    Notes: Twenty-one spring barley cultivars were tested for their reaction to Pyrenophora teres using three methods of assessment: inoculation of plants grown outdoors, a detached-leaf inoculation assay, and bioassay with P. teres toxins produced in vitro. Dram was the most resistant of the cultivars tested; a number of other cultivars including Goldmarker, Egmont and Georgie were also moderately resistant. Akka and Havila were highly susceptible. Good correlation was obtained between results from the three test methods.

    Notes: Summary The blood clearances of three platinum compounds, cis-dichlorodiammine platinum II (DDP), cis, trans-dichlorodihydroxy-bis-(isopropylamine) platinum IV (CHIP), and cis-dichloro-bis-cyclopropylamine platinum II (CP), were determined in nine patients with malignant disease. The complexes were prepared using radioactive platinum (191Pt and 193Pt). A 10-μCi dose of each complex, containing the equivalent of 1–2 mg elemental platinum, was injected IV into groups of three patients. Serial blood and urine samples were collected over 72 h. No obvious difference was found between the three complexes for blood clearance, median t1/2α being 16.8 (range 11.2–23.5) min and median t1/2β 89 (range 63.7–127) h. The urinary excretion was greatest for CHIP, 60% of injected dose as against 42.6% for CP and 38.8% for DDP. Differences in renal excretion of DDP analogues could indicate potentially less nephrotoxic agents. The use of radioactive Pt will allow in vivo dynamic imaging of the distribution of platinum compounds in areas of interest.

    A comparative study of the distribution in the male rat of platinum-labelled cis-dichlorodiammine platinum (II), cis-trans-dichlorodihydroxy-bis-(isopropylamine) platinum (I), and cis-dichloro-bis-cyclopropylamine platinum (II) (1983)

    Notes: Summary Three platinum derivatives, cis-dichlorodiammine platinum (II), (DDP), cis-trans-dichlorodihydroxy-bis-(isopropylamine)platinum (IV) (CHIP) and cis-dichloro-bis-cyclopropylamine platinum (II) (CP), have been prepared with a gamma-emitting platinum label. The distribution of these complexes was studied in male rats. The results are presented as fractions of the administered radiolabel per gram of tissue and per total organ. Accumulation in the liver was highest initially following CP and lowest after DDP, but by 14 days the levels in kidney and liver were highest with CP. The concentration in the skin was relatively high after all the compounds, but was the most conspicuous after DDP at the early times. In general, patterns of distribution between the other organs were similar with DDP and CP. CHIP, however, exhibited a different pattern of distribution. Over the first 24 h the level of platinum in most tissues declined more rapidly than after either of the other two compounds but the residual label persisted for a longer period. In the kidney there appeared to be a secondary uptake of labelled material, presumably from other tissues. The level present at 14 days after CHIP was also significantly higher in a number of other organs than after the other two drugs. The increase in label in the spleen at the later times may be due to the removal of circulating damaged cells and consistent with the higher levels of residual platinum in the blood. There was also a higher level of residual platinum in the blood especially after IV administration of the labelled agent. The results show that CHIP was cleared at a faster rate from blood and kidney than the other two complexes, results which closely resembled clinical findings with these three agents, to be published elsewhere. The greater retention time of label after CHIP also suggests that longer-term toxicity may follow its repeated administration.

    Notes: Summary The blood and urinary clearances of cis-diammine 1,1-cyclobutane dicarboxylate platinum(II) (CBDCA, JM8) were determined in four patients with malignancy. A 40 μCi iv injection of 191Pt/193Pt (3:1)-labelled CBDCA was followed by serial blood and urine sampling to 72h. The blood clearance was triphasic, mean values for the fast, intermediate, and slow phases being 10.8 min, 2.5 h, and 125 h, respectively. The fraction of activity excreted in the urine within the first 6 h had a mean value of 66.7%, contrasting with 26.4% for cisplatin. There was only a small fraction of CBDCA excreted by the slow phase (1.5%) as against an average of 20% for CHIP and 27% for cisplatin. The early and rapid renal clearance of CBDCA may account for reduced nephrotoxicity.

