4 授粉树配置及授粉疏果问题 为提高大樱桃的经济效益,今后建园不必再用酸樱桃作授粉树,最好选用果实经济性状好、花粉量大、授粉好的大樱桃品种,特别是白花授粉好的,现已认定的先锋、拉宾斯、雷尼等,都是很理想的授粉品种。从乌克兰引进的5个专利大樱桃品种奇好、早大果、胜利、友谊、宇宙,任何3个品种组合都可以解决互相授粉问题。 相似文献

甜樱桃不同品种生长结果习性调查 总被引:3,自引:0,他引:3
以"红灯"、"布鲁克斯"、"红宝石"、"斯得拉"、"拉宾斯"、"先锋"6个甜樱桃主要栽培品种为试材,对树体生长状况、结果枝类组成、总芽数量、花芽数量、果实经济性状进行调查。结果表明:不同品种树高、冠径、干径存在差异;供试品种均以花束状果枝结果为主,"红宝石"、"斯得拉"、"拉宾斯"和"先锋"花束状果枝的比例分别为84.9%、83.3%、76.8%、83.3%,显著高于"红灯"和"布鲁克斯";不同结果枝类总芽数量和花芽数量不同;"先锋"和"红灯"总芽数量及花芽数量均显著多于其它品种;果实经济性状因品种而异,"先锋"平均单果重较大,"布鲁克斯"和"红灯"可溶性固形物含量较高。 相似文献

甜樱桃花芽分化后期特征观察 总被引:1,自引:0,他引:1
通过品种比较、地区比较和人工环境模拟3个关联的试验设计,观察甜樱桃从落叶后至谢花后的花芽分化发育的特征,探求其南引试栽、结实困难的原因。结果表明,郑州的早红宝石、红灯和拉宾斯,烟台、郑州和金华的红灯,以及花芽分化期置于露地和日光温室中的早红宝石在多个物候期阶段的最终分化发育的基本特征一致。因此,造成甜樱桃南引试栽、结实困难的主要原因可能与生长季的花芽分化无关,不能仅限于与花前高温引发的胚珠、胚囊发育不良有关,低温累积量不足也是不可被忽视的因素。 相似文献

Promalin (6-benzyl amino purine plus gibberellins A4 + A7) increased spur and lateral shoot development when applied in paint to one-year-old wood of several sweet cherry cultivars. Although applications close to bud burst were slightly more effective, good responses were obtained at all timings during the 10-to 18-day period from bud swell to bud burst. Brown paint was a more effective carrier for Promalin than white paint. Localized increases in axillary development were possible as the response to Promalin occurred at and above, but not below, the treated area. Increased spur and lateral development caused by Promalin caused marked increases in flowering and cropping in subsequent seasons. Sprayed applications of Promalin after bud burst had no effect on axillary development and caused a reduction in return bloom. Despite variation between cultivars in response to painted applications, the use of Promalin offers new prospects for the management of young cherry trees. 相似文献

