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...
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.
Soil salinity threatens initial stages of emergence and early seedling growth in cool season grasses, although it may be tolerant in its adult stages. Today, seed priming has been known as an effectiv...
Effects of seed size and osmotic stress on germination and seedling growth of fifty-five oat genotypes obtained from Europe, North and South America, Asia and Oceania were investigated. Small, medium ...
Reactive oxygen species (ROS) play an important role in seed germination. Although hydrogen peroxide (H2O2), a type of ROS, enhances the germination rate of various plant seeds, little is known about ...
The purpose of this study is to develop a planting machine for rush seedlings. In rush seedling production systems, the use of plug seedlings has been widely popularized in Japan. However, the plantin...
A “rice nursling seedling” is the youngest stage of rice seedling transplanted by machine in Japan, and is defined as a seedling of 2 to 3 plant age in leaf number. However, changes in morphological a...
For the introduction of low temperature germinability (LTG),seed longevity and accelerated coleoptile growth derived from foreign varieties to Japanese elite varieties to breed rice varieties for dire...
Five rhodesgrass (Chloris gayana Kunth) cultivars (Asatsuyu, Hatsunatsu, Katambora, Osumi-5, and Osumi-7) were evaluated for forage yield in a 3-year field experiment in the main island of Okinawa loc...
Light quality and quantity of the environment, where lettuce seedlings were grown, affected the mesophyll tissue and the shoot formation in cotyledons excised and cultured in vitro. When cultured on M...
Emergence and establishment of seedling of paddy rice sown into flooded soil are poor but promoted when seeds are coated with O2 generator CaO2. It has been commonly understood that this is because C...
The variation of seedling growth, which may affect seedling salt tolerance, of 12 rice cultivars was examined based on the pattern of seedling fresh weight histogram. Some cultivars showed a normal di...
