为研究不同砧木和中间砧对"红美人"杂柑生产的影响,促进"红美人"产业高效可持续发展,选用7种国内主要砧木品种(宁海香橙、资阳香橙、小红橙、福桔、枸头橙、卡里佐枳橙、小叶大花枳)和5种中间砧(本地早桔、大叶尾张温州蜜柑、大分温州蜜柑、椪柑、宫川温州蜜柑,基砧均为小叶大花枳),研究其嫁接"红美人"后的嫁接口愈合情况、成活率及树体生长情况。结果表明,不同砧木品种中,资阳香橙砧"红美人"的嫁接口愈合好、成活率高且长势最强;小红橙砧"红美人"嫁接口愈合一般;宁海香橙砧"红美人"长势最差。在不同中间砧"红美人"中,大分中间砧"红美人"生长最好,嫁接口愈合好且嫁接成活率高、接穗生长量大,大叶尾张中间砧"红美人"与其表现相近;宫川中间砧"红美人"次之;以本地早和椪柑为中间砧,嫁接口愈合程度及嫁接成活率稍差,易出现"大小脚"情况。  相似文献

The sour cherry is known to exhibit the phenomenon of gametophytic self-incompatibility which prevents self-fertilization. In sour cherry, besides self-incompatible cultivars, there often occur self-compatible cultivars. This is due to the occurrence of natural mutations of the S-RNase or SFB genes and, consequently, loss of functionality of S-alleles. Here we present the results of the identification of S-haplotypes of 21 cultivars of sour cherry from various regions of Europe. The analyses were performed using methods based on the amplification of intron I and intron II of the S-RNase gene and fragments specific to the individual alleles of the S-RNase or SFB genes. The tested cultivars were found to contain 15 S-haplotypes: S1, S1?, S4, S6, S6m, S6m2, S9, S12, S13, S13?, S26, S35, S36a, S36b, and S36b2. The most frequently occurring S-haplotypes were S13? (61.9%), S36a (57.1%), and S26 (47.6%). On the basis of the results, 17 of the 21 cultivars were deduced to be self-compatible. The results will be of use in the production of sour cherry fruit by facilitating the selection of suitable pollinating cultivars. The results are also expected to be useful in the breeding of new cultivars of sour cherry when selecting genotypes for crosses.  相似文献

Volatile organic compounds (VOC) are emitted by many plants. In this study, sixty common plant species of the Vidarbha region of Maharashtra, India were examined for VOC (isoprene and monoterpene) emissions. Plant species VOC emission rates ranged from undetectable to 75.2 μg g?1 h?1. Dalbergia sissoo exhibited a maximum VOC emission rate of 75.2 μg g?1 h?1. Ozone forming potentials (OFP) of the sixty plant species were also estimated using the method of Benjamin and Winer (1998). Maximum ozone forming potential of 77 g O3 (tree)?1 d?1 was observed in the case of Mangifera indica. Out of 60 species, 26 species (43.3%) had low OFP (less than 1 g O3 (tree)?1 d?1), 18 species (30%) had medium OFP (less than 1–10 g O3 (tree)?1 d?1) and 16 species (26.7%) had high OFP (more than 10 g O3 (tree)?1 d?1).  相似文献

Soil solarization, used to control weeds and soil-borne pathogens in hot climates, has not yet been widely adapted as a commercial practice because of its lack of efficacy. Experiments were carried out in southern Italy over two growing seasons to study the effect of three levels (0, 0.35 and 0.7 kg m−2) of organic supplementation of the soil prior to solarization on soil mineral availability and fruit quality attributes. Soil temperature and chemical properties were monitored, together with changes in the physical characteristics and chemical composition of tomato fruits grown under commercial greenhouse conditions. Organic supplementation increased the soil temperature achieved through solarization by 3.9 to 5.5 °C. Organic supplementation increased (P ≤ 0.05) the soil concentration of NO3−-N, exchangeable K2O, Ca2+, Na+ and Mg2+ and the level of electrical conductivity in the soil extract. Physical characteristics of tomato fruits were improved by supplementation, with fresh and dry weight enhanced up to 11 and 21%, respectively, mesocarp thickness up to 19%, firmness up to 36% and skin redness (a*/b* ratio) up to 24%. As the supplementation rate was raised from 0 to 0.7 kg m−2, the fruit content of reducing sugars increased (P ≤ 0.01) from 1.75 to 2.14 g per 100 g f.w., ash from 0.49 to 0.62%, soluble solid from 5.12 to 6.18 °Brix, titratable acidity from 0.16 to 0.19%, and ascorbic acid from 25.1 to 32.5 mg 100 mL−1. We concluded that organic supplementation appears to be a valuable and environmentally friendly way to improve the mineral availability in the soil and improve fruit quality of tomato.  相似文献

