Its fruits are an alternative source of income for the local populations with potential for agro-industry. This generates a demand for seedlings that is limited by the difficult propagation due to the dormancy of the seeds. Thus, this work aimed to develop a method capable of accelerating germination by overcoming dormancy. Pyrenes from four inflorescences were harvested from different trees in the municipality of Três de Maio/Brazil. In the first experiment, the pyrenes were warm-stratified at 40°C for 0 (control), 1, 2, 3 or 4 weeks. In experiment 2, pyrenes scarified manually (removal of the endocarp germ pore) or using H2SO4 for 5 or 10 minutes were subsequently warm-stratified for four weeks. In experiment 3, pyrenes subjected to physical scarification were warm-stratified for 4, 5, 6 or 8 weeks. Analyses showed that there was a significant effect of the preheating and scarification treatments on the emergence of B. yatay seedlings. Pyrenes mechanically scarified (opening of the germ pore) and subsequently subjected to preheating at 40°C for five weeks produced the highest speed of emergence index, with about 28 seedlings emerged from 100 sown pyrenes.","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67091542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These equations have species-specific parameters which quantify the inherent longevity of seeds of a particular species and their sensitivity to change in moisture content. This research investigated the effect of moisture content on lentil (Lens culinaris) seed longevity during experimental storage. Seeds of an elite breeding line were stored under hermetic conditions at six different moisture contents (7.6, 8.1, 8.8, 10.1, 11.5, 12.6%) at 60°C. Ability to germinate was determined at scheduled intervals, and longevity (σ) was estimated for each treatment. The values of the constants KE (8.0008) and CW (3.746) were estimated using linear regression, by plotting log σ against log moisture content, combined with the universal temperature constants (CH = 0.0329, CQ = 0.000478). The application of these moisture constants (KE and CW) was tested by comparing the predicted viability loss of two lentil accessions with their observed longevity under hermetic storage at 12.0% moisture content and 45°C. The validity of these constants for predicting lentil seed longevity was proven, with an R2 = 0.912 (P < 0.001).","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67090753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the effects of on-farm priming on the germination performance of maize seeds with different vigour levels. Two maize hybrids\u0000 and four inbred lines were used as experimental materials. Soaking treatment significantly decreased the final germination percentage of low- vigour seeds and had no beneficial effects on high-vigour seeds. With longer soaking times, the reduction in germination increased and there was a positive,\u0000 negative or neutral effect of water soaking on the germination index. The responses of seeds to on-farm priming varied among the different hybrid / inbred lines used and depending on the length of the treatment. Reducing imbibition damage by PEG soaking had little impact on the poor germination\u0000 induced by soaking in water. Removal of the seed pericarp alleviated the negative effects of soaking on germination. This study has demonstrated, for the first time, the differential effects of water soaking on maize seeds with different vigour levels.

Among the techniques used to promote germination, seeds priming has been found to play a key role. In the present study, a set of different priming agents (KCl, KH2PO4, CaCl2\u0000 and PEG 8000) was tested on seeds of two leek (Allium ampeloprasum L.) cultivars (\"Lungo della riviera\" and \"Monstrueux de Carentan\") to assess the effects on germination performances both in optimal hydration condition (Ψw = 0 MPa) and under water deficit (–0.3\u0000 and –0.6 MPa). Germination percentage of \"Lungo della riviera\" was improved by PEG and KCl at –0.3 MPa and –0.6 MPa, respectively, whereas CaCl2 improved germination of \"Monstrueux de Carentan\" at –0.6 MPa. Osmopriming was beneficial in terms of germination\u0000 rate although to different extent depending on genotype and priming agent. The hydrotime model showed that the effects of priming on germination rate was mostly due to a lowering of the predicted hydrotime constant (θH), whereas median base water potential Ψb\u0000 (50) tended to increase following treatments albeit with some exception. In this study, hydrotime model proved to be a useful tool to test the effectiveness of different priming treatments on leek seeds and the intraspecific variability in germination capability and speed under water stress.","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41876994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, InDel markers developed by comparing whole genome re-sequencing data were used to analyze the genetic diversity of a bitter gourd germplasm sample from various geographical origins. To verify the reliability of the set of InDel markers identified, 220 pairs of InDel primers were designed. The primers were preliminarily detected by 8% polyacrylamide gel electrophoresis, and 25 pairs of primers with better polymorphism were screened. Using the 25 primer combinations, the 53 bitter gourd accessions were effectively distinguished and the InDel fingerprint of DNA was constructed. Concomitantly, the degree of purity of different crosses was determined based on the differences in specific bands among genotypes. The unweighted pair-group method with arithmetic means showed that the 53 bitter gourd materials may be divided into three groups, with a similarity coefficient of 0.645 as the threshold. Therefore, this study can provide many InDel markers for genotypic identification, genetic relationship analysis, and genetic map construction of bitter gourd.","PeriodicalId":21662,"journal":{"name":"Seed Science and Technology","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42429134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two tomato seed lots were used, differing in physiological quality: the low quality seed lot had 76% germination and the medium quality seed lot had 87% germination. Seeds were coated with a complete PNF containing N, P, K, Ca, Mg, Fe, B, Mn, Cu and Zn. The PNF was applied at three concentrations, i.e., 1-fold (PF1), 4-fold (PF4) and 16-fold (PF16), and applied with 3% PVP-K90 + 1% PEG 6000 as a polymer. Coating seeds with PNF improved seed germination for both low- and medium-quality seeds. Accelerated ageing tests revealed that PF1 increased germination by 12 and 27% in low- and medium-quality seeds, respectively. All concentrations of PNF increased TDH activity after 48 hours of seed imbibition. Moreover, PF16 decreased root length but increased shoot length.
