Root pressure was measured continuously over spring in eight clonal kiwifruit rootstocks selected from seven Actinidia species (A. chrysantha, A. deliciosa, A. eriantha, A. hemsleyana, A. kolomikta, A. macrosperma, A. polygama), using pressure transducers and miniature compression fittings. Rootstocks that promoted scion vigour developed root pressures up to 0.15 MPa before or during scion budb...

The experiment was conducted in the Ecology Field, Arid Forest Research Institute, Jodhpur (Rajasthan), India during 2020-21 to explore role of insect pollinators fruit setting P. cineraria. For conducting experiments one branches selected trees covered with a mesh bags exclude floral visitors (pollinator exclusion). other branch kept uncovered for time (open pollination). Our findings revealed...

Nanotechnology is a novel and emerging approach that can be utilized in the agriculture sector for biotic abiotic stress management, disease detection, nutrient absorption. Various metal oxide nanoparticles such as zinc, titanium, silicon oxides were found to have positive effect on seed quality attributes various crops. Therefore, study was carried out chickpea (Cicer arietinum L.) with object...

Mature seeds of many crop species contain substantial amounts soluble carbohydrates, including raffinose family oligosaccharides (RFOs) and cyclitol galactosides (Gal-C). These substances are hydrolysed by α-D-galactosidase (EC 3.2.1.22) during the early stages germination, providing metabolic energy for germination process. A decrease or inhibition activity can significantly reduce rate. This ...

environmental conditions including metrological parameters (precipitation, temperature, humidity and etc.) various stresses and nutrition, could affect  germination and  seeds vigor during of development, ripping and leven after harvesting of soybean seed. for this, experiments of completely randomized design ( as nested)by four replications were performed in seed laboratory of gorgon universit...

Seed priming with zinc increases the seed germination and seedling growth of many crops. The present study aimed to investigate effect different levels sources on barnyard millet variety MDU1. A experiment was conducted various Zn concentrations viz., T1- Non-primed seeds (control); T2-water priming; T3-GA3 T4-T6: 0.10%, 0.25% & 0.50% ZnSO4 ; T7- T9: EDTA; T10-T12: citrate experimental desi...

Soil physical and chemical characteristics play a key role on vine growth yield. The soils of South Uruguay display high content montmorillonite or illite. proportion these minerals deserves special attention as they influence the soil structure its hydrological properties. present study was conducted in 1.1 ha vineyard this region (Canelones), characterized by heterogeneity plant vigour. It ai...

It was evaluated the damage caused by Bruchus pisorum on the germination ability of pea forage cultivars. Result of damage in seeds with parasitized larva was a significant decrease of the germination by 16.4% percentage points, the length and weight of primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and 14.1%, the vigor index of primary radicle and plumule by 32.5 a...

The basal ganglia are known to be involved in the planning, execution and control of gripping force and movement vigour. Here we aim to define the nature of the basal ganglia control signal for force and to decode gripping force based on local field potential (LFP) activities recorded from the subthalamic nucleus (STN) in patients with deep brain stimulation (DBS) electrodes. We found that STN ...