    Notes: Summary Intergeneric hybrids of Triticum aestivum (2n=42,AABBDD) with Agropyron ciliare (2n= 28,SSYY), A. trachycaulum (2n=28,SSHH), A. yezoense (2n=28,SSYY) and A. scirpeum (2n=28) are reported for the first time. F1 hybrids of T. aestivum were also produced with A. intermedium (2n=42,E1E1E2E2Z1Z1) and A. junceum (2n=14,JuJu). All wheat-Agropyron hybrids were obtained by embryo rescue technique. Cultivars and reciprocal crosses differed for seed set, seed development and F1 plant production. The F1 hybrids were sterile. Attempts to obtain amphiploids were unsuccessful. However, backcross derivatives were obtained with wheat as the recurrent parent. The level of chromosome pairing in A. trachycaulum x wheat, A. yezoense x wheat and wheat x A. junceum hybrids provided no evidence of homologous or homoeologous pairing. Mean pairing frequencies in A. ciliare x wheat, wheat x A. scirpeum and wheat x A. intermedium hybrids indicated homoeologous or autosyndetic pairing. Ph gene was more effective in regulating homoeologous pairing in A. yezoense x wheat hybrids than in A. ciliare x wheat hybrid. Chromosome pairing data of BC1 derivatives indicated that either some of the wheat chromosomes were eliminated or Agropyron chromosomes caused reduced pairing of wheat homologues.

    Notes: Summary Current status of wide hybridization in wheat is considered in the light of the number of hybrids produced, the number of genes transferred to commercial cultivars and their use in world wide agricuture. Some original results are presented and results of other authors are compiled to provide update information regarding wide crosses in wheat. Barriers to wide hybridization and progress made in overcoming such barriers are discussed. Areas requiring more research are indicated.

    Notes: Summary Embryo age and composition of nutrient medium affected plant growth and response to vernalization in winter wheat (Triticum aestivum L.). Root and shoot development was more in older than in younger excised embryos, and more in a medium without kinetin than in one with kinetin. Kinetin (2 mg/l) in the medium did not accelerate vernalization, probably because it tended to inhibit seedling and plant growth. Embryo age and media did not completely replace vernalization. Twenty- and 16-day-old embryos responded by flowering after 4 weeks of vernalization. Among plants raised on a standard medium from 20-day-old embryos and vernalized for 4 weeks, 84.2% flowered by or before 50 days after transplanting. Time from embryo culture to heading for 20-day-old embryos with-4-week vernalization averaged 84.6 days. Immature embryos (16–20 days old) needed only 4 weeks of vernalization compared to 6 weeks for mature embryos. Excised embryos could be vernalized as efficiently as seedlings raised by embryo culture. Embryo culture at 16–20 days after anthesis coupled with 4-week cold treatment shortens generation time of winter wheat by about 40 days.

    Notes: Abstract Segments of young inflorescences of Triticum aestivum cv. Chinese Spring (CS), its F1 hybrids with Agropyron trachycaulum and A. scirpeum and backcross derivatives with A. yezoense, A. intermedium and A. junceum, and of a A. yezoense x T. aestivum cv. Wichita hybrid were cultured. Different parts of young spikelets of A. trachycaulum x CS F1 and A. yezoense x Wichita F1 's were also cultured. Percent callus induction was lower in wheat than in the wheat-Agropyron hybrids or backcross derivatives. Percent callus induction from different organs in both hybrids was in the descending order of whole spikelet, spikelet without glumes, rachis, and glumes. No plants could be regenerated from calli of wheat and backcross derivatives except those of CS x A. intermedium combination. Callus induction in hybrids varied from 54 to 84% and plant regeneration from 14 to 31%. The regenerants required no vernalization. Variants including one with top-dense spikes and another with elongated spikelets were recovered. Out of eight A. trachycaulm x CS hybrid regenerants, one had anthers and stigma as opposed to neutral flowers of the original hybrid.

    Notes: Abstract Cassia angustifolia (Tinnevelly senna) andC. acutifolia (Alexandrian senna) have great medicinal importance because of their sennoside content in leaves and pods, which are used as purgatives. Such properties have not been observed inC. occidentalis. The maximum growth of theseCassia species was observed in black soil followed by sandy and humus soils. The leaf pigments also increased in black soil. The sennoside content of senna was maximum in sandy soil as compared to other soils.
