Phelipanche aegyptiaca Management with Glyphosate in Potato  [PDF]
Mustapha Haidar, Elie Shdeed
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.616256
Abstract: Two years field and greenhouse studies were carried out to evaluate the efficacy of sub-lethal doses of glyphosate (Round upR), ammonia gas, phosphoric acid and sulfuric acid against Phelipanche aegyptiaca in potato. Results showed that sequential application of sub-lethal doses of glyphosate at all tested rates significantly reduced P. aegyptiaca shoot number and shoot dry weight. While, the use of ammonia gas, phosphoric acid and sulfuric acid had no significant effect on the total level of P. aegyptiaca infection as compared to the control. The best results considering both P. aegyptiaca control and selectivity in potato were obtained by sequential application of sub-lethal doses of glyphosate at 60 and 80 g·ai·ha-1. Sequential application of glyphosate at 60 g·ai·ha-1 reduced P. aegyptiaca infection by 100% after 100 days after potato emergence (DAPE). Except for sequential application of glyphosate at 60 and 80 g·ai·ha-1, all tested rates enhanced the maturity rate of potato plants and decreased the number of marketable potato tubers.

Abstract: The decoction of Balanites aegyptiaca, a plant used in traditional medicine in Africa for many diseases, possesses anticonvulsant and sedative activity in mice. This decoction protected mice against strychnine- and pentylenetetrazol-induced seizures. But Balanites aegyptiaca decoction had no effect against picrotoxin-induced seizures. In the other side, the decoction of Balanites aegyptiaca potentiated sleep-induced by diazepam. The total sleep time of the control group was multiply by 4 in the presence of the decoction at a dose of 1000 mg /kg (from 12 to 59 min). With these effects, the decoction of Balanites aegyptiaca L. seem to posses sedative and anticonvulsant properties that might explain its use as a traditional medicine for epilepsy in Africa.
云南红豆杉人工林萌枝特性  [PDF]
生态学报 , 2013,
Abstract: 萌枝是许多木本植物维持种群稳定和延续的重要机制之一。通过对云南红豆杉人工林萌枝情况的调查,分析了云南红豆杉萌枝特征及其对生长的影响。结果表明:(1)云南红豆杉萌枝现象明显,萌枝率达到88.1%,萌枝类型有树基萌枝和树干萌枝两种,其中树基萌枝是最主要的类型,有树基萌枝的个体达到了总株数的80.0%,树干萌枝率仅为39.6%,约为树基萌枝率的一半,两种萌枝都有的比率为31.5%;(2)云南红豆杉的树基萌枝数量与树高呈正相关关系,与地径呈负相关关系,而树干萌枝数量与树高和地径都没有显著的相关关系。总萌枝数量与树高及地径的相关关系与树基萌枝的一样,但相关性略低。(3)树基萌枝和树干萌枝都会影响云南红豆杉枝叶的空间分布格局,但从植株总体上说,它们对云南红豆杉的枝叶生长量没有显著的影响。
Transformation and regeneration of the holoparasitic plant Phelipanche aegyptiaca

Abstract: Here we demonstrate that transformation of Phelipanche aegyptiaca is achieved by infection of 3 month-old in vitro grown P. aegyptiaca calli with Agrobacterium rhizogenes harboring the yellow fluorescent protein (YFP). Four months later, YFP-positive regenerated calli were inoculated onto tomato plants growing in a minirhizotron system. Eight days after inoculation, transgenic parasite tissue formed lateral haustoria that penetrated the host and could be visualized under UV illumination through intact host root tissue. YFP-positive shoot buds were observed one month after inoculation.This work constitutes a breakthrough in holoparasitic plant research methods. The method described here is a robust system for transformation and regeneration of a holoparasitic plant and will facilitate research on unique parasitic plant capabilities such as host plant recognition, haustorial formation, penetration and vascular connection.Parasitic weeds belonging to the genera Orobanche and Phelipanche have lost through evolution their autotrophic way of life, switching from photosynthesis to obtaining their resources by parasitizing other plants. Parasites capture host water and nutrients through a specialized organ, the haustorium, which invades the host root and connects with the host vascular system [1-3]. Phelipanche aegyptiaca (syn. Orobanche aegyptiaca) is an important parasitic weed attacking many crops in Asia and the Middle East. Conventional control based on cultural methods, herbicides, or host breeding for parasitic plant resistance, have not attained complete success due to several factors associated with the parasite life cycle, including high fecundity (hundreds of thousands of seeds per parasite), seed longevity in the soil, the subterranean location of the young parasite that effectively hides it from the farmer, the tightly coordinated parasitic and host life cycles, and the scarcity of sources of resistance in most affected crop species [4-6].

Abstract: Various pharmacognostical parameters including macroscopy, microscopy, Physiochemical and behavior of powdered drug on treatment with different chemical reagents were studied on the stem bark of Balanites aegyptiaca Linn. Delile. (Family- Balanitaceae).The successive extraction of plant bark was undertaken by using various solvents of increasing polarity and the extracts thus obtained were subjected for phytochemical analysis. The phytochemical investigation revealed the presence of alkaloids, glycosides, flavonoids, and phenolic compounds mainly. These preliminary data may be helpful in developing the standardization parameters of Balanites aegyptiaca Linn. Delile stem bark.

Abstract: There is strong evidence across the drylands of Africa that local communities have utilized Indigenous Fruit Trees (IFTs) including Balanites for generations. IFTs have however, received limited recognition from research and development community. It is now widely accepted that IFTs research needs to embrace local knowledge since this can be a useful resource in solving local problems and contribute to meaningful development. This study explored local use and management of the Balanites aegyptiaca among two contrasting dryland communities in Uganda. A survey involving 150 respondents was conducted using a semi-structured questionnaire. Focus group discussions and key informant interviews were conducted to capture detailed information on various aspects of Balanites use and management. The results revealed a wealth of information on local use and management of B. aegyptiaca tree and its products. Besides being a market commodity, several uses of the tree products were reported, especially among women and children. Contrary to its early reference as famine food, B. aegyptiaca products were used by most households. The young leaves and ripe fruits were regarded as dependable dry season food sources in both years of food scarcity and plentiful harvest. However, institutional arrangements for management of Balanites and other IFTs are weak and trees are increasingly being cut for fuelwood. There is a need to build on the local peoples knowledge, especially on processing of products so as to realise increased contribution of Balanites to rural livelihoods in the drylands of Uganda and other areas where the species grows.
木本植物萌枝生态学研究进展  [PDF]
应用生态学报 , 2005,
Abstract: 综述了萌枝的生物学特征、个体生活史策略、生物地理学特征,以及对种群和群落特征的影响.已有的研究虽然在干扰与萌枝关系、萌枝生活史策略等领域取得了众多成果,但生态学意义远未揭示清楚,尤其是萌枝对种群、群落结构和动态的影响还需要深入探索.我国在重视萌枝生态理论研究的基础上,应加强理论和植被恢复及生态系统管理实践相结合的研究.
