1.Restriction of vegetative growth to ensure flower initiation, defoliation to prevent the onset of dormancy, stimulation of adequate and uniform budburst, and avoidance of secondary dormancy are essential for success of non-dormancy culture.
控制营养生长、保证花芽分化,使树体避开休眠,促进足够多的芽整齐萌发,避免二次休眠的发生是无休眠栽培成功的4项重要保证。
2.The QTLs on chromosome 1 and 7 were detected in CSSL1 and CSSL2 populations simultaneously,QTL came from Asomonori, the moderate dormant cultivar,increased seed dormancy,and QTL from IR24,the weakly dormant cultivar,decreased seed dormancy. It can be deduced that there exist genes controlling seed dormancy at this region.
同时在两套CSSL群体上 ,分别检测到位于第 1、7染色体上位置相近且效应一致的休眠性QTL ,分析表明其所在的Asominori片段含对种子休眠性的增效基因 ,相应的IR2 4片段含有减效基因。
3.The main cause of its seed dormancy was afterripening of seed-embryo and seed-physiology. The mechanism of seed dormancy and germination was discussed. Seeds of two-year sand-storage treatment could be germinated up to 70% of surviving rate by means of freezing or GA+6-BA in 15 dyas, which shortened one year time of its seed dormancy.
珙桐种子繁殖和扦插繁殖的生物学特性研究,弄清了种子休眠的主要原因在于种胚形态后熟和生理后熟,探讨了种子休眠萌发机理.用人工低温冷冻或GA+6-BA处理,可使层积2年尚未萌发的种子70%左右在半月内迅速萌发出苗,缩短休眠期约1年.经不同处理的扦插试验,5%的插条可生根成苗.
4.A Study on Seed Dormancy Mechanism and the Method of Overcoming Dormancy of Acer Buergerianum Miq.
三角槭种子休眠机理及解除方法的研究
5.the dormancy of the seed could be affected by treating with different concentration of GA3, but the effect on breaking dormancy and accelerating germination was not obvious.
GA3对带壳种子的萌发有一定作用,但解除休眠、促进萌发的效果并不明显。
6.The higher degree dormancy alfalfas such as Millennium, Eureka, WL525HQ had the same growth habits, the same as the lower degree dormancy alfalfas such as AlfaKing, WL323ML, and Algonquin.
1、物候期生长规律与品种特性有关,休眠级较高的盛世、游客、WL525HQ的物候生长规律较一致,休眠级较低的苜蓿王、WL323和阿尔冈金的物候生长规律较一致。
7.Low temperature could improve to break dormancy There are three methods to determinate the end time of fruit trees bud dormancy: 7.2℃ low temperature model, Utah model and dynamic model.
低温可以促进打破芽休眠。 对果树芽休眠结束时间的计算有 3种方法 :7.2℃低温模型、犹他模型和动力学模型。
8.3.Non-fall-dormancy variety Eureka (FD8) obtained higher yields over fall-dormancy variety Derby(FD5)only under high temperature and high humidity environmental conditions.
EUREKA品种与DERBY品种相比 ,突出的产量优势表现在高温高湿、高温干旱的不利气候条件期间 ;
9.And chemical treatment such as hormones, organic and inorganic chemicals, and using the comprehensive methods to break dormancy is more effective than a mono-treatment for those seeds that induced dormancy by complicated factors.
对一些属综合休眠类型的植物种子,则采用综合法来解除休眠较单一方法效果显著。
10.Changes of H2O2 content,activities of antioxidant enzymes and the respiration rate of flower buds treated with CaCN2 were similar to those treated with SA in early dormancy and deep dormancy stage.
②在初休眠期和深休眠期,石灰氮和水杨酸处理的花芽H2O2含量、抗氧化酶和呼吸速率的变化趋势相似。
