多年生苜蓿以根的形式越冬,因此,苜蓿的抗寒性以及成功越冬的关键在于其根部的抗寒性。在没有叶绿体结构不能进行光合作用的根部,呼吸作用是维持根部细胞生长所需能量ATP的唯一途径。新疆农业大学刘美君副教授团队选用不同秋眠级的新牧4号(秋眠级为2) 和甘农5号(秋眠级为8) 的紫花苜蓿为试验材料,研究发现,低温显著影响了苜蓿根系细胞呼吸代谢,细胞线粒体电子传递链复合体复合体IIIII和IV受抑明显致使氧...
High seedling vigor can improve the ability to compete against weeds and flooding at the seedling stage and is essential for the direct seeding of rice. Early shoot length is an important performance ...
Leaf rolling and discoloration are two chilling-injury symptoms that are widely used as indicators for the evaluation of cold tolerance at the seedling stage in rice. However, the difference in cold-r...
Why are there so many species of plants? Why do some plants thrive, while others don't?Ecologist Noelle Beckman of Utah State University and her colleagues explore these questions in new fin...
Soil moisture and compaction are important factors for growth and development of plant root. This study was conducted as a nested design with two factors and three replications to investigate the beha...
To determine stem rust resistance genes of wheat varieties in Yunnan province, 11 Chinese strains of Puccinia graminis f.sp. tritici with different virulence and 1 artificial mutant strain were used i...
Phytotoxic effects of aqueous extracts of walnut leaf were studied on germinating seeds and early seedling growth of mustard (Brassica campestris cv. Karanti) under western Himalayan agri-silvi system...
This study evaluated the effects of three A. brasilense strains (i.e. Sp7, Sp7-S and Sp245) on the early seedling growth of lettuce, tomato and cucumber. Seeds were inoculated by soaking and drenching...
The level of occurrence of black point, the spectrum of fungal species and damage to wheat seedling vigour associated with it were assessed during 2003 and 2004 in the Slovak Republic. The incidence...
In contrast to the extensive understanding of seed mucilage biosynthesis, much less is known a bout how mucilage is biodegraded and what role it plays in the soil where seeds germinate. We studied see...
Background: The responses of plant seeds and seedlings to changing atmospheric nitrogen (N) deposition and precipitation regimes determine plant population dynamics and community composition under glo...
The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory ...
In two independent experiments set up in the greenhouse the seedling resistance to Stagonospora nodorum blotch was investigated in 92 varieties, breeding lines and genotypes with a known genetic backg...
The effect of garlic extract containing bioactive allicin on the germination and subsequent seedling vigour of pathogen-infested wheat seeds, was tested. The first aim was to characterize the antifung...
Seasonal changes in water relations parameters, dry weight fraction (DWF), and root growth potential (RGP) were examined for Anatolian black pine [Pinus nigra Arn. subsp.