A comparison in non-blotches and blotches of 35 cultivars of Xibei tree peony was investigated to explore flower coloration of Xibei tree peony (the second cultivar group in Chinese tree peony). With high performance liquid chromatography (HPLC) analysis, six anthocyanins including peonidin 3,5-di-O-glucoside (Pn3G5G), peonidin 3-O-glucoside (Pn3G), cyanidin 3,5-di-O-glucoside (Cy3G5G), cyanidin 3-O-glucoside (Cy3G), pelargonidin 3,5-di-O-glucoside (Pg3G5G), and pelargonidin 3-O-glucoside (Pg3G) were detected in non-blotches and blotches of petals. Total anthocyanins (TA), total flavones and flavonols (TF), and the copigmentation index (CI) were also analyzed. Cyanidin-based glycosides, which accumulated abundantly at the basal petal, resulted in blotch formation. Some peculiar cultivars with only one kind of anthocyanins or without anthocyanins in non-blotches were found in this study. For example, ‘Feng Zi Xiu Se’, ‘Ou Duan Si Lian’, and ‘Xi Wang’ contained only Pn3G5G; ‘Bing Shan Cang Yu’ and ‘Jin Bo Dang Yang’ contained only Cy3G; while no anthocyanins were found in ‘Bing Shan Xue Lian’. Several cultivars were rich in Pg-based glycosides, such as ‘Ni Hong Huan Cai’, and ‘Ju Yuan Shao Nv’. These cultivars would be excellent parents for creating new cultivars with novel flower color in the future.  相似文献

Seven chilli landraces of Manipur belonging to three cultivated species of Capsicum (Capsicum annuum, Capsicum frutescens, and Capsicum chinense) form economically important food crops of the region. The genotypes were characterized using ten random amplified polymorphic DNA (RAPD) markers. The cluster analysis based on Jaccard's similarity coefficient calculated by UPGMA method differentiated the genotypes into two main cluster groups. One cluster represented the C. annuum genotypes while the other cluster represented the C. frutescens and the C. chinense genotypes. C. chinense genotypes were more close to C. frutescens genotypes. Genetic variation between the C. frutescens genotypes was more than among the C. annuum genotypes and the C. chinense genotypes were the least similar ones.  相似文献

Summary

We investigated the functional differences in three pairs of S-RNase alleles having similar sequences. It was confirmed using pollination tests that S19 and S28 behaved as different alleles, while S17 and S19 appeared to be the same allele. Our previous new allele designation of S6b in place of S17 and S19, and not S19 and S28, from S-RNase sequence analyses was therefore confirmed. The deduced amino acid sequences of S3 and S10, although showing high similarity (94%), were functionally distinct.  相似文献

The Japanese pear ‘Osa-Nijisseiki’ (S2S4SM) (SM = stylar-part mutant) is a self-compatible bud mutant that originated from self-incompatible ‘Nijisseiki’ (S2S4). The S4-allele of the pear is deleted and it shows unilateral incompatibility to cultivar with an S2S4 genotype. However, when pollen-tube growth was compared between cross-compatible [‘Osa-Nijisseiki’ × ‘Okusankichi’ (S5S7)], unilateral-compatible [‘Osa-Nijisseiki’ × ‘Kikusui’ (S2S4)], self-compatible (‘Osa-Nijisseiki’ × ‘Osa-Nijisseiki’), and unilateral-incompatible pollination (‘Kikusui’ × ‘Osa-Nijisseiki’), pollen-tube growth clearly showed the following order: cross-compatible > unilateral-compatible > self-compatible > unilateral-incompatible. This indicates that the ‘Osa-Nijisseiki’ style produces specific inhibitor(s) not only to S2- and S4-pollen but also “self-pollen”, because the phenotype of S4SM-pollen is the same as S4-pollen. Stylar protein analysis demonstrated that ‘Osa-Nijisseiki’ produces S2-RNase (RNase associated with S2-allele) together with a small amount of S4-RNase. The purified S4-RNase possessed almost the same inhibitory action on the growth of S4-pollen-tubes in vitro at 1 μg μl−1 as that from original ‘Nijisseiki’. These results suggest that the depressed growth of unilateral-compatible and self-pollen-tubes in ‘Osa-Nijisseiki’ is due to this biologically active S4-RNase. Growth of self-pollen-tubes may also be depressed by inhibitor(s) specific to “self-pollen” unrelated to S-alleles.  相似文献
