Full text linkIn a long dried season, oil palm plant that planted in peat soil will hindered by drought stress. Drought stress is one of the main limiting factors in growth, nutrient uptake and yield of oil palm. One of the alternatives to overcome this drought stress problem on many plants is through inoculation with AMF. This research was conducted to observe the adaptability of oil palm seedling inoculated with AMF on drought stress in peat of used forest soil. The experiment on this soil type was arranged in a Factorial Completely Randomized Design with two factors. The first factor was AMF inoculation (M0= without AMF and M1 = inoculation of AMF) and the second factor was drought stress levels (available water 100%, 75%, 50% and 25%). Research  result indicates  that AMF inoculation improved the adaptability of oil palm seedling on every level of drought stress, as shown by the responses of growth and nutrient uptake. The adaptation of non-inoculated seedling on drought stress was solely by tolerance mechanism, either osmoregulation as shown by higher production level of osmoticum components or cell turgor regulation by leaf ABA accumulation. On the inoculated seedlings, however, there were synergism between those two tolerance mechanism and escape mechanism. Two important escape mechanisms were intensifying root system and decreasing transpiration surface of seedlings.  Key words : oil palm, AMF, drought stress, adaptation mechanis

PENGARUH NAUNGAN TEHADAP KERAPATAN STOMATA DAN TRIKOMA DAUN SERTA PERTUMBUHAN DAN HASIL DUA VARIETAS TANAMAN KEDELAI (Glycine max (L) Merril) (Effect of Shade on Stomatas and Trichomes Density and Growth of Two Soybean Varieties)
Full text linkDevelopment of soybean plants under intercropping standing crops often face many obstacles. Constraints faced by the plants grown in the area under the auspices of the stand, the light intensity is low stress. Stomata and leaf trichomes are character identifier for the adaptation of soybean plants that are in shaded conditions. This study aims to determine the interaction effect of varieties of the shade and density of stomata and leaf trichomes and growth and yield of two varieties of soybean plants. This experiment using split plot design (Split plot) with factorial pattern consisting of 2 factors. The first factor as the main plot (main plot) is a shade (N) which consists of two levels, namely without shade (N0) and 50% shade (N1). Both as a subplot factor (sub plot) is soybean varieties (V) consists of Petek (V1) and Jayawijaya (V2). The data obtained were then processed statistically by analysis of variance, followed by further testing LSD at α = 5% level. Other variables were observed between the density of stomata on the leaf surface, the surface density of trichomes on leaves, total leaf area, number of primary branches, number of pods per plant, number of pods per plant contains, and weight of 100 seeds. The final conclusion is that, 1) decrease low light intensity affect the stomata density and density of leaf trichomes and growth and yield of soybean. Treatment with 50% shade provision increasing the density of trichomes on the surface of soybean leaves but lower total leaf area, number of primary branches, stomatal density on the surface, number of pods per plant, number of pods per plant and weight contains 100 seeds. 2) Provision of shade 50% less likely to cause a low density of stomata and trichome density were higher in tolerant varieties (Petek) compared to susceptible varieties (Jayawijaya). 3) Testing the correlation coefficient between the variable density of stomata and trichomes with variable density growth and yield of soybean showed that the absence of the relationship between the main variables and variable growth or results.Keywords: Soybean, shade, Stomata, trichome
