Aquatic macroinvertebrates have a close relationship with associated floating macrophytes, especially with the roots. The plant root mass is an environment favorable to the development of the macroinvertebrate fauna, supplying both food resources and refuge against predators. The present study aimed to analyze the structure of the macroinvertebrate community associated with the roots of Eichhornia azurea (Sw.) Kunth (Pontederiaceae) in a lake marginal to a tropical river. Sampling was performed quarterly in three stands of E. azurea.

Laggera tomentosa Sch. Bip. ex Oliv. et Hiern (Asteraceae), an endemic Ethiopian medicinal plant, is traditionally used to treat various ailments. Previously, the chemical constituents of the essential oil (EO) of its leaves and inflorescence were documented. However, no data about the chemical compositions of other parts of the EOs of the plant have been reported to date. Moreover, there are no previous biological activity reports on any parts of the EOs of this plant.

The essential oils (EOs) constituents have trade importance due to their bioactivities. In this research, the essential oil of the roots of Chrysopogon zizanioides (L.) Roberty cultivated in Giresun was obtained by hydrodistillation. Then, the chemical composition and biological activities of Chrysopogon zizanioides root essential oil (CEO) were studied. Thirty compounds were identified by gas chromatography-mass spectrometry (GC-MS) and the major compounds were determined as isobutyl-angelate (11.15%), α-muurolene (10.56%), α-cedrene (8.42%), α-patchoulene (8.

Three Trichoderma isolates (THDU-1, THDU-2, and THDU-3) were isolated from the root zone area of healthy bananas on the farm in Ba Thuoc district, Thanh Hoa province. All of these isolates showed high inhibitory activity against soil borne diseases Rhizoctonia solani and Sclerotium rolfsii. Our study proposed a protocol of Trichoderma mass multiplication using rice media based on solid substrate fermentation (SSF) to produce commercial product of Trichoderma.

Population fluctuations of root-knot nematode, Meloidogyne incognita during crop season were studied on cucumber in two poly-houses of different locations. For the observations plant and soil samples were taken at fifteen days intervals throughout the crop season up to 120 days. Results showed that lowest 2.60 and highest 74.00 galls/5g roots of cucumber found at 15 and 120 days after sowing. No egg masses observed just 15 days after sowing of crops due to root-knot nematode complete their entire life cycle within 25 to 30 days.

The present crisis has emphasized human dependency on bamboo with quality planting materials. A study focused on the effect of the different concentrations of IBA (0 ppm, 100 ppm, 200 ppm, 300 ppm) on the sprouting and rooting behaviours of 5 bamboo species viz. Dendrocalamus strictus, Bambusa vulgaris, B. nutans, B. tulda and B. bambos found in coastal Odisha in order to get an idea for mass multiplication and biomass production to meet the multifarious demands of bamboo based sector.

The performance and water use efficiency (WUE) of Chrysanthemum var. Marigold was evaluated under two moisture regimes, i.e., 100 % FC and 70 % FC imposed and maintained using gravimetric method. At 100 % FC, the plant height (30.33 cm), average plant spread (38.21 cm), number of primary branches/plant (5.67) and secondary branches/plant (4.67), number of leaves/plant (71.67), number of flowers/plant (136.75), average weight of individual flowers (7.21g), RWC (94.29%), root: shoot ratio (0.42), total fresh bio mass (153.09 g), flower yield (881.67 g / plant) and shelf life of 7.

Penetration was not affected by temperature but, migration and postpenetration inside the root tissue were influenced by temperature. At 27±1°C, M. incognita second stage juvenile (J2) took 5 days to reached stele region followed by 31±1°C and 23±1°C (7 days) while, at 21±1°C, it took 10 days. Multiplication of M. incognita was greatly affected by temperature. Maximum number of galls per root system (119.6), number of egg masses per root system (275.2), number of eggs per egg mass (343.6), final nematode population (1335.2) and reproduction factor of nematodes (2.

Arbuscular Mycorrhyzae Fungal (AMF) spores were obtained through mass multiplication in maize (in a previous experiment) as a host crop. A study was conducted to test the effectiveness of AMF in rice as host, with three levels of P2O5 (0, 20 and 40 kg/ha) under submerged condition. By reducing levels of P2O5 to 50 % (20 kg/ha) comparable plant biomasses were recorded (P < 0.05) under AMF inoculation with that of highest level of P2O5 (40 kg/ha) with or without AMF inoculation.

A study on influence of different doses of Benzyl Adenine (BA) combined with constant level of Naphthalin acetic acid (NAA) on callus induction, shoot multiplication, and rooting of Kew pineapple was conducted. Early callus response was observed in treatment concentrations of 2mg/l BA with 2mg/l NAA and 3mg/l BA with 2mg/l NAA. Treatment 2mg/l BA with 2mg/l NAA was resulted to replicate the maximum number of shoots (22.71 at 90 days) significantly among the treatments. Shoot length was most enhanced by 0.5 mg/l BA with 2 mg/l NAA (8.09 cm at 90 days) dose.
