Until now sandy soils can be considered as one roup having common hydrophysical problems. Therefore, a labo-ratory experiment was conducted to evaluate the influence of bagasse as an amendment to improve hydrophysical properties of sandy soil, through the determination of bulk density, aggregate-size distribution, total porosity, hydraulic conductivity, pore-space structure and water retention. To fulfil this objective, sandy soils were amended with bagasse at the rate of 0, 0.5, 1, 2, 3 and 4% on the dry weight basis. The study results demonstrated that the addition of bagasse to sandy soils in between 3 to 4% on the dry weight basis led to a significant decrease in bulk density, hydraulic conductivity, and rapid-drainable pores, and increase in the total porosity, water-holding pores, fine capillary pores, water retained at field capacity, wilting point, and soil available water as compared with the control treatment.

High salinity interferes in sugarcane growth and development, affecting not only crop yield but also reducing sucrose concentration in culms. Sugarcane plants submitted to salt stress can accumulate compatible solutes, such as proline, which may counteract the effects of salt accumulation in the vacuole and scavenge reactive oxygen species. The objective of this study was to evaluate the response to salt stress of sugarcane plants transformed with the Vigna aconitifolia P5CS gene, which encodes Δ1- pyrroline-5-carboxylate synthetase, under the control of a stress-induced promoter AIPC (ABA-inducible promoter complex). For this, 4-month-old clonally multiplied sugarcane plants from two transformation events were irrigated every 2 days with 1/10 Hoagland’s solution supplemented with 100, 150 and 200 NaCl, progressively, during 28 days. Transgenic lines showed increased transgene expression in 3.75-fold when compared with the control plants after 9 days of irrigation with saline water, which can explain the higher proline concentration found in these plants. At the end of the experiment (day 28), the transgenic lines accumulated up to 25 % higher amounts of proline when compared with non-transformed control plants. Stress response in transgenic plants was also accompanied by a reduction of malondialdehyde (MDA) derived from cellular lipid peroxidation in leaves, lower Na⁺ accumulation in leaves and maintenance of photochemical efficiency of PSII. Thus, proline contributed to the protection of the photosynthetic apparatus and the prevention of oxidative damage in transgenic sugarcane under salt stress.

The sugarcane stalk borers, Sesamia spp. (Lepidoptera: Noctuidae) are the most destructive sugarcane insect pests in Iran. The efficiency of Telenomus busseolae Gahan (Hymenoptera: Scelionidae) used alone or in combination with silicon fertilization was investigated for controlling the sugarcane stalk borers under field conditions. The treatments were: a combination of silicon plus multiple releases of 2,500 T. busseolae, and multiple releases of 5,000, 2,500 and 1,250 T. busseolae alone. Plots receiving no soil amendment or parasites were included as the controls. Three weeks after the first application of each treatment, 100 shoots were selected randomly from each plot and the percentage of dead heart was determined. Then, three months after the first application of parasites, the percentage of stalks damaged, the percentage of internodes bored, and the level of parasitism were determined. Finally, at harvest the percentage of stalks damaged, the percentage of internodes bored, and sugarcane quality characteristics were determined. Results indicated that the efficiency of parasitism increased when combined with an application of silicon fertilizer. The release of 2,500 T. busseolae followed by an application of silicon fertilizer decreased dead hearts to 4%, while 12% dead hearts was observed in the control plots. For the combination treatment, the percentages of stalk damage were 1.5% and 17.2%, at 3 weeks and 3 months after time release, respectively. However, the percentages of stalk damage were 35.2% and 51% when no treatment was applied. Cane quality was significantly higher with the application of silicon fertilizer plus the release of 2,500 T. busseolae, followed by releasing 5,000 Hymenoptera. The level of parasitism was also greater when parasites were released in combination with an application of silicon. We conclude that biological control by egg parasitoids can be enhanced with concurrent applications of silicon fertilizer as a soil amendment and thereby creating a more robust, Integrated Pest Management (IPM) program of stalk borers in Iranian sugarcane fields.

An efficient protocol for induction of callus and regeneration of a sugar cane var 93v297 has been developed and reported here. Callus induction from immature young leaf explants derived from 2-3-month-old plants was achieved on Murashige and Skoog’s (MS) medium supplemented with different auxins viz, 2,4-D, NAA and IAA. Among different auxins, 2, 4-D at 3.5mg/l + 0.5mg/l BAP was found favourable in inducing callus. Addition of coconut milk and BAP further enhanced the growth of callus maximum being on MS medium supplemented with 0.5mg/l BAP (3602.33±0.88mg). Calli were further evaluated for regeneration. MS medium supplemented with 1.0 mg/l BAP was found suitable where 100% calli regenerated with maximum number of multiple shoots per callus mass (41.40±0.89). Highest number of root emergence (28.33±1.16) and maximum root length (3.40±0.67cm) was achieved on MS medium supplemented with 3mgl/l NAA. The in vitro grown plants were transferred to polycups containing a mixture of sterilized sand, soil and cocopeet (1:1:1) for hardening. The hardened plants were transferred to green-house conditions where they survived with 90% frequency.

