ABSTRACTNutrient Enhancement In Cereal Crops Using Actinobacterial EndophytesWheat high demand without sufficient production and Actinobacterial endophytes usage limitation inIndonesia motivated this research. The aim was to determine Actinobacterial endophytes effect on nutrientenhancement in wheat (Triticum aestivum L.). It was hypothesized that they can enhance wheat nutrient.The experiment stages were: 1) Pot-Trial I, confirming nutrient enhancement using Actinobacteria in 6 soiltypes; 2) Pot-Trial II, screening Actinobacteria strains; and 3) Field-Trial. The results showed thatActinobacteria effects varied for different nutrients and site based differences. In Pot-Trial I, different soiltypes significantly affected the manganese and zinc content (P=0.00 and P=0.01), but not inoculation ofActinobacteria nor the combination of them. Field Trials showed the same trends. Combination betweenthose treatments significantly affected manganese content (P=0.045). Nutrient analysis on xylem sap in PotTrials 2 only showed the value differences since there was insufficient collected volume to be statisticallyanalyzed. Zinc and iron contents were the highest in Actinobacteria EUM165 treatment and the highestmanganese content in Actinobacteria EN16. In conclusion, wheat nutrient content is affected byActinobacteria and different soil types but there was insufficient evidence to generally conclude that it canbe enhanced. They have their own effects and affected each other in enhancing nutrient content.Keywords: Nutreint, wheat, endophytic ActinobacteriaABSTRAKTingginya permintaan gandum tidak disertai produksi yang cukup, serta terbatasnya pemanfaatanActinobacteria endofit di Indonesia, melatarbelakangi penelitian ini.

Tahapan penelitianmeliputi: 1) Uji-Pot I, mengonfirmasi peningkatan nutrisi gandum menggunakan Actinobacteria pada 6 jenistanah; 2) Uji-Pot II, menguji berbagai strain Actinobacteria terhadap peningkatan nutrisi gandum; serta 3)Uji Lapangan. Hasilnya menunjukkan bahwa Actinobacteria meningkatkan nutrisi gandum secara berbedatergantung nutrisi yang diuji serta jenis tanah yang digunakan. Pada Uji-Pot I, jenis tanah berpengaruhnyata terhadap kandungan mangan dan seng (P=0.00 dan P=0.01), tapi pemberian Actinobacteria maupunkombinasi keduanya tidak. Uji Lapangan menunjukkan hasil yang sama. Kombinasi kedua perlakuanmeningkatkan kandungan mangan secara signifikan (P=0.045). Analisis cairan xilem dari Uji-Pot IImenunjukkan perbedaan hasil tanpa uji statistik karena terbatasnya cairan yang dikumpulkan. Kandungantertinggi seng dan zat besi ditunjukkan oleh perlakuan Actinobacteria EUM165 dan mangan yang lebihtinggi oleh Actinobacteria EN16. Disimpulkan bahwa kandungan nutrisi tanaman gandum dapatdipengaruhi oleh pemberian Actinobacteria endofit serta perbedaan jenis tanah, namun tidak cukup buktiuntuk menyimpulkannya secara umum. Baik jenis tanah maupun Actinobacteria endofit memiliki pengaruhsendiri serta saling mempengaruhi terhadap kandungan nutrisi tanaman gandum.Kata kunci: Nutrisi, gandum, actinobacteria endofit

Matter Basis

Manganese deficiency of subterranean clover (Trifolium subterraneum L.) appeared in pots of a Kangaroo Island soil, the pH of which had been changed by the addition of small amounts of lime from 6.2 (the natural pH) to 6.3-6.5. As a result of this deficiency, yields were severely depressed. The symptoms of manganese deficiency in subterranean clover are described. Chemical analyses of healthy plants showed manganese contents, expressed on a dry matter basis, varying from 30 p.p.m. on a slightly acid soil to over 300 p.p.m. on a strongly acid soil. Plants in various stages of manganese deficiency showed only 4-25 p.p.m. It is suggested that, at the flowering stage, 25 parts of manganese per million parts of dry matter represents the minimum amount of manganese for healthy growth of subterranean clover. Applications of manganese sulphate to the soil at a rate of 56 lb/acre prevented the appearance of manganese deficiency symptoms, increased the manganese content of the clover to 35 p.p.m., and led to nearly a 20-fold increase in growth. Manganese deficiency in subterranean clover has also been seen in the field on Kangaroo Island and one sample examined showed only 9.4 p.p.m. of manganese on a dry matter basis.

