Contributions His research has focused on general agriculture and on various citrus species. He is primarily known for his research on citron genetics and shape variability,. He developed an auxin which is instrumental in preserving the style and stigma of the citron; these features figure prominently in determining the halachic status of individual citrons for use as ''etrog Etrog ( he, אֶתְרוֹג, plural: '; Ashkenazi Hebrew: ', plural: ') is the yellow citron or ''Citrus medica'' used by Jews during the week-long holiday of Sukkot as one of the four species.

Hebrew University Of Jerusalem
The Hebrew University of Jerusalem (HUJI; he, הַאוּנִיבֶרְסִיטָה הַעִבְרִית בִּירוּשָׁלַיִם) is a public research university based in Jerusalem, Israel. Co-founded by Albert Einstein and Dr. Chaim Weizmann in July 1918, the public university officially opened in April 1925. It is the second-oldest Israeli university, having been founded 30 years before the establishment of the State of Israel but six years after the older Technion university. The HUJI has three campuses in Jerusalem and one in Rehovot. The world's largest library for Jewish studies—the National Library of Israel—is located on its Edmond J. Safra campus in the Givat Ram neighbourhood of Jerusalem. The university has five affiliated teaching hospitals (including the Hadassah Medical Center), seven faculties, more than 100 research centers, and 315 academic departments. , one-third of all the doctoral candidates in Israel were studying at the HUJI.

Etrog
Etrog ( he, אֶתְרוֹג, plural: '; Ashkenazi Hebrew: ', plural: ') is the yellow citron or ''Citrus medica'' used by Jews during the week-long holiday of Sukkot as one of the four species. Together with the ''lulav'', ''hadass'', and '' aravah'', the ''etrog'' is taken in hand and held or waved during specific portions of the holiday prayers. Special care is often given to selecting an ''etrog'' for the performance of the Sukkot holiday rituals. Etymology The romanization of the Hebrew word as ''etrog'' according to the Sephardic pronunciation is widely used. The Ashkenazi Hebrew pronunciation is ''esrog'' or ''esrig''. It has been transliterated as ''ethrog'' or ''ethrogh'' in scholarly work. The Hebrew word is thought to derive from the Persian name for the fruit, ''turunj'' (), likely borrowed via Aramaic. The Arabic word ''utroj'' or ''etroj'' (or etrog in Egyptian Arabic) أُتْرُجِّ means ''Citrus medica''. Taxonomy In Modern Hebrew, ''etrog'' is the nam ...

Citron
The citron (''Citrus medica''), historically cedrate, is a large fragrant citrus fruit with a thick rind. It is said to resemble a 'huge, rough lemon'. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used in Asian cuisine, traditional medicines, perfume, and religious rituals and offerings. Hybrids of citrons with other citrus are commercially more prominent, notably lemons and many limes. Etymology The fruit's English name "citron" derives ultimately from Latin, ''citrus'', which is also the origin of the genus name. Other languages A source of confusion is that ''citron'' in French and English are false friends, as the French word refers to the lemon, while the English word is translated ''cédrat''. Indeed, into the 16th century, the English name ''citron'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpel
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ...

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halakhah
''Halakha'' (; he, הֲלָכָה, ), also transliterated as ''halacha'', ''halakhah'', and ''halocho'' ( ), is the collective body of Jewish religious laws which is derived from the written and Oral Torah. Halakha is based on biblical commandments (''mitzvot''), subsequent Talmudic and rabbinic laws, and the customs and traditions which were compiled in the many books such as the ''Shulchan Aruch''. ''Halakha'' is often translated as "Jewish law", although a more literal translation of it might be "the way to behave" or "the way of walking". The word is derived from the root which means "to behave" (also "to go" or "to walk"). ''Halakha'' not only guides religious practices and beliefs, it also guides numerous aspects of day-to-day life. Historically, in the Jewish diaspora, ''halakha'' served many Jewish communities as an enforceable avenue of law – both civil and religious, since no differentiation of them exists in classical Judaism. Since the Jewish Enlightenment (''Haska ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Academic Staff Of The Hebrew University Of Jerusalem
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary education, secondary or tertiary education, tertiary higher education, higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 3 ...
