陆地棉光敏雄性不育系中9106是在中040029的后代中发现的突变体,它在长日照(河南安阳)条件下表现为彻底的雄性不育。以陆地棉乐土603、TM-1和海岛棉海7124为父本分别配置F2杂交组合发现中9106的雄性不育性状是受一对核基因控制的隐性性状。利用以全基因组测序为基础的分离群体群分法和以中9106×TM-1的F2群体进行的图位克隆,将中9106的雄性不育基因定位在D12染色体上QZD84和Q...
为了了解美国梾木花粉活力及萌发特性,采用扫描电镜技术和方差分析对13个美国梾木无性系花粉形态进行观测,并采用荧光显微技术和TTC染色法对无性系2号花粉萌发特性及花粉活力进行观察。结果显示:(1)不同无性系间花粉大小差异不显著,但外壁纹饰差异较大,极面沟距的变异系数最高且遗传最为稳定。(2)花序开花率为75%时花粉活力最高,整花4°C条件下短期保存花粉活力较高。(3)授粉后,多数花粉可在柱头上正常萌...

Morphological and physiological responses of 19 species of Triticum and its allied plants to NaCl concentration were studied. An interspecific difference was found in the changing patterns of RGR to N...
Effect of Mechanical Stimulation on the Growth of Amaranthus spp.
Water chestnut is an aquatic annual herb, and its fresh, edible fruit is a valuable crop. The huge variation in growth and yield of water chestnuts has not been well documented. In this study, the yie...
Cultivated buckwheats (Fagoprum spp.) show an easy grain shedding habit, which is known to cause heavy yield loss. In this study, the grain shedding habit was compared among diploids and tetraploids ...
Many of the recent additions to the US Cotton Germplasm collection are uncharacterized for common germplasm descriptors. The objective of this study was to evaluate a subset of cotton germplasm for th...
The present experiment investigated the effect of incubation temperature on growth of mycelium, spore germination and on the individual biotic effect (IBE) of Trichoderma harzianum, T. pseudokoningii ...
This study presents the ampelographic and molecular characterization of 44 grapevine cultivars. Ampelographic data were obtained during two vegetation periods using the latest version of the descripto...
A few temperate zone fruit species such as apples, pears, apricots and cherries dominate the fruit production in Eastern Anatolia region in Turkey, while the other species (e.g rose hip, hawthorn, sea...
Studies on growth and yield of Plumbago rosea and Plumbago zeylanica were undertaken in the College of Horticulture, Kerala Agricultural University, Thrissur during 1995 to 1998. Studies on growth...
Field experiments were conducted at Havza and Gelemen to evaluate the effect of different densities of Avena spp. and Alopecurus myosuroides Huds. on wheat cultivars Bezostaja and Kate-A-I. As expecte...
The aim of this investigation was to identify suitable parental lines of vetch (Vicia sativa spp.) from Turkish and ICARDA germplasm, with appropriate morphological and phenological characters, for ge...