Seed Manganese

The influence of manganese nutrition on growth and yield of two soybean cultivars (Lee and Bragg) was studied in sand culture. Increasing the manganese concentration from 1.0�M to 275�M reduced vegetative growth and grain yield in both cultivars, the reduction being greater for Bragg than for Lee. The reduction in grain yield at high manganese levels resulted mainly from a reduced individual seed weight and a lower number of pods, with a slight reduction in the number of fertile nodes. There was no effect of high manganese supply on oil and protein levels or on the germination percentage of harvested seed. Manganese deficiency reduced vegetative growth, advanced flower initiation and pod formation, and decreased the grain yields of both cultivars. The reduced seed yield was mainly due to a reduction in the number of pods per plant and the individual seed weight. Manganese deficiency also reduced the concentration of oil in the seeds, but there was no effect on seed protein level or on the germination percentage cf harvested seed. Seed manganese concentration increased with the supply of the nutrient, but no difference in concentration was found between the two cultivars.

Mn Concentrations

Manganese deficiency is a common and potentially fatal disorder of palms growing in highly leached and calcareous soils. Soil applications of MnSO4 may not always be effective in treating this disorder due to rapid oxidation of Mn to less available forms. Trunk injection with MnSO4 (2.0 g Mn) was found to be more effective in increasing foliar Mn concentrations than soil application (192 g Mn) or petiole injections with 0.1 g Mn in a single hole, or 0.5 g Mn divided among four holes. In contrast to trunk injection, neither petiole injections nor soil application of MnSO4 increased foliar Mn concentrations above that of the untreated control palms. Trunk injections, while effective, result in permanent wounds that could potentially serve as entry sites for the trunk pathogen Thielaviopsis paradoxa, especially on young palms with minimal trunks.

Nutrient Solutions

The mobility of manganese from old leaves and cotyledons during vegetative growth has been examined by following manganese content and radioactive manganese redistribution in parts of subterranean clover plants grown into manganese deficiency. In plants transferred from nutrient solutions with 1 �M Mn2+ to solutions without Mn2+, the amount of manganese in the roots decreased markedly. During the same period there was no net loss of manganese from cotyledons and old leaves, although plants developed severe manganese deficiency symptoms in young leaves. Old leaves of plants given an early supply of 54Mn lost no 54Mn when the plants were transferred to non-radioactive solutions without manganese for 14 days. Silicon, which is known to influence the distribution of manganese within leaves of some plants, had no effect on the loss of total manganese or 54Mn from old leaves. Detached green, mature leaves lost 40% of their manganese within 24 h when aerated in water. If leaching by rain removes substantial amounts of manganese from leaves of plants grown in the field, this may account for reports of manganese mobility in plant phloem. The present results establish that manganese is not mobile in the phloem of subterranean clover plants during vegetative growth.

SUMMARY1. Pot and field experiments were made to compare the effects of thiosulphates and sulphur on the incidence of manganese deficiency in oat, beet and pea grown in two manganese-deficient soils.2. The addition of sodium or calcium thiosulphate to oat plants growing in a manganese-deficient fen soil in boxes markedly reduced symptoms of ‘grey speck’ and increased the soluble manganese content in the leaf tissues, but the effect was transient.3. The growth of beet in this soil in clay pots was improved by the addition of thiosulphates, and also by painting the exterior of the pots with bitumen paint or by covering the surface of the soil with a thin layer of sand. The thiosulphate treatments increased the manganese uptake by the plants and reduced the symptoms of manganese deficiency, particularly when applied to pots painted with bitumen paint.4. Field experiments with an old garden soil deficient in manganese showed that thiosulphate treatments increased the manganese uptake of beet. Placement treatments were more effective than broadcast treatments and greatly improved the growth of beet and reduced or eliminated manganese-deficiency symptoms, without producing any change in soil pH.
