (APX), and catalase (CAT) were also determined. Saline stress compromises the physiological quality and antioxidant activity of seeds and the performance of popcorn seedlings. Computerized image analysis using Groundeye® was efficient in evaluating the popcorn seedlings after being subjected to salt stress. Hybrids AP6002 and AP8203 were more tolerant to salt stress than hybrid P618.
