“…Generally, seedlings from primed seeds achieved a higher emergence percentage, and earlier canopy expansion than unprimed control seedlings, resulting in greater shoot and root weights. These results agree with those of Wolfe and Sims (1982) on tomato and Saleh et al (1996) on pepper.…”

Artichoke seeds germination shows variation in germination percentage and speed with non-uniform seedlings. Two labratory and nursery experiments were carried out during seasons of years 2011/2012 and 2012/2013 to investigate the enhancement role of seed priming agents on seed germination and seedling behvior of locally produced seeds of globle artichoke Cynara scolymus L (green globe CV.).Seeds were primed in 8 different priming agents (PEG 8000, KNo 3 , K 2 HPO 4 , Na 2 SO 4 , NaCl, MgSO 4 , KCl, or Mannitol.) plus the control treatment (without priming). Both germination under laboratory conditions and emergence under nursery conditions were evaluated.Germination percentage, coefficient of velocity and germination performance index were significantly increased as a result of seed priming treatments. KNO 3 , PEG and mannitol were found to be the best treatments in this regard. Priming artichoke seeds in different priming agents reduced mean germination time and time required to reach 50% germination. KNO 3 , PEG and mannitol significantly improved the seedling characters in terms of seedling length and seedling fresh and dry weights as well as amylase activity. However, K2HPO4 was the best treatment in activating the peroxidase enzyme.Emergence and subsequent growth of seedling in trays responded positively to seed priming and KNO 3 was the suprior in enhancing emergance percentage and seedling growth in terms of seedlings height, number of leaves and dry weights of shoots and roots.It could be recomended that, priming local produced artichoke seeds in KNO 3 , PEG and mannitol will enhance seed germination and subsequent seedling growth which in turn will lead to using seed as a new method for propagtion and multplication under Egyptian condition and subsequently the cultivated area with artichoke will increase.

“…Los mejores resultados se obtuvieron con el sustrato tierra de encino, en el cual se tuvo el mayor porcentaje de germinación y las plántulas presentaron mayor altura y mayor acumulación de materia seca. Porcentajes de germinación bajos y erráticos en semillas de chile han sido atribuidos al contenido de sustancias inhibidoras en sus cubiertas (Saleh et al, 1996). Los tratamientos a las semillas con alguna solución de sales de potasio pueden incrementar el porcentaje de germinación (Macit, 1981).…”

Calidad De Plántulas De Chile ‘Poblano’ en La Sierra Nevada De Puebla, México

et al. 2011

La producción de chile ‘Poblano’ (Capsicum annuum L.) en la Sierra Nevada de Puebla ha disminuido en los últimos años como consecuencia de la mala calidad de las plántulas, entre otros problemas. El objetivo de este trabajo fue identificar técnicas de manejo que permitan mejorar la calidad de las plántulas producidas en almácigos a cielo abierto, mediante el incremento de su sanidad y vigor, y evaluar la eficiencia de la tierra de encino de la región como sustrato para la producción de plántulas en invernadero. Como variable de respuesta se midió porcentaje de germinación, altura, peso seco de raíz y peso seco de la parte aérea, en plántulas obtenidas mediante la combinación de sustratos, variedades, dosis de fertilización y desinfestación de semillas, en invernadero; en campo se probó la combinación desinfestación del suelo, variedades, niveles de fertilización y desinfestación de semillas. Los resultados en invernadero indicaron mayor porcentaje de germinación, altura y acumulación de materia seca en plántulas desarrolladas en tierra de encino que en aquellas producidas en la mezcla de “peat moss” y tierra de encino. En campo la desinfestación del suelo con agua caliente tendió a reducir el porcentaje de plántulas enfermas; en invernadero y campo la altura de plántula y la acumulación de materia seca se incrementaron al hacer dos aplicaciones de 16N-40P-13K más una aspersión de fertilizante foliar. Es posible mejorar la calidad de la plántula que se produce en almácigos de invernadero mediante una adecuada fertilización, con el uso de tierra de encino como sustrato, en lugar de la mezcla de “peat moss” más tierra de encino, mientras que en almácigos de campo conviene desinfestar el suelo con agua caliente porque tiende a reducir la incidencia de enfermedades.

“…Some authors find that a specific ion or salt is not essential in priming pepper seed [58], and other horticultural crop species [17]. Nitrate enhanced germination and seedling establishment rates, under adverse conditions, of onion [59] tomato and asparagus [16], melon [60], watermelon [61,62], husk tomato [39] and pepper [63][64][65][66]. Our results also indicate that nitrate-containing salts are more efficient than nitrate-free salts at promoting germination (except breaking dormancy) of primed seeds.…”

The effects of different priming techniques were evaluated to improve the dormancy and germination of wild seeds of “Piquín” chili pepper. Three experiments were designed for pre-sowing treatment of seeds: a) chemical seeds digestion; b) halopriming (with K+ or NH4+ of NO3-, SO42- or Cl-) at different priming times (24, 48 or 72 h) and osmotic potential (-5, -10 or -15 atm) and c) previously selected halopriming (KNO3 and NH4NO3) + Gibberellic acid (GA3, at 100 or 200 ppm) were tested. Digestion treatments did show a negative effect on seed germination. Recommended values of osmotic potential (Ψs), to improve Piquín chili seed germination, must be between -10 and -15 atm (-1.0 and -1.5 MPa) and the priming time must be between 48 and 72 hours. Priming techniques can considerably reduce Capsaicinoids content on seeds, improve dormancy, seed germination performance, and increase the rate and uniformity of seedling establishment. KNO3 and secondly GA3 treatments may improve rapid and uniform germination and seedling emergence. The results provide basic information to develop guidelines for commercial establishment of Piquín pepper crops.
