Mactra veneriformis is a common economic benthic shellfish with high nutritional value and is widely distributed in the Shandong and Liaoning provinces. Geligang is located in the northern part of Liaodong Bay. It is formed by the water impact of Shuangtaizi and Liaohe River. It has an area of approximately 10 000 hm2 with a fertile substrate. It is an important habitat of beach shellfish, such as M. veneriformis. Studies on the influencing factors of wild population quality traits and their correlation with morphological traits are helpful for developing genetic breeding of marine shellfish. To analyze the effects of morphological traits on quality traits of M. veneriformis at different ages in Geligang, the shell length (SL), shell width (SW), shell height (SH), body weight (BW), and soft tissue wet weight (RW) of 1–3 years old M. veneriformis were analyzed using correlation analysis, path analysis, and multiple regression analysis. The M. veneriformis used in the experiment was obtained from the Geliang in Liaodong Bay in September 2022. A total of 80 1-year-old, 104 2-year-old, and 168 3-year-old M. veneriformis were obtained. The results showed that the morphological traits of M. veneriformis at different growth stages had different contributions to quality traits, and there were significant differences (P < 0.01). SW had the greatest direct effect on the BW of 1–3 year-old M. veneriformis, but had different effects on the RW; SW had the greatest direct effect on 1-year-old M. veneriformis; and SL had the greatest effect on 2- and 3-year-old M. veneriformis. The direct path coefficient of SH to the BW and RW of 2-year-old M. veneriformis did not reach significant level (P > 0.05) and was eliminated. The optimal regression equation of quantitative traits to qualitative traits of 1–3 year-old M. veneriformis was established. The results showed that when BW was the target trait, SW was the main selection trait and SL was the auxiliary selection trait for 1–3 year-old M. veneriformis. When RW was the target trait, SW should be the main selection trait for 1-year-old M. veneriformis, supplemented by SL. The SL should be the main selection trait for both 2- and 3-year-old M. veneriformis, but the SW was the auxiliary selection trait for 2-year-old M. veneriformis, while the SH was for 3-year-old M. veneriformis. In this study, correlation analysis, path analysis, and multiple regression analysis were performed on the morphological traits and quality traits of 1–3 years old M. veneriformis to determine the key morphological traits affecting the quality traits of M. veneriformis at different ages. In this study, the R2 values of the morphological traits of 1- and 2-year-old M. veneriformis (0.898 and 0.859, respectively) were greater than 0.850, indicating that the main factors affecting the body weight of living M. veneriformis were found. However, the R2 value of the morphological traits of 3-year-old M. veneriformis (0.815) was below 0.850, indicating that there may be other influencing traits in addition to the traits analyzed in this study. The reason may be that with the growth of M. veneriformis, the thickness of the shell and the effect on the weight of the living body gradually increase. In this study, the R2 values of morphological traits of 1–3 years old M. veneriformis (0.738, 0.648, and 0.538, respectively) on the wet weight of soft tissue were all below 0.850, indicating that there were other key factors affecting the wet weight of soft tissue. The age of sexual maturity of the M. veneriformis is at 1 year. The development of the gonad in the soft part may be closely related to the size of the wet weight of the soft tissue. The sampling period is mainly in the proliferation to depletion period of the gonad development of M. veneriformis. The gonad development is simultaneously affected by the environment. These results can provide reference for breeding M. veneriformis and the selection of parent shellfish.

To screen excellent individuals of Malania oleifera for oil and medicine, the seeds of 20 M. oleifera individuals from Fengshan County, Bama County, Tianlin County, and Longlin County in Guangxi Zhuang Autonomous Region were selected as research objects. Seed morphological characteristics and fatty acid composition of different individuals were measured and correlation among the character index and geographical environment factor were analyzed. Combined with the results of principal component analysis, the qualities of the different individual seeds tested were comprehensively evaluated. The geographical variation of seed traits was studied using cluster analysis. The results showed that among different M. oleifera individual seeds, the coefficient of variation (Cv) of seed morphological characteristics were 7.63%-24.67%, and the Cv of oil and fatty acid composition contents were 3.69%-24.49%. The Cv of seed weight, kernel weight, water content, palmitic acid content, stearic acid ester content, linoleic acid content, linolenic acid content were more than 10%. The kernel yield and oil content decreased with an increase in latitude and altitude, whereas the oil content increased with an increase in longitude. The erucylacetic acid content increased with an increase in longitude, average temperature, and annual precipitation, and decreased with an increase in altitude. The erucylacetic acid content in the kernel with higher oil content was higher, and the content of other fatty acids decreased. Among the top five seedling individuals in principal component analysis, LL2 had excellent seed morphological characteristics with the highest seed weight and kernel weight. FS5, BM2, FS7, and TL1 had excellent comprehensive quality with high oil content and erucylacetic acid content, large longitudinal diameter, and high kernel weight. In addition, TL3 had excellent single character with the highest kernel yield (83.77%), BM1 had excellent single character with the highest oil content (66.77%) and erucylacetic acid content (49.013%). Individuals with the best single and comprehensive characteristics can be used as oil and nervonic acid resources and for cultivating excellent M. oleifera cultivars. [ABSTRACT FROM AUTHOR]