The effectiveness of two commercial formulations of gibberellin (GA) and benzyladenine (BA) for reducing foliar chlorosis on Easter lily (Lilium longiflorum Thunb.) was compared. On a per liter basis, plants were sprayed with 0, 100, 200, or 400 mg (BA equivalent) of Accel (GA4+7:BA of 1:10) or Promalin (GA4+7:BA of 1:1) when the crop leaf area index (LAI)=3. One group of plants was sprayed with 100 mg of Accel or Promalin (BA equivalent) per liter twice: once at LAI=3 and again 3 weeks later. Plants were harvested when the largest flower bud on each plant measured 13 cm in length, stored for 0 or 3 weeks at 2.5°C in the dark, and then moved into a post-harvest evaluation room at 21°C, where foliar chlorosis was monitored for 3 weeks. Senescence of some lower leaves on plants in every treatment was evident at harvest, and incidence of senescence increased during the 21 days of post-harvest evaluation. Cold storage increased the number of leaves senescing during the subsequent evaluation period. Application of Promalin or Accel significantly reduced leaf senescence compared to that of untreated plants. At harvest, 21% of the leaves on untreated plants were senescent, while plants treated with Promalin or Accel averaged 3 or 9% senescent leaves, respectively. Following 7 days of post-harvest evaluation, Promalin was more effective in preventing chlorosis than Accel at the 400 mg l−1 (BA equivalent) level. Following 14 or 21 days of post-harvest evaluation, Promalin was more effective than Accel for the 100 mg l−1 2× and 400 mg l−1 (BA equivalent) treatments.Plants in all Promalin and Accel treatments were taller than untreated plants 1 week after sprays were applied. At harvest, plants sprayed with Promalin were between 6 and 14 cm taller than untreated plants, but those treated with Accel were the same height as untreated plants.Neither Promalin nor Accel influenced the occurrence of malformed or aborted flowers in this study. However, cold storage significantly increased the number of plants with aborted buds and malformed flowers. Unstored plants averaged 0.16 aborted buds and 0.02 malformed flowers each, while those stored 3 weeks averaged 0.51 aborted buds and 0.18 malformed flowers each. 相似文献

甜樱桃品种‘拉宾斯’与‘雷尼’均为S1S4基因型。调查其自花结实率,‘拉宾斯’为31.3%,表现自交亲和;‘雷尼’为0,表现为自交不亲和。将‘拉宾斯’与‘雷尼’相互授粉,‘拉宾斯’为父本时表现亲和,反之不亲和,推断‘拉宾斯’的自交亲和性由花粉侧突变导致;调查花粉萌发率,‘拉宾斯’为58.08%,‘雷尼’为57.82%。鉴定‘拉宾斯’自交后代及其与‘雷尼’杂交后代的S-RNase的基因型,发现所有后代中均出现S4基因型,部分后代中出现S1基因型,证明‘拉宾斯’花粉育性是正常的,其亲和性可能是由S4基因座上花粉侧的基因突变导致。测序发现‘拉宾斯’花粉SFB4′在911 bp处有4个碱基缺失。分析‘拉宾斯’花粉SFB4′与花柱S4-RNase的连锁性,发现两者连锁率为100%。以‘拉宾斯’为父本的带有SFB4′的杂交后代的自花结实率为23.3%~61.4%,表现自交亲和,说明来源于‘拉宾斯’的SFB4′基因与自交亲和性有关。RT-PCR及测序显示‘雷尼’SFB4与‘拉宾斯’SFB4′均能正常转录,但4个碱基缺失导致其C端翻译提前终止,原核表达SFB4和SFB4′蛋白发现SFB4略大于SFB4′,推测是由于SFB4′的翻译提前终止导致的。以上结果表明:‘拉宾斯’的自交亲和性可能是由花粉侧SFB4′C端的氨基酸缺失导致,该缺失可能使其丧失了与S-RNase的识别能力。 相似文献

大樱桃褐斑病病原菌鉴定与田间流行动态研究 总被引:3,自引:0,他引:3
【目的】为有效防控大樱褐斑病,【方法】采用传统形态学鉴定方法、单胞分离法和柯赫氏法则,开展了樱桃褐斑病原菌、田间流行学和品种抗病性研究。【结果】研究结果明确了褐斑病病原菌为核果钉孢菌(Passalora circum-scissa)。田间流行动态研究结果表明,6月下旬或7月初始见褐斑病发生,7月下旬进入发病高峰,与降雨程度关系密切;7月下旬或8月初检测到褐斑病菌孢子,8月中旬至9月中旬为孢子释放高峰期。不同大樱桃主栽品种褐斑病发生程度差异较大。明确了烟台樱桃褐斑病初次防治关键期为6月中旬。【结论】研究结果为有针对性地田间防控大樱桃褐斑病提供了理论依据。 相似文献