Field studies were conducted to determine the potential for alterations in ion leakage and the intraspecific variation in ion leakage sensitivity of 20 wild sugarcane clones (Saccharum spontaneum L.) to enhanced ultraviolet-B (UV-B, 280-315nm) radiation in two consecutive years. The clones were collected from original sites with different altitude (from 0 to 1650 m) and latitude (from 18-37 oN). The supplemental UV-B radiation was 5.00 kJ m-2, simulating a depletion of 20 % stratospheric ozone. Across all clones tested in the present study, a significant change (P<0.01 or 0.05) in ion leakage for 11 in tillering, 14 in elongation and 15 in flowering in 2003, and for 9 in tillering, 5 in elongation and 5 in floweing in 2004 were observed. In general, intraspecific responses of ion leakage of wild sugarcane clones to enhanced UV-B radiation existed under field conditions for two consecutive years, alt though intraspecific difference in 2003 was more obvious than that in 2004. Wild sugarcane clones originating from lower latitude or high elevation were not necessarily the more tolerant to enhanced UV-B radiation.

Sugarcane cell cultures were obtained from callus formed on explants derived from young expanding leaves of two early maturing sugarcane varieties viz “CoJ83” and “CoJ86”. The cell cultures were varied with different arginine concentrations in the culture medium. For each cultivar, sucrose content with 20 μM arginine in the culture medium decreased from 3 to 5 days and then increased to 10 days after subculturing. Higher concentration of arginine in the culture medium (60 μM) decreased the sucrose content at different days after subculturing and thus significantly stimulated sucrose mobilization. The activity of sucrose synthase and sucrose phosphate synthase reached maximum while the activity of acid and neutral invertase was minimal in the culture medium with 20 μM arginine. Thus arginine at low concentration (20 μM) enables the cells to accumulate the higher level of sucrose. The optimum level of amino acids can be utilized to regulate the in vivo activity of sucrose synthase, sucrose phosphate synthase and invertase to achieve maximum sucrose accumulation in sugarcane storage tissue.

Isolates of Fusarium from rice, sugarcane and maize were identified as F. verticillioides, F. sacchari, F. proliferatum F. subglutinans, F. fujikuroi and F. oxysporum. The species were then characterized by restriction analysis of intergenic spacer (RFLP-IGS) using AluI, Eco88I, RsaI and XhoI. Twenty-five haplotypes were identified among the isolates of Fusarium which indicated high levels of variations. UPGMA cluster analysis was conducted to cluster the isolates and to estimate the intraspecific and interspecific variability. Isolates of F. fujikuroi from rice were clustered together with isolates of F. proliferatum from rice and maize with a similarity value of 88–100%. Isolates of F. verticilliodes from maize and sugarcane were clustered together with a similarity value ranging from 92–100%, and two isolates from rice formed another cluster. Isolates of F. oxysporum from maize and rice were clustered together with a similarity value ranging from 87–95%. Isolates of F. subglutinans from rice and maize, and F. sacchari from rice and sugarcane were also clustered together with a similarity value of 77–100%. Based on RFLP-IGS analysis, variability was observed within and between species of Fusarium from rice, maize and sugarcane and the technique could be use to complement morphological characterization and to determine genetic relationships between the species.

Izolaty Fusarium z ryżu, trzciny cukrowej i kukurydzy, określono jako F. verticillioides, F. sacchari, F. proliferatum, F. subglutinans, F. fujikuroi oraz F. oxysporum. Gatunki te scharakteryzowano przy pomocy analizy restrykcyjnej międzygenowego niekodującego odcinka genu (RLFP-IGS), wykorzystując AluI, Eco881, RsaI i Hoi. Określono dwadzieścia pięć haplotypów wśród izolatów Fusarium, co wskazywało na wysoki poziom zmienności. Przeprowadzono analizę skupień w celu pogrupowania izolatów i określenia intraspecyficznej interspocyficznej zmienności. Izolaty F. fujikuroi z ryżu zgrupowano razem z izolatami F. proliferatum z ryżu i kukurydzy wykazującymi podobieństwo 88–100%. Izolaty F. verticillioides z kukurydzy i trzciny cukrowej zgrupowano w ramach wartości podobieństwa od 92 do 100%, a dwa izolaty z ryżu tworzyły inne zgrupowanie. Izolaty F. oxysporum z kukurydzy i ryżu zgrupowano również razem, z wartością podobieństwa od 87 do 95%. Izolaty F. subglutinans z ryżu i kukurydzy i F. sacchari z ryżu i trzciny cukrowej zostały też zgrupowane razem i miały wartość podobieństwa 77–100%. W oparciu o analizę RLFP–IGS obserwowano zmienność w ramach i pomiędzy gatunkami Fusarium z ryżu, kukurydzy i trzciny cukrowej. Technika RLFP–IGS mogłaby być wykorzystywana w celu uzupełnienia charakterystyki mikroskopowej i do określenia genetycznych związków pomiędzy gatunkami.