Objective To establish and improve the quality standard of ginkgo semen decoction pieces. Methods The morphological character for 29 batches of ginkgo gemen and 12 batches of stir-fried ginkgo gemen were observed, and the moisture contents were assayed using the method in Chinese Pharmacopoeia 2015 edition, the first supplement. Results The character of ginkgo gemen and stir-fried ginkgo gemen were consistent in different batches. The moisture content of ginkgo gemen was 8.8% to 12.2%, with an average of 10.5%. The moisture content of stir-fried ginkgo gemen was from 5.4% to 12.3%, with an average of 8.9%. Considering that ginkgo semen decoction pieces are stored for a long time, they are prone to the attack of mildew and insects, and the moisture limit is set to be no more than 10.0% in ginkgo gemen and stir-fried ginkgo. Conclusion Compared with the Chinese Pharmacopoeia 2015 edition, the first supplement, the character identification for ginkgo semen decoction pieces was added and the quality standards were improved. The moisture content of ginkgo semen decoction pieces needs to be strictly controlled under 10.0% to prevent mildew and insects. [ABSTRACT FROM AUTHOR]

Drought was one of the important factors for restricting wheat safety production in China, even all over the world. Drought-resistance index and morphological index of drought resistance identification were compared to find appropriate drought-resistance index and related morphological index for evaluating wheat drought tolerance. The two factor split plots were designed, the main factors was water treatment, deputy factors was wheat materials, drought stress morphological characteristics and drought resistance index of 100 different genotype wheat were studied during whole growth period at drought shelter (drought stress) and normal water supply. The results showed that the drought co-- efficient (DC) was no significant correlation with wheat yield under drought stress (Yd) and normal water supply (Yw). The correlation coefficient between drought index (DI) and Yd was 0. 8696,there was no significant correlation with Yw (correlation=0.0602). The correlation coefficients for arithmetic mean productivity (MP) and wheat yield (Yd and Yw) were 0. 9526 and 0.7101, respectively. The geometric aver-age productivity of GMP and Yw correlation coefficient is 0. 9482,and Yd correlation coefficient is 0. 6929. And the correlation coefficient for drought tolerance index for variety screening (DTIv) and Yw was-O. 3892,and Yd was 0. 5368. Grain yield per plant, plant biomass per plant, spikelet number, tillering number per plant under drought stress were highly correlated to drought resistance of wheat, correlation was 0. 9397,0. 9386,0. 9201 and 0. 9187, respectively. Therefore, DI and MP reflected wheat drought resistance, which could be used as preferable parameters to evaluate wheat drought resistance. The grain yield per plant, biomass,spikelet number per tiller number per plant under drought stress were more intuitive agronom-ic traits to estimate wheat drought resistance. [ABSTRACT FROM AUTHOR]

Al-20 Sr intermediate alloys were prepared by both mold and suction castings. The morphological evolution of the primary Al4Sr phase under different solidification conditions was investigated by SEM. The results showed that in the mold cast specimens the primary Al4Sr phases are regular and complete block-like shape at 850℃ and are strip-like form with obvious preferential crystallographic growth character at 950℃. In the suction cast specimens， the primary Al4Sr phases are regular and complete block-like shape when the temperature is increased to 850℃， fine bamboo-like shapes in the central and short strip-like and elliptical forms in the peripheral regions when the temperatures are increased to 900℃ and 950℃ and then decreased to 900℃， coarse and fine stripe-like shapes when the temperatures are decreased to 850℃ and 800℃， and coarse stripe-like forms when the temperature is decreased to 750℃， respectively. In summary， solidification conditions have important influence on the morphologies of Al4Sr phase. [ABSTRACT FROM AUTHOR]
