. Alfalfa ( Medicago sativa L.) is a globally important leguminous fodder crop because of its high production and nutritional value. The investigation was conducted to determine an effect of 3-Indole Acetic Acid (IAA) and Gibberellic acid (GA3) on the alfalfa BC 3 hybrid at the breeding room of the institute of grassland science, Yangzhou University, Jiangsu Province, China. Plant height, stem diameter, leaves number per plant, leaf length, leaf width, leaf area, fresh shoot weight, and dry shoot weight were measured. The study used four different IAA and GA3 concentrations (0, 50, 75, and 100 mg L -1 ) with three replications in a completely randomized design. The results revealed that the use of IAA and GA3 was significantly effective in the growth of the alfalfa BC 3 hybrid at the two cutting times. The use of 25 mg L -1 IAA concentration was significantly improved the plant height, leaf width, and leaf area. Exogenous GA3 application significantly enhanced stem diameter, leaf length, leaf area, fresh shoot weight, and dry shoot weight, except for leaf width, which showed a non-significant difference but was higher than that in the control group. Thus, the application of GA3 (i.e., GA3 at 75 mg L -1 ) can be suggested for a higher yield of the alfalfa BC 3 hybrid.

. Rawdhat Abalworood in Al-Qassim region of Saudi Arabia is one of the most important rawdhats of this area. The present study provides insight of vegetation types, life forms, as well as floristic categories and species distribution, highlighting the ecological factors that influence species distribution. A total of 44 species representing 19 families of vascular plants were recorded. The dominating groups were Asteraceae and Brassicaceae, and the dominant life forms were therophytes and chamaephytes, displaying a typical desert life-form range. Two of the eighteen studied sites had the maximum species richness value of 15 species per plot. Five of the 18 sites studied had the lowest species richness assessing of 10 species per plot. The most frequent life form classes observed in Rawdhat Abalworood, Al-Asyah, Al-Qassim region were Therophytes (Th) and Chamaephytes (Ch), with 65.91% and 15.91%, respectively. Chorological analysis exhibited Saharo-Sindian (SA-SI) and Irano-Turanian-Saharo-Sindian (IR-TR+SA-SI) represented by 20.45% and 18.18, respectively. Chronologically, surveyed plant species were recognized into three categories; mono regional, bi regional, and pluri regional. The three chorological categories were represented by 31.81%, 50.0%, and 18.18%; respectively. Species diversity in terms of Margalef’s diversity index ( Figure 6A ) ranged between 1.6 to 2.6 with an average of 2.1 to 0.3, Shannon-Weiner diversity index ( Figure 6D ) showed close diversity levels as Margalef’s and ranged between 1.6 to 2.4 with an average of 2.1. Using CCA multivariate analysis effect of 6 environmental factors is distinguished upon vegetation. The CCA ordination revealed that the separation of Vegetation group III along the axis was influenced by Silt, WHC, OM, OC, and Clay, whereas VG II was substantially related to sand%.

. Individuals of 13 lily varieties were treated in artificial climate chambers at a day/night temperature of 25/15 °C as control, and low-temperature at 15/5 °C for 1 day (D 1 ), 3 days (D 2 ), 5 days (D 3 ) respectively, and rewarmed under the control temperature for 2 days (D 4 ) after D 3 treatment. The physiological indexes including electrical conductivity (Rec), osmotic adjustment substance contents of proline (Pro), soluble sugar (SS) and soluble protein (SP), and activity of superoxide dismutase (SOD) were measured. The results showed that the Rec of most varieties increased significantly under 1 day low-temperature stress and then showed a decreasing trend with the extension of stress time. The Pro of all varieties increased significantly under low-temperature stress, but the SP of most varieties decreased significantly. The SS content of more than half of the varieties increased significantly with the extension of low-temperature stress. The SOD activities of all varieties increased and most of them increased significantly under stress. After rewarming, the Rec of 54% of the varieties increased, and 31% increased significantly compared with D 3 . SS contents of about 62% of the varieties and SP contents of about 46% of the varieties increased significantly. Pro contents of 77% of the varieties decreased. The SOD activity of 77% of the varieties increased and 31% of the varieties increased significantly. After comprehensive analysis by the membership function method the cold adaptability of lily varieties showed a descending order as Concad’Or > Tiber > Asopus > Golden Matrlx > Red twin > Willmottiae > Orange Matrlx > Maximowiczii > Viviana Zantriana > Dauricum > Maldano > Robina > Eyeliner. The results of this study provided a theoretical basis for screening suitable lily varieties for gardens in the northeast of China.
。将13个百合品种分别置于25/15℃昼夜温度的人工气候室中，分别在15/5℃低温条件下处理1 D (d1)、3 D (d2)、5 D (d3)， d3处理后在对照温度下再加热2 D (d3)。测定了电导率(Rec)、脯氨酸(Pro)、可溶性糖(SS)、可溶性蛋白(SP)渗透调节物质含量和超氧化物歧化酶(SOD)活性等生理指标。结果表明:大多数品种的Rec在1 d低温胁迫下显著升高，然后随着胁迫时间的延长呈下降趋势;低温胁迫下，各品种的Pro均显著升高，但多数品种的SP显著降低。随着低温胁迫时间的延长，半数以上品种的SS含量显著增加。所有品种的SOD活性均升高，且多数品种在胁迫下显著升高。复温后，54%的品种的Rec增加，其中31%的品种与复温前相比显著增加。约62%的品种SS含量和46%的品种SP含量显著增加。77%的品种Pro含量下降。77%的品种SOD活性显著升高，31%的品种显著升高。通过隶属函数法综合分析，百合品种的冷适应性从大到小依次为:conad 'Or > Tiber > Asopus > Golden matrix > Red twin > willmotiae > Orange matrix > Maximowiczii > Viviana Zantriana > Dauricum > Maldano > Robina > Eyeliner。本研究结果为筛选东北地区园林百合适宜品种提供了理论依据。
