Abstract
Seed priming is a technique that can potentially facilitate rapid and consistent germination and subsequent plant growth. The present study investigates the effect of different seed priming treatments and processing times on germination and growth efficiency for the effective cultivation of Yard-long bean. Thirteen different primings were used to determine the stimulatory effect on the germination and yield performance of the Yard-long bean. The priming treatments included control (without priming); hydro priming for 12, 18, 24, and 30 h; halo priming (1% CaCl2) for 12, 18, 24, and 30 h; and halo priming (2% KNO3) for 12, 18, 24, and 30 h. Studies showing the highest level of germination (86.66%), germination index (35.69), seedling vigor index (1833.80), number of branches (7.20), and pod yields per plant (1836.00 g) were recorded from halo priming with 1% CaCl2 at 12 h treatment. Halo priming with 1% CaCl2 at 12 h is thus considered to be a compatible priming technique for the germination of seeds and a higher yield of Yard-long bean.

Influence of hydro- and osmo-priming on sunflower seeds to break dormancy and improve crop performance under water stress. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:13215-13226.

Abstract
This study explored the effects of two hydro- and osmo-priming durations (8 and 16 h) on growth and yield components of sunflowers (Helianthus annuus L.) under water stress. The pot experiment, performed under a rain shelter, consisted of 9 treatments replicated five times: unprimed seeds as control (C), hydro-primed seeds (T0), osmo-primed seeds in 10, 20, and 30% PEG-6000 (T1, T2, and T3, respectively). Severe water stress was applied for 12 days to all treatments at the beginning of the flowering stage. Statistical analysis revealed a very highly significant positive effect (p < 0.01) by all treatments on sunflower seed germination compared with the control. Moreover, primed seeds improved significantly for all growth parameters and yield components, but no significant differences were observed according to either priming technique or duration. The highest value of germination capacity, for fresh and dry biomasses, was obtained with PEG-primed seeds at 10% for 16 h. The grain number per anthodium and grain yield per plant from primed seeds were higher than those in the control (1.9- to 2.5-fold and 2.8- to 3.3-fold respectively). Under conditions of water stress, the proline content in primed plants was significantly higher than that in unprimed ones, with the exception of T3 treatment primed for 8 h. Soluble sugars and chlorophyll contents increased significantly with all applied treatments compared with the control. The study showed that the applied priming treatments improved germination characteristics in particular and increased growth and yield components for sunflowers under drought stress conditions.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 661:654-663. [PMID: 30682615 DOI: 10.1016/j.scitotenv.2019.01.188] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 01/15/2019] [Accepted: 01/15/2019] [Indexed: 05/17/2023]
Abstract
Microelements play important roles in improving crop productivity and quality. Two traditional methods of providing micronutrients are soil and foliar application, yet the cost involved and phytotoxicity risks poses a major challenge in most global agricultural areas. Nutri-priming represents thus a very promising and viable alternative to ensure that the plants' requirements for micronutrients are met. This paper explores the Mo-priming effects on the germination, growth and yield components of common bean (Phaseolus vulgaris L.). In order to accomplish this research objective, our study is divided in two phases. The first phase seeks to determine the effects of two durations (5 and 10 h) of Mo-priming on the germination parameters. Then, a greenhouse pot experiment was conducted with primed seeds showing better germination performance to assess the effects of Mo-priming on certain parameters related to biological nitrogen fixation and crop yield. Five seed pretreatments were studied, namely, 0, 0.025, 0.05, 0.1 and 0.2% of ammonium heptamolybdate ((NH4)6Mo7O24.4H2O). Unprimed seeds treated with or without the recommended dose through a soil application were used as controls. Hydropriming is sufficient to improve seed germination performance. However, 0.1% Mo-priming for 10 h improved the net CO2 assimilation rate, chlorophyll content and biological nitrogen fixation. Six times more nitrogen was fixed (65.8 kg ha-1) in these plants than in the controls. Additionally, grain yield increased by 115% compared to the negative control. Thus, compared to soil intake, nutri-priming was a very efficient experimental method.
