(1) The major characteristics of leaf calls of Zn-deficient plants are that the cytoplasm, the endoplasmic reticulum and the ribosomes are poor, and that there are generally big starch grains in the chloroplasts. (2) After the sprinkling of zinc fertilizer, the structure of leaf cells returns to normal; the [cytoplasm is rich, the amount of chloroplast increases, and a lot of rough endoplasmic rgticulum with various shapes in the cytoplasm can be found. Furthermore, the complented Zinc can promote the photosynthesis of Zn-def icient plants and improve their N-metabolism, so that the yield of the fruit can be increased and the quality improved

柑桔缺锌导致发生叶脉间缺绿症,喷施锌肥后此种症状即可消除。使用电镜研究了缺锌柑桔树叶片及喷施锌肥消除缺绿症后的叶片超微结构,发现缺锌叶细胞的主要特征是细胞质基质、内质网及核糖体稀少及叶绿体中包含有大的淀粉粒。喷施锌肥后可使细胞结构恢复正常,细胞质浓厚,叶绿体数量增加,并出现大量多种形态的粗面内质网,从而可改善氮素代谢,促进光合作用,增加产量,改良品质。

Pot experiment was carried on semihydroge-nic soil to study the effect of potassium on the fun-ction of photosynthetic apparatus of rice (oryzasativa L). The available N, P and K in the soil were17.3 ppm, 23.8 ppm and 25 ppm, respectively,and the total N, P and K were 0. 13%,0.07% and0.42%, respectively. Each pot was filled with15 kg soil with 2.25 g N as urea, 1.5g P_2O_5 as su-perphosphate and different doses of K_2O as potas-sium chloride. All fertilizers were used as basaldressing. Measurements were made...

Pot experiment was carried on semihydroge-nic soil to study the effect of potassium on the fun-ction of photosynthetic apparatus of rice (oryzasativa L). The available N, P and K in the soil were17.3 ppm, 23.8 ppm and 25 ppm, respectively,and the total N, P and K were 0. 13%,0.07% and0.42%, respectively. Each pot was filled with15 kg soil with 2.25 g N as urea, 1.5g P_2O_5 as su-perphosphate and different doses of K_2O as potas-sium chloride. All fertilizers were used as basaldressing. Measurements were made at differentdevelopmental stages with the 1st, 2nd and 3rdfully expanded leaves, counting from top down-ward. Electron micrographs showed that the ch-loroplasts were oblate and with more grana afterK treatment, while those of K-deficient plantswere shorter and wider with fewer grana. Potas-sium decreased quantum requirement which wasassociated with high activities of Hill reaction andphotophosphorylation of chloroplasts. Treat-ment with K in reaction mixture produced thesame effects. Photographs with scanning mi-croscope of K treatment showed more large pa-pillas on leaf surface than K-deficient treatment.Besides, K treatment increased silicified cells,which were shown very clearly on the vein andformed opal phytoliths which made the leavesmore erect and improved the light environmentof rice plants, and the development of plastidsand the activity of photosynthetic apparatus wereaccelerated. At booting stage, K increased the water po-tential of leaves which was positively correlatedwith net photosynthetic rate. The net photosyn-thetic rate of leaf at filling stage was positivelycorrelated with grain yield of rice.

水稻广陆矮四号和威优35盆栽试验的结果表明,施钾使叶绿体内基粒增多,Hill反应及光合磷酸化活力增强。分蘖末期在叶绿体反应液中添加KCl也可提高非环式光合磷酸化活力。适量施钾降低量子需要量可能与上述效应有关。钾使叶片超微结构改善:乳突大而多;硅化程度明显增加,故叶片更直立。叶水势及净光合率提高,两者呈直线正相关。灌桨期剑叶净光合率与谷粒产量呈直线正相关。

The mechanism of increased yield and sucrose content of sugarcane sprayed with rare earth (RE) solution was studied by means of pot experiments and field production experiments. The results showed that RE could increase the chlorophyll content and improve the ultrastructure of leaves and increase the number of grana and grana lamellae in the chloroplasts. So. it could increase the area of the photosynthetic membranes and the photosynthesis rate of the sugarcane. It could increase the activity of roots and promote...

The mechanism of increased yield and sucrose content of sugarcane sprayed with rare earth (RE) solution was studied by means of pot experiments and field production experiments. The results showed that RE could increase the chlorophyll content and improve the ultrastructure of leaves and increase the number of grana and grana lamellae in the chloroplasts. So. it could increase the area of the photosynthetic membranes and the photosynthesis rate of the sugarcane. It could increase the activity of roots and promote the absorption of more N. P and K. and enhance nutrition metabolism. Sugarcane sprayed with RE solution had high levels of K. Ca. Zn. Cu and relatively low levels of Mn and Na. RE might regulate cane growth by regulating the balance of nutrient elements in the sugarcane.Tbe activity of acid and neutral invertases was raised in the stem elongation stage. But in the maturity stage, the activity of acid invertase was lowered while the activity of neutral invertase still remained very high. The sugarcane sprayed with RE solution grew quickly in the elongation stage and slowed down in the mature period to accumulate sucrose. RE could raise the drought resistance of sugarcane by maintaining the structure and function of the plasmolemma. controlling the osmotic pressure of cells and raising the plasticity of cell walls. It could also raise the salt tolerance of sugarcane by improving the permeability and the selective absorption of the plasmolemma. thus decreasing the harm due to high Na + content.
