Abstract

The aim of this research is to analyze and examine the inheritance of stomatal density trait and RWL as a variable in drought tolerance ofpeanut. The experiment was conducted by using cv. Kelinci that is sensitive genotype as female parent and US 605 which is tolerantgenotype as male parent, including population off spring from hybrid cv. Kelinci (P1) with US 605 (P2). Stomatal density was determinedby making leaf imprint and by observing leaf imprint under microscope. Relative water loss was determined by dipping peanut leaf in PEG40% for 48 hours. Result of the analysis showed that stomatal density and RWL were not only controlled by qualitative characters of majorgene, but also controlled by quantitative character of minor gene by polygenic with the complex gene action. Both characters seem toinfluence more as genetic factor and have high level fixation additive varians which can give the opportunity to obtain the tolerant offspring.

Abstract

Untuk mengetahui pengaruh keke-ringan pada tanah bergaram NaCl terhadap pertumbuhan tanaman nilam (Pogostemon cablin Benth.) telah dila-kukan penelitian di rumah kaca Balai Pene-litian Tanaman Obat dan Aromatik (Balittro) Bogor pada Juni sampai November 2007. Faktor yang diuji adalah : 1) keadaan tanah, terdiri atas 2 taraf (keadaan lembap dan kering); dan 2) kadar garam NaCl tanah terdiri atas 3 taraf (0, 1.000, dan 2.000 ppm). Faktor-faktor yang diuji tersebut disusun dalam ran-cangan acak lengkap dengan 10 ulangan. Sedangkan parameter yang diamati meli-puti komponen tinggi tanaman, jumlah daun, jumlah buku, jumlah cabang, dia-meter batang, serta bobot basah dan kering biomas. Hasil penelitian menun-jukkan bahwa faktor keadaan dan kadar garam NaCl tanah mempengaruhi pertum-buhan tanaman nilam. Pengaruh interaksi antara kedua faktor tersebut hanya dijum-pai pada komponen diameter batang. Pada kondisi tanah kering, kadar garam NaCl 1.000 ppm atau lebih sangat nyata meng-hambat pertumbuhan diameter batang, tetapi tidak berpengaruh ketika tanah cukup lembap (basah). Kedua faktor secara individu berpengaruh nyata ter-hadap komponen pertumbuhan lainnya pada tanaman nilam. Keadaan tanah basah nyata lebih baik pengaruhnya ter-hadap perkembangan tanaman dibanding tanah  dengan  keadaan  kering.  Demikian   pula kadar garam NaCl tanah yang semakin meningkat ternyata semakin memperburuk pertumbuhan dan perkembangan tanaman nilam.

Abstract

Managing soils is a beneficial effort allowing plants to grow and have dense fruit as well as to avoid them from damaging. Lack of knowledge about soil management may be related to poor soil management performance. To identify differences on farmers’ knowledge about managing soils based on their educational degree and participation in farmer group organization, thisresearch was conducted on Villages of Sukatani, Cianjur and Wates Jaya, Bogor from November to December 2012. A descriptive method with survey technique was used. Knowledge score using a multiple choice test was obtained from 89 samples selected by simple random sampling. In prerequisite testing, data was found homogenous but in abnormal distribution. Therefore, the hypothesis testing then was carried out with non-parametric tests. The average comparative rate of farmers’ knowledge based on educational degree using the Kruskal-Wallis test showed a non significant differences (p &gt; α at 0.393 &gt; 0.05). This occurred because farmers gained the knowledge through parental manner. Similarly, the average comparative rate of farmers’ knowledge based on their participation in farmers’ organization using the Mann-Whitney U test also showed a non-significant differences (p &gt; α at 0.770 &gt; 0.05). This happened because the farmers did not receive information delivered by the organization appropriately or they did not use the organization as a source of information in managing the soils. As the conclusion, educational degree and participation in organization did not cause differences to farmers’ knowledge of soil management.
