1)seed vigor index种子活力指数 1.During seed development and maturation,strong negative correlations were observed between ABA content of seed coat andseed vigor index,as well as germination rate.随着种子的成熟,种子对外源ABA的敏感性逐渐降低,种皮ABA含量与种子活力指数呈极显著负相关,与出苗率呈显著负...
Seedling growth uniformity and seed vigor index were greater from both coatings with 30 and 40% soy flour than the noncoated control for both crops. The coating treatment with plant-based proteins resulted in the greatest biomass compare to the control. Proteins applied in the seed coating can ...
Under the optimal conditions, the germination energy, germination rate and seed vigor index were enhanced, cell inclusion exosmosis of bottle gourd seeds were decreased, whereas the activities of POD and SOD were increased.关键词: PEG Bottle gourd seeds Seed vigor Seed priming ...
This webinar will walk the participant through the primary standard germination and vigor tests used to evaluate seed corn quality. The principles of each test will be discussed, along with baseline quality levels and interactions that may occur. Two standard germinat... December 2-5, 2014 Cara...
Therefore, timely harvest is of importance for hybrid rice to achieve maximum seed viability, vigor and yield. In this study, the optimum harvesting time based on seed vigour was ranged from 17 to 23 DACAP for the production of high vigour hybrid rice seeds. Fu et al.11 reported that ...
In this paper the wet aging rice seeds were treated with HVEF.The effect of HVEF on the seed vigor was studied.The results showed that the germination rate,germination velocity,vigor index and the dry weight of seedings were significantly increased after treatments.The root vigor,content of ch...
In order to study the effect of seed size on seed vigor index of wheat, a factorial experiment based on a completely randomized design was arranged with four replications at the laboratory. The experiment had two factors. The first factor consisted of 13 wheat genotypes and the second factor ...
(Jagadish, 1993). Seed germination parameters ofEucalyptus citriodora,namely viability percentage, germination percentage, germination energy, germination speed,moisture content, seedling fresh and dry weights, length of seedling, shoot and root length of seedling, and seedling vigor index (I and II)....
杂种优势 heterosis;hybrid vigor 两个基因型不同的个体杂交产生的杂种一代,在个别性状或综合性状上,比其双亲优越的遗传现象。 杂种劣势 negative heterosis 两个基因型不同的个体杂交产生的杂种一代,在个别性状或综合性状上,反而不如亲本的遗传现象。 杂种衰退 hybrid breakdown ...
Analysis of variance of laboratory data showed that hydropriming significantly improved germination rate, seed vigor index, and seedling dry weights. However, germination percentage for seeds primed with KNO3 and non-primed seeds were statistically similar, but higher than those for NaCl priming. ...
