Sexual crossing between two genetically female plants and sex genetics of kakrol (Momordica dioica Roxb.)     

Mohammad Amir Hossain  Mahbubul Islam  Mohammad Ali 《Euphytica》1996,90(1):121-125

Summary Application of 200 to 800 mg/l silver nitrate (AgNO₃) to the female kakrol or teasle gourd (Momordica dioica Roxb.) plant was effective for inducing hermaphrodite flowers. Pollen grain viability of the hermaphrodite flowers was as high as that of normal male flowers. Crossing among female genotypes of different fruit morphotypes, taking pollen from the induced hermaphrodite flowers, produced fruits and seeds. Sex of hybrids between female and normal male segregated into male and female in equal proportion, while the hybrids from female homo-sexual crosses produced only female plants. This indicated that sex of kakrol is controlled by a single factor; male being heterozygous and the female is homozygous recessive. The possibility to evaluate both parents for fruit characteristics should facilitate breeding.  相似文献   

Aggressiveness of eight <Emphasis Type="Italic">Didymella rabiei</Emphasis> isolates from domesticated and wild chickpea native to Turkey and Israel,a case study     

Hilal Ozkilinc  Omer Frenkel  Dani Shtienberg  Shahal Abbo  Amir Sherman  Abdullah Kahraman  Canan Can 《European journal of plant pathology / European Foundation for Plant Pathology》2011,131(3):529-537

Ascochyta blight, caused by Didymella rabiei, affects both domesticated chickpea and its congeneric wild relatives. The aim of this study was to compare the aggressiveness of D. rabiei isolates from wild and domesticated Cicer spp. in Turkey and Israel on wild and domesticated hosts from both countries. A total of eight isolates of D. rabiei sampled from C. pinnatifidum, C. judaicum and C. arietinum in Turkey and Israel was tested on two domesticated chickpea cultivars and two wild Cicer accessions from Turkey and Israel. Using cross-inoculation experiments, we compared pathogen aggressiveness across the different pathogen and host origin combinations. Two measures of aggressiveness were used, incubation period and relative area under the disease progress curve. The eight tested isolates infected all of the host plants, but were more aggressive on their original hosts with one exception; Turkish domesticated isolates were less aggressive on their domesticated host in comparison to the aggressiveness of Israeli domesticated isolates on Turkish domesticated chickpea. C. judaicum plants were highly resistant against all of the isolates from different origins except for their own isolates. Regardless of the country of origin, the wild isolates were highly aggressive on domesticated chickpea while the domesticated isolates were less aggressive on the wild hosts compared with the wild isolates. These results suggest that the aggressiveness pattern of D. rabiei on different hosts could have been shaped by adaptation to the distinct ecological niches of wild vs. domesticated chickpea.  相似文献

Plants in their natural environment are constantly subjected to various abiotic and biotic stressors and, therefore, have developed several defense mechanisms to maintain fitness. Stress responses are intricate and require various physiological, biochemical, and cellular changes in plants. The reaction mechanisms in plants subjected to drought, salinity, or heat stress alone have been explained in numerous studies. However, the field conditions are significantly different from the controlled lab...  相似文献

Partial identification of antifungal compounds from Punica granatum peel extracts     

Glazer I  Masaphy S  Marciano P  Bar-Ilan I  Holland D  Kerem Z  Amir R 《Journal of agricultural and food chemistry》2012,60(19):4841-4848

Aqueous extracts of pomegranate peels were assayed in vitro for their antifungal activity against six rot fungi that cause fruit and vegetable decay during storage. The growth rates of Alternaria alternata , Stemphylium botryosum , and Fusarium spp. were significantly inhibited by the extracts. The growth rates were negatively correlated with the levels of total polyphenolic compounds in the extract and particularly with punicalagins, the major ellagitannins in pomegranate peels. Ellagitannins were also found to be the main compounds in the bioactive fractions using bioautograms, and punicalagins were identified as the main bioactive compounds using chromatographic separation. These results suggest that ellagitannins, and more specifically punicalagins, which are the dominant compounds in pomegranate peels, may be used as a control agent of storage diseases and to reduce the use of synthetic fungicides.  相似文献   

Removal of Arsenic, Boron, and Selenium from Excavated Rocks by Consecutive Washing     

Carlito Baltazar Tabelin  Amir Hamzah Mohd Basri  Toshifumi Igarashi  Tetsuro Yoneda 《Water, air, and soil pollution》2012,223(7):4153-4167

This paper describes the leaching behavior and release mechanisms of arsenic (As), boron (B), and selenium (Se) from excavated rocks using sequential extraction for solid-phase fractionation, batch experiments with pH variation, and consecutive batch experiments with changes in the solid?Cliquid mixing ratios. Arsenic in the excavated rock was mostly found with the sulfides/organic matter fraction while majority of the leachable B and Se were associated with the exchangeable phases. The leaching of As was strongly pH dependent, Se was pH dependent only around the acidic region, and B was pH independent. Consecutive washing technique with deionized water effectively lowered the B and Se concentrations in the leachate below the drinking water standards of Japan, but was inefficient in the removal of As. Arsenic exhibited non-conservative leaching behavior and its movement was affected by processes like dissolution, precipitation, and pyrite oxidation. In contrast, B and Se behaved more conservatively, resulting in their easy removal from the excavated rock by simple washing and dilution.  相似文献
