Two Phases

The germination of seeds and the growth of the generated plant are two phases of great importance in an olive breeding program. In this work, three stratification treatments and five cultivars (Hojiblanca, Manzanilla Cacereña, Manzanilla de Sevilla, Toffahi, and Uovo di Piccione) used as female parents in a breeding program for table olive were evaluated along two years to improve germination protocols. The stratification treatments affected seed germination (percent seeds with radicle), radicle length, seedling emergence (percent emerged hypocotyls), and the average time of emergence. The cultivars have shown great variability with respect to the requirements of the seeds and seedling growth performance. None of the treatments with heat application (25 °C) after chill (14 °C) improved the percentage of germinated seeds and seedling emergence in any year compared with the control treatment (30 days at 14 °C). Cultivars such as Manzanilla de Sevilla and Toffahi seem to be a good choice of female progenitors to improve emergence rates and to obtain early vigorous progenies, a character that has been related to a shorter juvenile period of the seedlings. Moreover, in these progenies, a clear lower apical dominance was found from the first stages of seedling growth. The olive fruit and seed traits were also influenced by the female parent. In fact, ‘Hojiblanca’ and ‘Uovo di Piccione’ showed a higher number of empty seed fruits and double seed fruits compared with the other studied cultivars.

Aim: This study was conducted to examine the effects of exhaust pollutants and garden soil extract on seed germination and seedling growth of some economically important crops, maize and sunflower. Study Design: The in-vitro experimental design was completely randomized. Place and Duration of Study: The experimental site was Department of Botany, University of Karachi, Pakistan and the experiment was lasted for 10 days in Ecology laboratory. Methodology: The seeds of maize and sunflower were placed in front of the generator to exposed exhaust pollutants daily, 10 minutes, for 10 days. After the exposure of exhaust gas seeds were shifted into Petri dishes. The garden soil was obtained from mini garden of the Department of Botany, University of Karachi. The different concentrations of garden soil with distilled water were made and filtered. This filtered solution was assumed as the standard solution, which was 100%. From this standard solution, further dilution of 25%, 50% and 75% were made. Distilled water was used as a control for the experiment. Three best seedlings were selected from each Petri dish for the determination of mean values of seed germination (percentage), root, shoot and seedling length and seedling dry weight.   Results: This publication will help to understand the importance of exhaust pollutant impact and soil on crop growth and productivity. The soil quality influences plant growth and identifies the impact of exhaust emission on plant growth. The effects of exhaust pollutants of the generator and different concentration of garden soil on seed germination and seedling growth of two important crops Zea mays (L.) maize and sunflower Helianthus annuus (L.) were recorded. The treatment of different concentration of garden soil extract (0, 25, 50, 75, and 100%) affected seed germination percentage, root, shoot, and seedling length and seedling dry weight of both crop species. The soil extract at 25% significantly (p<0.05) affected the seed germination percentage of H. annuus as compared to control. The treatment of soil extract also decreased seedling growth performance of Z. mays and H. annuus as compared to control. A significant (p<0.05) decrease in seedling length of Z. mays becomes evident that exhaust treatment affected the seedling dry weight performance of maize as compared to control. Similarly, exposure of exhaust pollutant affected the seedling dry weight of Z. mays and H. annuus as compared to control treatment.  The effects of garden soil extract on seed germination and seedling growth of Z. mays was found higher as compared H. annuus. Conclusion: It was concluded that the treatment of exhaust emissions from a portable power generator fueled negatively affected the seed germination and seedling growth performance of maize and sunflower as compared to control treatment. A comparison between the seed germination percentage, seedling growth and biomass production performance of maize was found highly affected as compared to sunflower.

The ecotoxicological effects of Zn2+ on germination and early seedling growth of six pulses were investigated. Seeds of these plants were exposed to seven different concentrations of Zn (0, 0.2, 0.4, 0.8, 1.6, 3.2, and 6.4 mM). The results indicated that root growth and shoot elongation of six pulse plants were more sensitive than seed germination and dry weight for measurement of the toxic of Zn2+ pollutions. Different species show different levels of tolerance to Zn2+ pollution. Vigna radiate and Lathyrus odoratus are the most sensitive to Zn2+, their germination percentage, root growth, shoot elongation and dry weight were significantly lower than other tested species, by contrast, Glycine max and Dumasia villosa are the most resist species, their germination and seedling growth almost were not influenced by Zn2+ pollution significantly comparing the control. There were significantly negatively correlations between seedling growth and increasing concentration of Zn2+ for Glycine max, Lathyrus odoratus and Dumasia villosa. The significantly negative correlations between germination and increasing concentration of Zn2+ were show for Lathyrus odoratus.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.

Slow establishment of caucasian clover (Trifolium ambiguum L.) is hindering the use of this legume in pasture mixtures. Improved genetic material is one strategy of correcting the problem. Newly harvested seed of hexaploid caucasian clover germplasm covering a range of origins, together with white and red clover and lucerne, were sown in 1 m rows in a Wakanui soil at Lincoln in November 1995. After 21 days, the caucasian clover material as a group had similar numbers of emerged seedlings as white clover and lucerne, but was inferior to red clover. There was wide variation among caucasian clover lines (48-70% seedling emergence), with the cool-season selection from cv. Monaro ranked the highest. Recurrent selection at low temperatures could be used to select material with improved rates of seedling emergence. Red clover and lucerne seedlings produced significantly greater shoot and root dry weight than caucasian and white clover seedlings. Initially, caucasian clover seedlings partitioned 1:1 shoot to root dry weight compared with 3:1 for white clover. After 2 months, caucasian clover seedlings had similar shoot growth but 3 times the root growth of white clover. Between 2 and 5 months, caucasian clover partitioned more to root and rhizome growth, resulting in a 0.3:1 shoot:root ratio compared with 2:1 for white clover. Both clover species had similar total dry weight after 5 months. Unhindered root/ rhizome devel-opment is very important to hasten the establishment phase of caucasian clover. The caucasian clover lines KZ3 and cool-season, both selections from Monaro, developed seedlings with greater shoot and root growth than cv. Monaro. KZ3 continued to produce greater root growth after 5 months, indicating the genetic potential for improvement in seedling growth rate. Different pasture estab-lishment techniques are proposed that take account of the seedling growth characteristics of caucasian clover.

AbstractAs the global population continues to increase, global food production needs to double by 2050 to meet the demand. Given the current status of the not expansion of cultivated land area, agronomic seedlings are complete, well-formed and strong, which is the basis of high crop yields. The aim of this experiment was to study the effects of seed germination and seedling growth in response to silicon (from water-soluble Si fertilizer). The effects of Si on the maize germination, seedling growth, chlorophyll contents, osmoprotectant contents, antioxidant enzyme activities, non-enzymatic antioxidant contents and stomatal characteristics were studied by soaking Xianyu 335 in solutions of different concentrations of Si (0, 5, 10, 15, 20, and 25 g·L−1). In this study, Si treatments significantly increased the seed germination and per-plant dry weight of seedlings (P < 0.05), and the optimal concentration was 15 g·L−1. As a result of the Si treatment of the seeds, the chlorophyll content, osmotic material accumulation and antioxidant defence system activity increased, reducing membrane system damage, reactive oxygen species contents, and stomatal aperture. The results suggested that 15 g·L−1 Si significantly stimulated seed germination and promoted the growth of maize seedlings, laying a solid foundation for subsequent maize growth.
